During this series of informative podcasts, we'll bring you foundational training on the most popular Oracle technologies. Let's get started! 00:25 Nikita: Welcome to the Oracle University Podcast! I'm Nikita Abraham, Team Lead: Editorial Services with Oracle University, and with me is Lois Houston, Director of Innovation Programs. Lois: Hey there! Last week, we spoke about multicloud, discussing what it is, and the new partnerships we have with Microsoft Azure, Google Cloud, and Amazon Web Services. If you haven't gotten to the episode yet, we suggest you go back and listen to it before you dive into this one. 00:56 Nikita: Joining us again is Samvit Mishra, Senior Manager of CSS OU Cloud Delivery, and we're going to ask him about Oracle Interconnect for Azure. We'll look at the scenarios around Oracle Interconnect for Azure and talk about some considerations too. Hi Samvit! Thanks for being with us today. Samvit: Hi Niki! Hi Lois! Lois: Samvit, you introduced Oracle Interconnect for Azure last week, but tell us, how does it improve the customer experience? What benefits does it offer? 01:25 Samvit: Oracle Interconnect for Azure can be established with a one-time setup, eliminating the need for an intermediary network provider. This cross-cloud direct connection also helps you migrate to the cloud or build cloud-native applications by using the best of OCI and Microsoft Azure. Now, because it is a private connection between Oracle Cloud Infrastructure and Microsoft Azure, you get consistent network performance… around 2 millisecond latency. The interconnect also enables joint customers to take advantage of a unified Identity and Access Management platform. So, you can set up single sign-on between Microsoft Azure and OCI for your Oracle applications, like PeopleSoft and e-Business Suite. 02:16 Nikita: That makes the integration pretty seamless, right? Samvit: Exactly, Niki. Having a federated single sign-on means you authenticate only once to access multiple applications, without signing in separately to access each application. And you also get a secure inter-cloud connection that bypasses the public internet. 02:38 Nikita: How extensive is the global reach of Oracle Cloud Infrastructure and Azure in terms of the number of cloud regions available? Samvit: OCI has the fastest growing network of global data centers, with 50 cloud regions available. And there are 12 Azure interconnect regions. For example, Ashburn in the US is an OCI-Azure interconnect region. 03:01 Lois: Samvit, what is the architecture of Oracle Interconnect for Azure like? How is data transferred securely between a Virtual Cloud Network in Oracle Cloud Infrastructure and a Virtual Network in Microsoft Azure? Samvit: A Virtual Network in a Microsoft Azure region is connected to a Virtual Cloud Network in an OCI region using a private interconnection composed of Azure ExpressRoute and OCI FastConnect. Now, on the OCI side, the FastConnect virtual circuit terminates at a dynamic routing gateway, which is attached to the Virtual Cloud Network. On the Microsoft Azure side, the ExpressRoute connection ends at a virtual network gateway, which is attached to a virtual network. So, traffic from Azure to OCI is routed through the virtual network gateway in Microsoft Azure to the dynamic routing gateway in OCI. What's important to note is that in both directions, the traffic never leaves the private network. 04:05 Nikita: Wow, ok. Samvit, what are some common use cases of Oracle Interconnect for Azure? Can you give us an example of a supported deployment option? Samvit: We can have a .NET application running in Azure that can access an Oracle database in OCI. Similarly, you can also have custom cloud-native applications running on Azure using Oracle Autonomous Database on the OCI side. 04:29 Lois: And are there any prerequisites when you configure Oracle Interconnect for Azure? Samvit: Yes, there are. Remember, on the Azure side, you must have a virtual network with subnets and a virtual network gateway and on the OCI side, you must have a VCN with subnets and an attached dynamic routing gateway. 04:50 Lois: Let's talk about the networking components that are involved in each site of the connection. Can you run us through the comparison? Samvit: Now, if we talk about the virtual network component, on the OCI side, there is a Virtual Cloud Network and on the Azure side, there is a Virtual Network. From a virtual circuit standpoint, in OCI, there is the FastConnect virtual circuit… on the Azure side, there is the ExpressRoute circuit. When it comes to the gateway, on the OCI side, there is the dynamic routing gateway and on the Azure side, there is the virtual network gateway. Similarly, for routing, there are route tables in OCI and Microsoft Azure. From a security standpoint, in OCI, you can configure security lists as well as network security groups and on the Azure side, you have network security groups. 05:44 Nikita: What are the benefits of this partnership? Samvit: This partnership allows you to innovate using the best combination of Oracle's and Microsoft's cloud services based on their features, performance, and pricing. So, in a way, you can combine the capabilities of both cloud vendors. 06:01 Nikita: So, a one-stop shop. Samvit: Exactly, Niki. This partnership also gives you a highly optimized, secure, and unified cross-cloud experience so you can use the best of services from Oracle Cloud Infrastructure and Microsoft Azure. And the best part is you continue to leverage any existing investment in Oracle and Microsoft technologies. 06:24 Lois: I wanted to ask you about the typical scenarios where Oracle Interconnect for Azure is supported. Samvit: There are many scenarios where this Interconnect is supported. Let me run you through a couple of them. You could connect an OCI Virtual Cloud Network to an Azure Virtual Network. That's a scenario that is supported. You could connect peered OCI VCNs in the same region to Azure. You could connect peered OCI VCNs in different regions to Azure. You could also connect services in Oracle Services Network to Azure. 06:59 Lois: And are there any scenarios where this interconnect is not supported? Samvit: When the scenario involves connecting an on-premises environment to Azure via OCI VCN and vice versa, that is not supported. 07:16 Unlock the power of AI Vector Search with our new course and certification. Get more accurate search results, handle complex datasets easily, and supercharge your data-driven decisions. From now through May 15, 2025, we are waiving the certification exam fee (valued at $245). Visit mylearn.oracle.com to enroll. 07:42 Nikita: Welcome back! I want to explore these scenarios in a little more detail, Samvit. Samvit: OK. Imagine you have OCI on one side and Azure on the other. In this scenario, we have a dynamic routing gateway in OCI and a virtual network gateway in Azure. This is a basic configuration. With Oracle FastConnect and Azure ExpressRoute, customers can create a private interconnection between their OCI and Azure environments. Now in another scenario, we have VCNs in OCI, and they're peered together using a dynamic routing gateway. With this local peering, the peered VCN can talk to Azure through Oracle Interconnect for Azure. Here's another scenario. We have VCNs in different OCI regions: one VCN in OCI Region 1 and another in OCI Region 2, with Azure sitting alongside. They have established a remote peering connection, and each VCN has its own dynamic routing gateway. Here's the kicker—the peered VCN in this architecture can also converse with Azure using the interconnect. Now think about this scenario. We have the dynamic routing gateway, but we have also added a service gateway to the VCN in OCI. This service gateway allows your VCN to privately access specific Oracle services without exposing data to the public internet. No internet gateway or NAT gateway is required to reach those specific services. Now, traffic from the VCN to the Oracle Services Network travels over the Oracle network fabric and never traverses the internet. Using Oracle Interconnect for Azure, resources in Azure can also privately access resources in Oracle Services Network. 09:38 Nikita: What are the bandwidth and cost considerations? Samvit: Pricing is based solely on the port capabilities of OCI FastConnect and your ExpressRoute. One thing you need to understand is that the cost of FastConnect is the same across all OCI regions. And there are no separate ingress or egress data charges. The cost of Azure ExpressRoute varies across regions and Oracle recommends that you use the local setting, which has no separate ingress or egress charges. Azure ExpressRoute supports up to 10 GB as bandwidth. FastConnect is available in 1, 2, 5, or 10 Gbps. So, the recommendation here is to choose one of these matching bandwidth options under ExpressRoute. 10:27 Lois: Thank you, Samvit, for taking the time to talk to us about Oracle Interconnect for Azure. Samvit: Thank you for having me. Nikita: Remember, Oracle also offers an interconnect solution with Google Cloud, which is very similar to the one with Azure. It too provides a direct, high-performance, and secure network connection with Oracle Cloud Infrastructure. So, if you want to learn more about it, head over to mylearn.oracle.com and search for the Oracle Cloud Infrastructure Multicloud Architect Professional course. Lois: In our next episode, we'll take a close look at Oracle Database@Azure service.

In this episode, hosts Lois Houston and Nikita Abraham speak with senior OCI instructor Mahendra Mehra about the capabilities of self-managed nodes in Kubernetes, including how they offer complete control over worker nodes in your OCI Container Engine for Kubernetes environment. They also explore the various options that are available to effectively manage your Kubernetes deployments. OCI Container Engine for Kubernetes Specialist: https://mylearn.oracle.com/ou/course/oci-container-engine-for-kubernetes-specialist/134971/210836 Oracle University Learning Community: https://education.oracle.com/ou-community LinkedIn: https://www.linkedin.com/showcase/oracle-university/ X (formerly Twitter): https://twitter.com/Oracle_Edu Special thanks to Arijit Ghosh, David Wright, Radhika Banka, and the OU Studio Team for helping us create this episode. -------------------------------------------------------- Episode Transcript: 00:00 Welcome to the Oracle University Podcast, the first stop on your cloud journey. During this series of informative podcasts, we'll bring you foundational training on the most popular Oracle technologies. Let's get started! 00:26 Nikita: Hello and welcome to the Oracle University Podcast! I'm Nikita Abraham, Principal Technical Editor with Oracle University, and with me is Lois Houston, Director of Innovation Programs. Lois: Hi everyone! Last week, we discussed how OKE virtual nodes can offer you a complete serverless Kubernetes experience. Nikita: Yeah, and in today's episode, we'll focus on self-managed nodes, where you get complete control over the worker nodes within your OKE environment. We'll also talk about how you can manage your Kubernetes deployments. 00:57 Lois: To tell us more about this, we have Mahendra Mehra, a senior OCI instructor with Oracle University. Hi Mahendra! Welcome back! Let's get started with self-managed nodes. Can you tell us what they are? Mahendra: In Container Engine for Kubernetes, a self-managed node is essentially a worker node that you personally create and host on a compute instance or instance pool within the compute service. Unlike managed nodes or virtual nodes, self-managed nodes are not grouped into node pools by default. They are often referred to as Bring Your Own Nodes, also abbreviated as BYON. If you wish to streamline administration and manage multiple self-managed nodes collectively, you can utilize the compute service to create a compute instance pool for hosting these nodes. This allows for greater flexibility and customization in your Kubernetes environment. 01:58 Nikita: Mahendra, what are some practical usage scenarios for OKE self-managed nodes? Mahendra: These nodes offer a range of advantages for specific use cases. Firstly, for specialized workloads, leveraging the compute service allows you to configure compute instances with shapes and image combination that may not be available for managed nodes or virtual nodes. This includes options like GPU shapes for hardware accelerated workloads or high frequency processor cores for demanding high-performance computing tasks. Secondly, if you require complete control over your compute instance configuration, self-managed nodes are the ideal choice. This gives you the flexibility to tailor each node to your specific requirements. Additionally, self-managed nodes are particularly well suited for Oracle Cloud Infrastructure cluster networks. These nodes provide high bandwidth, low latency RDMA connectivity, making them a preferred option for certain networking setups. Lastly, the use of compute instance pools with self-managed nodes enables the creation of infrastructure for handling complex distributed computing tasks. This can greatly enhance the efficiency of your Kubernetes environment. Consider these points carefully to determine the optimal use of OKE self-managed nodes in your deployments. 03:30 Lois: What do we need to consider before creating a self-managed node and integrating it into a cluster? Mahendra: There are two crucial aspects to address. Firstly, you need to confirm that the cluster to which you plan to add a self-managed node is configured appropriately. Secondly, it's essential to choose the right image for the compute instance hosting the self-managed node. 03:53 Nikita: Can you dive a little deeper into these prerequisites? Mahendra: To successfully integrate a self-managed node into your cluster, you must ensure that the cluster is an enhanced cluster. This is a crucial prerequisite for the addition of self-managed nodes. The flannel CNI plugin for pod networking should be utilized, not the VCN-native pod networking CNI plugin. This ensures optimal pod networking for your self-managed nodes. The control plane nodes of the cluster must be running Kubernetes version 1.25 or later. This is essential for compatibility and optimal performance. Lastly, maintain compatibility between the Kubernetes version on control plane nodes and worker nodes with a maximum allowable difference of two minor versions. This ensures a smooth and stable operation of your Kubernetes environment. Keep these cluster requirements in mind as you prepare to add self-managed nodes to your OKE cluster. 04:55 Lois: What about the image requirements when creating self-managed nodes? Mahendra: Choose either Oracle Linux 7 or Oracle Linux 8 image, for your self-managed nodes. Ensure that the selected image has a release date of March 28, 2023 or later. Obtain the image OCID, also known as Oracle Cloud Identifier, from the respective sources. When specifying an image, be mindful of the Kubernetes version it contains. It's your responsibility to select an image with a Kubernetes version that aligns with the Kubernetes version skew support policy. Keep in mind that the Container Engine for Kubernetes does not automatically check the compatibility. So it's up to you to ensure harmony between the Kubernetes version on the self-managed node and the cluster's control plane nodes. These considerations will help you make informed choices when configuring images for your self-managed nodes. 05:57 Nikita: I really like the flexibility and customization OKE self-managed nodes offer. Now I want to switch gears a little and ask you about OCI Service Operator for Kubernetes. Can you tell us a bit about it? Mahendra: OCI Service Operator for Kubernetes is an open-source Kubernetes add-on that transforms the way we manage and connect OCI resources within our Kubernetes clusters. This powerful operator enables you to effortlessly create, configure, and interact with OCI resources directly from your Kubernetes environment, eliminating the need for constant navigation between the Oracle Cloud Infrastructure Console, CLI, or other tools. With the OCI Service Operator, you can seamlessly leverage kubectl to call the operator framework APIs, providing a streamlined and efficient workflow. 06:53 Lois: On what framework is the OCI Service Operator built? Mahendra: OCI Service Operator for Kubernetes is built using the open-source Operator Framework toolkit. The Operator Framework manages Kubernetes-native applications called operators in an effective, automated, and scalable way. The Operator Framework comprises essential components like Operator SDK. This leverages the Kubernetes controller-runtime library, providing high-level APIs and abstractions for writing operational logic. Additionally, it offers tools for scaffolding and code generation. 07:35 Do you want to stay ahead of the curve in the ever-evolving AI landscape? Look no further than our brand-new OCI Generative AI Professional course and certification. For a limited time only, we're offering both the course and certification for free! So, don't miss out on this exclusive opportunity to get certified on Generative AI at no cost. Act fast because this offer is valid only until July 31, 2024. Visit https://education.oracle.com/genai to get started. That's https://education.oracle.com/genai. 08:14 Nikita: Welcome back! Mahendra, are there any other components within OCI Service Operator to manage Kubernetes deployments? Mahendra: The other essential component is Operator Lifecycle Manager, also abbreviated as OLM. OLM extends Kubernetes by introducing a declarative approach to install, manage, and upgrade operators within a cluster. The OCI Service Operator for Kubernetes is intelligently packaged as an Operator Lifecycle Manager bundle, simplifying the installation process on Kubernetes clusters. This comprehensive bundle encapsulates all necessary objects and definitions, including CRDs, RBACs, ConfigMaps, and deployments, making it effortlessly deployable on a cluster. 09:02 Lois: So much that users can take advantage of! What about OCI Service Operator's integration with other OCI services? Mahendra: One of its standout features is its seamless integration with a range of OCI services. The first one is Autonomous Database, specifically tailored for transaction processing, mixed workloads, analytics, and data warehousing. Enjoy automated patching, upgrades, and tuning, allowing routine maintenance tasks to be performed without human intervention. The next on the list is MySQL HeatWave, a fully-managed Database Service designed for developing and deploying secure cloud-native applications using widely adopted MySQL open-source database. Third on the list is OCI Streaming service. Experience a fully managed, scalable, and durable solution for ingesting and consuming high-volume data streams in real time. Next is Service Mesh. This service offers a set of capabilities to facilitate communication among microservices within a cloud-native application. The communication is centrally managed and secured, ensuring a smooth and secure interaction. The OCI Service Operator for Kubernetes serves as a versatile bridge, seamlessly connecting your Kubernetes clusters with these powerful Oracle Cloud Infrastructure services. 10:31 Nikita: That's awesome! I've also heard about Ingress Controllers. Can you tell us what they are? Mahendra: A Kubernetes Ingress Controller serves as the enforcer of rules defined in a Kubernetes Ingress. Its primary role is to manage, load balance, and route incoming traffic to specific service pods residing on worker nodes within the cluster. At the heart of this process is the Kubernetes Ingress Resource. Think of it as a blueprint, a rich configuration holding routing rules and options, specifically crafted for handling HTTP and HTTPS traffic. It serves as a powerful orchestrator for managing external communication with services inside the cluster. 11:15 Lois: Mahendra, how do Ingress Controllers bring about efficiency? Mahendra: Efficiency comes with consolidation. With a single ingress resource, you can neatly gather routing rules for multiple services. This eliminates the need to create a Kubernetes service of type LoadBalancer for each service seeking external or private network traffic. The OCI native ingress controller is a powerhouse. It crafts an OCI Flexible Load Balancer, your gateway to efficient request handling. The OCI native ingress controller seamlessly adapts to changes in routing rules with real-time updates. 11:53 Nikita: And what about integration with an OKE cluster? Mahendra: Absolutely. It harmonizes with the cluster for streamlined traffic management. Operating as a single pod on a randomly selected worker node, it ensures a balanced workload distribution. 12:08 Lois: Moving on, let's talk about running applications on ARM-based nodes and GPU nodes. We'll start with ARM-based nodes. Mahendra: Typically, developers use ARM-based worker nodes in Kubernetes cluster to develop and test applications. Selecting the right infrastructure is crucial for optimal performance. 12:28 Nikita: What kind of options do developers have when running applications on ARM-based nodes? Mahendra: When it comes to running applications on ARM-based nodes, you have a range of options at your fingertips. First up, consider the choice between ARM-based bare metal shapes and flexible VM shapes. Each comes with its own unique advantages. Now, let's talk about the heart of it all, the Ampere A1 Compute instances. These instances are driven by the cutting edge Ampere Altra processor, ensuring high performance and efficiency for your workloads. You must specify the ARM-based node pool shapes during cluster or node pool creation, whether you choose to navigate through the user-friendly console, leverage the flexibility of the API, or command with precision through the CLI, the process remains seamless. 13:23 Lois: Can you define pods to run exclusively on ARM-based nodes within a heterogeneous cluster setup? Mahendra: In scenarios where a cluster comprises node pools with ARM-based shapes alongside other shapes, such as AMD64, you can employ a powerful tool called node selector in the pod specification. This allows you to precisely dictate that an application should exclusively run on ARM-based worker nodes, ensuring your workloads aligns with the desired architecture. 13:55 Nikita: And before we end this episode, can you explain why developers must run applications on GPU nodes? Mahendra: Originally designed for graphics manipulations, GPUs prove highly efficient in parallel data processing. This makes them a top choice for deploying data-intensive applications. Our GPU nodes utilize cutting edge NVIDIA graphics cards ensuring efficient and powerful data processing. Seamless access to this computing prowess is made possible through CUDA libraries. To ensure smooth integration, be sure to select a GPU shape and opt for an Oracle Linux GPU image preloaded with the essential CUDA libraries. CUDA here is Compute Unified Device Architecture, which is a parallel computing platform and application-programming interface model created by NVIDIA. It allows developers to use NVIDIA graphics-processing units for general-purpose processing, rather than just rendering graphics. 14:57 Nikita: Thank you, Mahendra, for another insightful session.

Want to gain insights into how virtual nodes provide a serverless Kubernetes experience? Join hosts Lois Houston and Nikita Abraham, along with senior OCI instructor Mahendra Mehra, as they compare managed nodes and virtual nodes. Continuing from the previous episode, they explore how virtual nodes enhance Kubernetes deployments in Oracle Cloud Infrastructure. OCI Container Engine for Kubernetes Specialist: https://mylearn.oracle.com/ou/course/oci-container-engine-for-kubernetes-specialist/134971/210836 Oracle University Learning Community: https://education.oracle.com/ou-community LinkedIn: https://www.linkedin.com/showcase/oracle-university/ X (formerly Twitter): https://twitter.com/Oracle_Edu Special thanks to Arijit Ghosh, David Wright, Radhika Banka, and the OU Studio Team for helping us create this episode. -------------------------------------------------------- Episode Transcript: 00:00 Welcome to the Oracle University Podcast, the first stop on your cloud journey. During this series of informative podcasts, we'll bring you foundational training on the most popular Oracle technologies. Let's get started! 00:25 Lois: Welcome to the Oracle University Podcast! I'm Lois Houston, Director of Innovation Programs with Oracle University, and with me is Nikita Abraham, Principal Technical Editor. Nikita: Hey everyone! In our last episode, we examined OCI Container Engine for Kubernetes, including its key features and benefits. Lois: Yeah, that was an interesting one. Today, we're going to discuss virtual nodes and their role in enhancing Kubernetes deployments in Oracle Cloud Infrastructure. Nikita: We're going to compare virtual nodes and managed nodes, and look at their differences and advantages. To take us through all this, we have Mahendra Mehra with us. Mahendra is a senior OCI instructor with Oracle University. 01:09 Lois: Hi Mahendra! From our discussion last week, we know that when creating a node pool with Container Engine for Kubernetes, we have the option of specifying the type of Oracle nodes as either managed nodes or virtual nodes. But I'm sure there are some key differences in the features supported by each type, right? Mahendra: The primary point of differentiation between virtual nodes and managed nodes is in their management approach. When it comes to managed nodes, users are responsible for managing the nodes. They have the flexibility to configure them to meet the specific requirements. Users are also responsible for upgrading Kubernetes on managed nodes and for managing cluster capacity. You can create managed nodes and node pools in both basic clusters and enhanced clusters, whereas in virtual nodes, virtual nodes provide a serverless Kubernetes, experience, enabling users to run containerized applications at scale. The Kubernetes software is upgraded and security patches are applied while respecting application's availability requirements. You can only create virtual nodes and virtual node pools in enhanced clusters. 02:17 Nikita: What about differences in terms of resource allocation? Are there any differences we should be aware of? Mahendra: When it comes to managed nodes, the resource allocation is at the node pool level and the users specify CPU and memory resource requirements for a given node pool. In the virtual nodes, the resource allocation is done at the pod level, where you can specify the CPU and memory resource requirements, but this time, as requests and limits in the pod specification. 02:45 Lois: What about differences in the approach to load balancing? Mahendra: When it comes to managed nodes, load balancing is between the worker nodes, whereas in virtual nodes, load balancing is between pods. Also, load balancer security list management is never enabled, and you always must manually configure security rules. When using virtual nodes, load balances distribute traffic among pods' IP addresses and then assign node port. 03:12 Lois: And when it comes to pod networking? Mahendra: Under managed nodes, both the VCN-Native Pod Networking CNI plugin and the flannel CNI plugin are supported. When it comes to virtual nodes, only VCN-Native Pod Networking is supported. Also, only one VNIC is attached to each virtual node. Remember, IP addresses are not pre-allocated before pods are created. And the VCN-Native Pod Networking CNI plugin is not shown as running in the kube-system namespace. Pod subnet route tables must have route rules defined for a NAT gateway and a service gateway. 03:48 Nikita: OK… I have a question, Mahendra. When it comes to scaling Kubernetes clusters and node pools, can users adjust the cluster capacity in response to their changing requirements? Mahendra: When it comes to managed nodes, customers can scale the cluster and node pool up and down by changing the number of managed node pools and nodes respectively. They also have an option to enable autoscaling to automatically scale managed node pools and pods. When it comes to virtual nodes, operational overhead of cluster capacity management is handled for you by OCI. A virtual node pool scales automatically and can support up to 1000 pods per virtual node. Users also have an option to increase the number of virtual node pools or virtual nodes to scale up the cluster or node pool respectively. 04:37 Lois: And what about the pricing for each? Mahendra: Under managed nodes, you pay for the compute instances that execute applications, whereas under virtual nodes, you pay for the exact compute resources consumed by each Kubernetes pod. 04:55 Do you want to stay ahead of the curve in the ever-evolving AI landscape? Look no further than our brand-new OCI Generative AI Professional course and certification. For a limited time only, we're offering both the course and certification for free! So, don't miss out on this exclusive opportunity to get certified on Generative AI at no cost. Act fast because this offer is valid only until July 31, 2024. Visit https://education.oracle.com/genai to get started. That's https://education.oracle.com/genai. 05:34 Nikita: Welcome back! We were just discussing how when you have to choose between virtual nodes and managed nodes for your Kubernetes cluster, you need to consider several key points of differentiation, like the management approach, resource allocation, load balancing, pod networking, scaling, and pricing. Lois: Yeah, it's important to understand the benefits and drawbacks of each approach to make informed decisions. Mahendra, now let's talk about the prerequisites to configure clusters with virtual nodes and the IAM policies that are required to use virtual nodes. Mahendra: Before you can use virtual nodes, you always have to set up at least one IAM policy, which is required in all circumstances by both tenancy administrators and non-administrator users. This basically means, to create and use clusters with virtual nodes and virtual node pools, you must endorse Container Engine for Kubernetes service to allow virtual nodes to create container instances in the Container Engine for Kubernetes service tenancy with a VNIC connected to a subnet of a VCN in your tenancy. All you need to do is create a policy in the root compartment with policy statements from the official documentation page. You will find them under the Working with Virtual Nodes section within the Container Engine topic. 06:55 Lois: Mahendra, how do you create and configure virtual nodes and virtual node pools? Mahendra: Creating virtual nodes is a pivotal step and it involves setting up a virtual node pool in a new cluster. This is exclusively applicable to enhanced clusters. You can initiate this process using the console, the CLI, or the API. Configuring your virtual node pools involves defining critical parameters. Firstly, we have the node count. This represents the number of virtual nodes you wish to create within your virtual node pool. These nodes will be strategically placed in the availability domains that you specify. Now, it's important to carefully consider the placement of these nodes. You can distribute them across different availability domains, ensuring high availability for your applications. Additionally, you have the option to place these nodes in a regional subnet, which is the recommended approach for optimal performance. 07:53 Nikita: Isn't the pod shape another important parameter? Can you tell us a bit about it? Mahendra: Pod shape refers to the type of shape you want for pods running on your virtual nodes within the virtual node pool. The pod shape is crucial as it determines the processor type on which you want your pods to run. It is important to note that only shapes available in your tenancy and supported by Container Engine for Kubernetes will be shown. So choose a shape that aligns with the requirements of your applications and services. A noteworthy point is that you explicitly specify the CPU and memory resource requirements for virtual nodes in the pod specification file. This ensures that your virtual nodes have the necessary resources to handle the workloads of your applications. Precision in specifying these requirements is key to achieving optimal performance. 08:49 Lois: What is the network setup for virtual nodes? Mahendra: The pod running on virtual nodes utilize VCN-native pod networking, and it's crucial to specify how these pods in the node pool communicate with each other. This involves setting up a pod subnet, which is a regional subnet configured specially to host pods. The pod subnet you specify for virtual nodes must be private. Oracle recommends that the pod subnet and the virtual node subnets are the same. In addition to subnet configurations, you have the option to use security rules in network security group to control access to the pod subnet. This involves defining security rules within one or more NSGs that you specify with a maximum limit of five network security groups. Also, it is worth noting that using network security group is recommended over using security list. Now, let's shift our focus to virtual node communication. For this, you will configure a virtual node subnet. This subnet can be either a regional subnet, which is recommended, or an availability domain-specific subnet. And it's designed to host your virtual nodes. 10:02 Nikita: What are some key considerations for virtual node subnets? Mahendra: If you've specified load balancer subnets, ensure that the virtual node subnets are different. As with pod communication, Oracle recommends that the pod subnet and the virtual node subnet are the same, with the added condition that the virtual node subnet must be private. 10:23 Lois: Mahendra, can you take us through the fundamental tasks involved in managing virtual nodes and virtual node pools? Mahendra: Whether you're creating a new enhanced cluster using the Console, or looking to scale up an existing one, the creation process is versatile. Creating virtual nodes involves establishing a virtual node pool. Virtual nodes can only be created within enhanced clusters. Listing virtual nodes task offers visibility into virtual nodes within a virtual node pool. Whether you prefer Console, CLI, or the API, you have the flexibility to choose the method that suits your workflow best. For a comprehensive understanding of your virtual node pools, navigate to the Cluster List page, and click on the name of the cluster. This will unveil the specifics of the virtual node pool you are interested in. Now let's talk about updating virtual node pools. Whether your initiating a new enhanced cluster, or expanding an existing one, the update process ensures your cluster aligns with your evolving requirements. You can easily update the virtual node pool's name for clarity. You can also dynamically change the number of virtual nodes to meet the workload demands, and you can fine tune the Node Placement using options like Availability Domain and Fault Domain settings. Moving on to an essential aspect of node pool management, that is deletion. It's crucial to understand that deleting a node pool is a permanent action. Once deleted, the node pool cannot be recovered. 12:04 Lois: Before we wrap up, Mahendra, can you talk about the critical factors when allocating CPU, memory, and storage resources to pods provisioned by virtual nodes within your OKE cluster? Mahendra: To ensure optimal performance, OKE calculates CPU and memory allocations at the pod level, a distinctive feature when using virtual nodes. This approach stands in contrast to the traditional worker node-level allocation. The allocation process takes into account several factors. First one is the CPU and memory requests and limits. These are specified for each container in the pod spec file, if present. Secondly, number of containers in the pod. The total number of containers impacts the overall resource requirements. And kube-proxy and container runtime requirements. A small but essential consideration taking up 0.25 GB of memory and negligible CPU. Pod CPU and memory requests must meet a minimum of 0.125 OCPUs and 0.5 GB of memory. 13:12 Nikita: Thank you, Mahendra, for this really insightful session.

During this series of informative podcasts, we'll bring you foundational training on the most popular Oracle technologies. Let's get started! 00:26 Nikita: Hello and welcome to the Oracle University Podcast. I'm Nikita Abraham, Principal Technical Editor with Oracle University, and I'm joined by Lois Houston, Director of Innovation Programs. Lois: Hi there! This is our second episode on OCI Container Engine for Kubernetes, and today we're going to spend time discussing container registries with our colleague and senior OCI instructor, Mahendra Mehra. Nikita: We'll talk about how you can become proficient in managing Oracle Cloud Infrastructure Registry, a vital component in your container workflow. 00:58 Lois: Hi Mahendra, can you explain what Oracle Cloud Infrastructure Registry, or OCIR, is and how it simplifies the container image management process? Mahendra: OCIR is an Oracle-managed registry designed to simplify the development-to-production workflow for developers. It offers a range of functionalities, serving as a private docker registry for internal use where developers can easily store, share, and manage container images. The strength of OCIR lies in its high available and scalable architecture. Leveraging OCI to ensure reliable deployment of applications, developers can use OCIR not only as a private registry but also as a public registry, facilitating the pulling of images from public repositories for users with internet access. 01:55 Lois: But what sets OCIR apart? Mahendra: What sets OCIR apart is its compliance with the Open Container Initiative standards, allowing the storage of container images conforming to the OCI specifications. It goes a step further by supporting manifest lists, sometimes known as multi-architecture images, accommodating diverse architectures like ARM and AMD64. Additionally, OCIR extends its support to Helm charts. Security is a priority with OCIR, offering private access through a service gateway. This means that OCI resources within a VCN in the same region can securely access OCIR without exposing them to the public internet. 02:46 Nikita: OK. What are some other key advantages of OCIR? Mahendra: Firstly, OCIR seamlessly integrates with the Container Engine for Kubernetes, ensuring a cohesive container management experience. In terms of security, OCIR provides flexibility by allowing registries to be either private or public, giving administrators control over accessibility. It is intricately integrated with IAM, offering straightforward authentication through OCI Identity. Another notable benefit is regional availability. You can efficiently pull container images from the same region as your deployments. For high-performance, availability, and low-latency image operations, OCIR leverages the robust infrastructure of OCI, enhancing the overall reliability of image push and pull operations. OCIR ensures anywhere access, allowing you to utilize container CLI for image operations from various locations, be it on the cloud, on-premises, or even from personal laptops. 03:57 Lois: I believe OCIR has repository quotas? Is there a cap on them? Mahendra: In each enabled region for your tenancy, you can establish up to 500 repositories with a cumulative storage limit of 500 GB. Each repository is capable of holding up to 100,000 images. Importantly, charges apply only for stored images. 04:21 Nikita: That's good to know, Mahendra. I want to move on to basic container registry concepts. Maybe we can start with what an image is. Mahendra: Image is basically a read-only template with instructions for creating a container. It holds the application that you want to run as a container, along with any dependencies that are required. Container registry is an Open Container Initiative-compliant registry. As a result, you can store any artifacts that conform to Open Container Initiative specifications, such as Docker images, manifest lists, sometimes also known as multi-architecture images, and Helm charts. 05:02 Lois: And what's a repository then? Mahendra: It's a meaningfully named collection of related images which are grouped together for convenience in a container registry. There are different versions of the same source image, which are grouped together into the same repository. You can have multiple images stored under this repository. The only thing that you need to keep changing is the image version. Every image version is given a tag. And the tag uniquely identifies the image. 05:33 Lois: Is it possible to make the repository public or private? Mahendra: Depending upon your need, a repository can be made private or public. One important thing to note is that the user needs to have an OCI username and authentication token before being able to push/pull an image from the OCIR. 05:52 Nikita: There are so many terms that you come across when working with repositories and container registry, right? Could you take us through them and explain how they relate to each other? I've heard of the region key and tenancy namespace. Mahendra: The region key identifies the container registry region that you are using. A tenancy namespace is an auto-generated random and immutable string of alphanumeric characters. The tenancy namespace can be retrieved from the value of your object storage namespace field. Repository name is the name of a repository in container registry, to and from which you can push and pull images. Repository names can include one or more slash characters and are unique across all the compartments in the entire tenancy. You should note that although a repository name can include slash characters, the slash does not represent a hierarchical directory structure. It is simply one character in the string of characters. As a convenience, you might choose to start the name of different repositories with the same string. A registry identifier is the combination of your container registry region key and the tenancy namespace. 07:07 Lois: What about an image tag and an image path? How do they differ from each other? Mahendra: A tag or an image tag is a string used to refer to a particular image in a known registry. The term "image name" is sometimes used as a shorthand way to refer to a particular image in a particular repository. A tag can be a numerical value or it can be a string. An image path is a fully qualified path to a particular image in a registry. It extends the repository path by adding tags associated with the image. 07:46 Do you want to stay ahead of the curve in the ever-evolving AI landscape? Look no further than our brand-new OCI Generative AI Professional course and certification. For a limited time only, we're offering both the course and certification for free.

Visit https://education.oracle.com/genai to get started. That's https://education.oracle.com/genai. 08:24 Nikita: Welcome back! Mahendra, from what you've told us, OCIR seems like such a pivotal tool for modern containerized workflows, with its seamless integration, robust security measures, regional accessibility, efficient image management. So, how do we actually manage OCIR? Mahendra: Managing OCIR can be done in three ways. Starting with managing the repository itself, followed by managing the images within the repository, and, last but not the least, managing the overall security of your repository alongside the images. 08:58 Nikita: Can we dive into each of these approaches in a little more detail? How does managing the repository itself work? Mahendra: You can create an empty repository in a compartment and give it a name that's unique across all the compartments in the entire tenancy. There is a limit to the number of repositories you can have in a given region in a tenancy. So, when you no longer need a repository, it makes sense to delete it from the Oracle Cloud Infrastructure registry. Make a note that when you delete a repository, it can take up to 48 hours for the deletion to take effect and for the storage to actually be released. When you create a new repository in Oracle Cloud Infrastructure Registry, you specify the compartment in which you want to create it. Having created the repository in one compartment, you can subsequently move it to a different compartment. The reasons can be many. It can be to change the users who are authorized to use the repository or to change how the billing for a repository is charged. 09:52 Lois: OK. And what about managing images within the repository? Mahendra: You can view the images stored on OCIR using the OCI Console or using Docker images command from your Docker client after logging in to the OCIR repo. To push an image, you first used the Docker tag command to create a copy of the local source image as a new image. As a name for the new image, you specify the fully-qualified path to the target location in your container registry where you want to push the image, including the name of a repository. In order to pull an image, you must be logged in into the OCIR registry using the auth token and use the Docker pull command followed by a fully-qualified name of the image you wish to download on your Docker client. 10:36 Nikita: What happens when you no longer need an old image or you simply want to clean up the list of image tags in a repository? Mahendra: You can delete images from the Oracle Cloud Infrastructure Registry. You can undelete an image you've previously deleted for up to 48 hours after you deleted it. After that time, the image is permanently removed from the container registry. You can set up image retention policies to automatically delete images that meet particular selection criteria. 11:02 Lois: What sort of selection criteria? Mahendra: Criterias can be images that have not been pulled for a certain number of days or images that have not been tagged for a certain number of days. It can also be images that have not been given particular Docker tags specified as exempt from the automatic deletion. There's an hourly process that checks images against the selection criteria, and any that meet the selection criteria are automatically deleted. In each region in a tenancy, there's a global image retention policy. The default criteria of the policy is to retain all images so that no images are automatically deleted. However, you can change the global image retention policy so that the images are deleted if they meet certain criteria that you specify. A region's global image retention policy applies to all the repository within that region unless it is explicitly overridden by one or more custom image retention policies. Only one custom image retention policy at a time can be applied to a repository. If a repository has already been added to a custom retention policy and you want to add repository to a different custom retention policy, you have to remove the policy from the first retention policy before adding it to the second one. 12:15 Lois: Mahendra, what should we keep in mind when we're dealing with the global image retention policy? Mahendra: The global image retention policy are specific to a particular region. To delete images consistently in different regions in your tenancy, you need to set up image retention policies in each region with identical selection criteria. If you want to prevent images from being deleted on the basis of Docker tags they've been given, you need to specify those tags as exempt in a comma-separated list. When you want to clean up the list of images in a repository without actually deleting the images, you can remove the tags from the images in OCIR. Removing images is referred to as untagging. 12:53 Nikita: OK…and the last approach was managing the overall security of your repository alongside the images, right? Mahendra: While managing security, you are given fine grained control over the operations that users are allowed to perform on repositories within the Container Registry. Using the concept of users and groups, you can control repository access by setting up identity access management policies at the tenancy and at the compartment level. You can write policies to allow inspect, read, use, and manage operations on the repository based on the requirements. You can set up Oracle Cloud Infrastructure Registry to scan images in a repository for security vulnerabilities published in the publicly available common vulnerabilities and exposure databases. To perform image scanning, container registry makes use of the Oracle Cloud Infrastructure vulnerability-scanning service and vulnerability scanning REST API. 13:46 Nikita: What do I need to have in place before I can push and pull Docker images to and from Oracle Cloud Infrastructure Registry? Mahendra: The first thing is, your tenancy must be subscribed to one or more of the regions in which the container registry is available. You can check the same within the Oracle documentation. The next thing is, you need to have access to the Docker command line interface to push and pull images on your local machine. The third thing is, users must belong to a group to which a policy grants the appropriate permission or belong to a tenancies administrator group, which by default have access permissions on the container registry. Lastly, user must already have an Oracle Cloud Infrastructure username and an authentication token, which enables them to perform operations on the container registry. 14:29 Lois: Thank you, Mahendra, for sharing your insights on OCIR with us.

Autonomous Database on Dedicated Infrastructure

Play Episode Listen Later Jan 9, 2024 26:36

The Oracle Autonomous Database Dedicated deployment is a good choice for customers who want to implement a private database cloud in their own dedicated Exadata infrastructure. That dedicated infrastructure can either be in the Oracle Public Cloud or in the customer's own data center via Oracle Exadata Cloud@Customer. In a dedicated environment, the Exadata infrastructure is entirely dedicated to the subscribing customer, isolated from other cloud tenants, with no shared processor, storage, and memory resource. In this episode, hosts Lois Houston and Nikita Abraham speak with Oracle Database experts about how Autonomous Database Dedicated offers greater control of the software and infrastructure life cycle, customizable policies for separation of database workload, software update schedules and versioning, workload consolidation, availability policies, and much more. Oracle MyLearn: https://mylearn.oracle.com/ Oracle University Learning Community: https://education.oracle.com/ou-community LinkedIn: https://www.linkedin.com/showcase/oracle-university/ X (formerly Twitter): https://twitter.com/Oracle_Edu Special thanks to Arijit Ghosh, David Wright, Tamal Chatterjee, and the OU Studio Team for helping us create this episode. ------------------------------------------------------- Episode Transcript: 00:00 Welcome to the Oracle University Podcast, the first stop on your cloud journey. During this series of informative podcasts, we'll bring you foundational training on the most popular Oracle technologies. Let's get started. 00:26 Nikita: Hello and welcome to the Oracle University Podcast. I'm Nikita Abraham, Principal Technical Editor with Oracle University, and I'm joined by Lois Houston, Director of Innovation Programs. Lois: Hi there! This is our second episode on Oracle's Autonomous Database, and today we're going to spend time discussing Autonomous Database on Dedicated Infrastructure. We'll be talking with three of our colleagues: Maria Colgan, Kamryn Vinson, and Kay Malcolm. 00:53 Nikita: Maria is a Distinguished Product Manager for Oracle Database, Kamryn is a Database Product Manager, and Kay is a Senior Director of Database Product Management. Lois: Hi Maria! Thanks for joining us today. We know that Oracle Autonomous Database offers two deployment choices: serverless and dedicated Exadata infrastructure. We spoke about serverless infrastructure last week but for anyone who missed that episode, can you give us a quick recap of what it is? 01:22 Maria: With Autonomous Database Serverless, Oracle automates all aspects of the infrastructure and database management for you. That includes provisioning, configuring, monitoring, backing up, and tuning. You simply select what type of database you want, maybe a data warehouse, transaction processing, or a JSON document store, which region in the Oracle Public Cloud you want that database deployed, and the base compute and storage resources necessary. Oracle automatically takes care of everything else. Once provisioned, the database can be instantly scaled through our UI, our APIs, or automatically based on your workload needs. All scaling activities happen completely online while the database remains open for business. 02:11 Nikita: Ok, so now that we know what serverless is, let's move on to dedicated infrastructure. What can you tell us about it? Maria: Autonomous Database Dedicated allows customers to implement a private database cloud running on their own dedicated Exadata infrastructure. That dedicated infrastructure can be in Oracle's Public Cloud or in the customer's own data center via Oracle Exadata Cloud@Customer. It makes an ideal platform to consolidate multiple databases regardless of their workload type or their size. And it also allows you to offer database as a service within your enterprise. 02:50 Lois: What are the primary benefits of Autonomous Database Dedicated infrastructure? Maria: With the dedicated deployment option, you must first subscribe to Dedicated Exadata Cloud Infrastructure that is isolated from other tenants with no shared processors, memory, network, or storage resources. This infrastructure choice offers greater control of both the software and the infrastructure life cycle. Customers can specify their own policies for workload separation, software update schedules, and availability. One of the key benefits of an autonomous database is a lower total cost of ownership through more automation and operational delegation to Oracle. Remember it's a fully managed service. All database operations, such as backup, software updates, upgrades, OS maintenance, incident management, and health monitoring, will be automatically done for you by Oracle. Its maximum availability architecture protects you from any hardware failures and in the event of a full outage, the service will be automatically failed over to your standby site. Built-in application continuity ensures zero downtime during the standard software update or in the event of a failover. 04:09 Nikita: And how is this billed? Maria: Autonomous Database also has true pay-per-use billing so even when autoscale is enabled, you'll only pay for those additional resources when you use them. And we make it incredibly simple to develop on this environment with managed developer add-ons like our low code development environment, APEX, and our REST data services. This means you don't need any additional development environments in order to get started with a new application. 04:40 Lois: Ok. So, it looks like the dedicated option offers more control and customization. Maria, how do we access a dedicated database over a network? Maria: The network path is through a VCN, or Virtual Cloud Network, and the subnet that's defined by the Exadata infrastructure hosting the database. By default, this subnet is defined as private, meaning, there's no public internet access to those databases. This ensures only your company can access your Exadata infrastructure and your databases. Autonomous Database Dedicated can also take advantage of network services provided by OCI, including subnets or VCN peering, as well as connections to on-prem databases through the IP secure VPN and FastConnect dedicated corporate network connections. 05:33 Maria: You can also take advantage of the Oracle Microsoft partnership that enables customers to connect their Oracle Cloud Infrastructure resources and Microsoft Azure resources through a dedicated private connection. However, for some customers, a move to the public cloud is just not possible. Perhaps it's due to industry regulations, performance concerns, or integration with legacy on-prem applications. For these types of customers, Exadata Cloud@Customer should meet their requirements for strict data sovereignty and security by delivering high-performance Exadata Cloud Services capabilities in their data center behind their own firewall. 06:16 Nikita: What are the benefits of Autonomous Database on Exadata Cloud@Customer? How's it different? Maria: Autonomous Database on Exadata Cloud@Customer provides the same service as Autonomous Database Dedicated in the public cloud. So you get the same simplicity, agility, and performance, and elasticity that you get in the cloud. But it also provides a very fast and simple transition to an autonomous cloud because you can easily migrate on-prem databases to Exadata Cloud@Customer. Once the database is migrated, any existing applications can simply reconnect to that new database and run without any application changes being needed. And the data will leave your data center, so making it a very safe way to adopt a cloud model. 07:04 Lois: So, how do we manage communication to and from the public cloud? Maria: Each Cloud@Customer rack includes two local control plane servers to manage the communication to and from the public cloud. The local control plane acts on behalf of requests from the public cloud, keeping communications consolidated and secure. Platform control plane commands are sent to the Exadata Cloud@Customer system through a dedicated WebSocket secure tunnel. Oracle Cloud operations staff use that same tunnel to monitor the autonomous database on Exadata Cloud@Customer both for maintenance and for troubleshooting. The two remote, control plane servers installed in the Exadata Cloud@Customer rack host that secure tunnel endpoint and act as a gateway for access to the infrastructure. They also host components that orchestrate the cloud automation, aggregates and routes telemetry messages from the Exadata Cloud@Customer platform to the Oracle Support Service infrastructure. And they also host images for server patching. 08:13 Maria: The Exadata Database Server is connected to the customer-managed switches via either 10 gigabit or 25 gigabit Ethernet. Customers have access to the customer Virtual Machine, or VM, via a pair of layer 2 network connections that are implemented as Virtual Network Interface Cards, or vNICs. They're also tagged VLAN. The physical network connections are implemented for high availability in an active standby configuration. Autonomous Database on Exadata Cloud@Customer provides the best of both worlds-- all of the automation including patching, backing up, scaling, and management of a database that you get with a cloud service, but without the data ever leaving the customer's data center. 09:01 Nikita: That's interesting. And, what happens if a dedicated database loses network connectivity to the OCI control plane? Maria: In the event an autonomous database on Exadata Cloud@Customer loses network connectivity to the OCI control plane, the Autonomous Database will actually continue to be available for your applications. And operations such as backups and autoscaling will not be impacted in that loss of network connectivity. However, the management and monitoring of the Autonomous Database via the OCI console and APIs as well as access by the Oracle Cloud operations team will not be available until that network is reconnected. 09:43 Maria: The capability suspended in the case of a lost network connection include, as I said, infrastructure management-- so that's the manual scaling of an Autonomous Database via the UI or our OCI CLI, or REST APIs, as well as Terraform scripts. They won't be available. Neither will the ability for Oracle Cloud ops to access and perform maintenance activities, such as patching. Nor will we be able to monitor the Oracle infrastructure during the time where the system is not connected. 10:20 Lois: That's good to know, Maria. What about data encryption and backup options? Maria: All Oracle Autonomous Databases encrypt data at REST. Data is automatically encrypted as it's written to the storage. But this encryption is transparent to authorized users and applications because the database automatically decrypts the data when it's being read from the storage. There are several options for backing up the Autonomous Database Cloud@Customer including using a Zero Data Loss Recovery Appliance, or ZDLRA. You can back it up to locally mounted NFS storage or back it up to the Oracle Public Cloud. 10:57 Nikita: I want to ask you about the typical workflow for Autonomous Database Dedicated infrastructure. What are the main steps here? Maria: In the typical workflow, the fleet administrator role performs the following steps. They provision the Exadata infrastructure by specifying its size, availability domain, and region within the Oracle Cloud. Once the hardware has been provisioned, the fleet administrator partitions the system by provisioning clusters and container databases. Then the developers, DBAs, or anyone who needs a database can provision databases within those container databases. Billing is based on the size of the Exadata infrastructure that's provisioned. So whether that's a quarter rack, half rack, or full rack. It also depends on the number of CPUs that are being consumed. Remember, it's also possible for customers to use their existing Oracle database licenses with this service to reduce the cost. 11:53 Lois: And what Exadata infrastructure models and shapes does Autonomous Database Dedicated support? Maria: That's the X7, X8, and X8M and you can get all of those in either a quarter, half, or full Exadata rack. Currently, you can create a maximum of 12 VM clusters on an Autonomous Database Dedicated infrastructure. We also advise that you limit the number of databases you provision to meet your preferred SLA. To meet the high availability SLA, we recommend a maximum of 100 databases. To meet the extreme availability SLA, we recommend a maximum of 25 databases. 12:35 Nikita: Ok, so now that I know all this, how do I actually get started with Autonomous Database on dedicated infrastructure? Maria: You need to increase your service limit to include that Exadata infrastructure and then you need to create the fleet and DBA service roles. You also need to create the necessary network model, VM clusters, and container databases for your organization. Finally, you need to provide access to the end users who want to create and use those Autonomous databases. Autonomous Database requires a subscription to that Exadata infrastructure for a minimum of 48 hours. But once subscribed, you can test out ideas and then terminate the subscription with no ongoing costs. While subscribed, you can control where you place the resources to perhaps manage latency sensitive applications. 13:29 Maria: You can also have control over patching schedules, software versions, so you can be sure that you're testing exactly what you need to. You can also migrate databases to the Autonomous Database via our export, import capabilities via the object store or through Data Pump or Golden Gate. As with any Autonomous Database, once it's provisioned, you've got full access to both autoscaling and all our cloning capabilities. 13:57 Lois: Maria, I've heard you talk about the importance of clean role separation in managing a private cloud. Can you elaborate on that, please? Maria: A successful private cloud is set up and managed using clean role separation between the fleet administration group and the developers, or DBA groups. The fleet administration group establishes the governance constraints, including things like budgeting, capacity compliance, and SLAs, according to the business structure. The physical resources are also logically grouped to align with this business structure, and then groups of users are given self-service access to the resources within these groups. So a good example of this would be that the developers and DBA groups use self-service database resources within these constraints. 14:46 Nikita: I see. So, what exactly does a fleet administrator do? Maria: Fleet administrators allocate budget by department and are responsible for the creation, monitoring, and management of the autonomous exadata infrastructure, the autonomous exadata VM clusters, and the autonomous container databases. To perform these duties, the fleet administrators must have an Oracle Cloud account or user, and that user must have permissions to manage these resources and be permitted to use network resources that need to be specified when you create these other resources. 15:24 Nikita: And what about database administrators? Maria: Database administrators create, monitor, and manage autonomous databases. They, too, need to have an Oracle Cloud account or be an Oracle Cloud user. Now, those accounts need to have the necessary permissions in order to create and access databases. They also need to be able to access autonomous backups and have permission to access the autonomous container databases, inside which these autonomous databases will be created, and have all of the necessary permissions to be able to create those databases, as I said. While creating autonomous databases, the database administrators will define and gain access to an admin user account inside the database. It's through this account that they will actually get the necessary permissions to be able to create and control database users. 16:24 Lois: How do developers fit into the picture? Maria: Database users and developers who write applications that will use or access an autonomous database don't actually need Oracle Cloud accounts. They'll actually be given the network connectivity and authorization information they need to access those databases by the database administrators. 16:45 Lois: Maria, you mentioned the various ways to manage the lifecycle of an autonomous dedicated service. Can you tell us more about that? Maria: You can manage the lifecycle of an autonomous dedicated service through the Cloud UI, Command Line Interface, through our REST APIs, or through one of the several language SDKs. The lifecycle operations that you can manage include capacity planning and setup, the provisioning and partitioning of exadata infrastructure, the provisioning and management of databases, the scaling of CPU storage and other resources, the scheduling of updates for the infrastructure, the VMs, and the database, as well as monitoring through event notifications. 17:30 Lois: And how do policies come into play? Maria: OCI allows fine-grained control over resources through the application of policies to groups. These policies are applicable to any member of the group. For Oracle Autonomous Database on dedicated infrastructure, the resources in question are autonomous exadata infrastructure, autonomous container databases, autonomous databases, and autonomous backups. Lois: Thanks so much, Maria. That was great information. 18:05 The Oracle University Learning Community is a great place for you to collaborate and learn with experts, peers, and practitioners.

So, in an Autonomous Database environment where most DBA tasks are automated, what exactly does an application DBA do? Kamryn: While Autonomous Database automates most of the repetitive tasks that DBAs perform, the application DBA will still want to monitor and diagnose databases for applications to maintain the highest performance and the greatest security possible. Tasks the application DBA performs includes operations on databases, cloning, movement, monitoring, and creating alerts. When required, the application DBA performs low-level diagnostics for application performance and looks for insights on performance and capacity trends. 19:36 Nikita: I see. And which tools do they use for these tasks? Kamryn: There are several tools at the application DBA's disposal, including Enterprise Manager, Performance Hub, and the OCI Console. For Autonomous Dedicated, all the database operations are exposed through the console UI and available through REST API calls, including provisioning, stop/start, lifecycle operations for dedicated database types, unscheduled on-demand backups and restores, CPU scaling and storage management, providing connectivity information, including wallets, scheduling updates. 20:17 Lois: So, Kamryn, what tools can DBAs use for deeper exploration? Kamryn: For deeper exploration of the databases themselves, Autonomous Database DBAs can use SQL Developer Web, Performance Hub, and Enterprise Manager. 20:31 Nikita: Let's bring Kay into the conversation. Hi Kay! With Autonomous Database Dedicated, I've heard that customers have more control over patching. Can you tell us a little more about that? Kay: With Autonomous Database Dedicated, customers get to determine the update or patching schedule if they wish. Oracle automatically manages all patching activity, but with the ADB-Dedicated service, customers have the option of customizing the patching schedule. You can specify which month in every quarter you want, which week in that month, which day in that month, and which patching window within that day. You can also dynamically change the scheduled patching date and time for a specific database if the originally scheduled time becomes inconvenient. 21:22 Lois: That's great! So, how often are updates published, and what options do customers have when it comes to applying these updates? Kay: Every quarter, updates are published to the console, and OCI notifications are sent out. ADB-Dedicated allows for greater control over updates by allowing you to choose to apply the current update or stay with the previous version and skip to the next release. And the latest update can be applied immediately. This provides fleet administrators with the option to maintain test and production systems at different patch levels. A fleet administrator or a database admin sets up the software version policy at the Autonomous Container Database level during provisioning, although the defaults can be modified at any time for an existing Autonomous Container Database. At the bottom of the Autonomous Exadata Infrastructure provisioning screen, you will see a Configure the Automatic Maintenance section, where you should click the Modify Schedule. 22:34 Nikita: What happens if a customer doesn't customize their patching schedule? Kay: If you do not customize a schedule, it behaves like Autonomous Serverless, and Oracle will set a schedule for you. ADB-Dedicated customers get to choose the patching schedule that fits their business. 22:52 Lois: Back to you, Kamryn, I know a bit about Transparent Data Encryption, but I'm curious to learn more. Can you tell me what it does and how it helps protect data? Kamryn: Transparent Data Encryption, TDE, enables you to encrypt sensitive data that you store in tables and tablespaces. After the data is encrypted, this data is transparently decrypted for authorized users or applications when they access this data. TDE helps protect data stored on media, also called data at rest. If the storage media or data file is stolen, Oracle database uses authentication, authorization, and auditing mechanisms to secure data in the database, but not in the operating system data files where data is stored. To protect these data files, Oracle database provides TDE. 23:45 Nikita: That sounds important for data security. So, how does TDE protect data files? Kamryn: TDE encrypts sensitive data stored in data files. To prevent unauthorized decryption, TDE stores the encryption keys in a security module external to the database called a keystore. You can configure Oracle Key Vault as part of the TDE implementation. This enables you to centrally manage TDE key stores, called TDE wallets, in Oracle Key Vault in your enterprise. For example, you can upload a software keystore to Oracle Key Vault and then make the contents of this keystore available to other TDE-enabled databases. 24:28 Lois: What about Oracle Autonomous Database? How does it handle encryption? Kamryn: Oracle Autonomous Database uses always-on encryption that protects data at rest and in transit. All data stored in Oracle Cloud and network communication with Oracle Cloud is encrypted by default. Encryption cannot be turned off. By default, Oracle Autonomous Database creates and manages all the master encryption keys used to protect your data, storing them in a secure PKCS 12 keystore on the same Exadata systems where the databases reside. If your company's security policies require, Oracle Autonomous Database can instead use keys you create and manage. Customers can control key generation and rotation of the keys. 25:19 Kamryn: The Autonomous databases you create automatically use customer-managed keys because the Autonomous container database in which they are created is configured to use customer-managed keys. Thus, those users who create and manage Autonomous databases do not have to worry about configuring their databases to use customer-managed keys. 25:41 Nikita: Thank you so much, Kamryn, Kay, and Maria for taking the time to give us your insights. To learn more about provisioning Autonomous Database Dedicated resources, head over to mylearn.oracle.com and search for the Oracle Autonomous Database Administration Workshop. Lois: In our next episode, we will discuss Autonomous Database tools. Until then, this is Lois Houston… Nikita: …and Nikita Abraham signing off. 26:07 That's all for this episode of the Oracle University Podcast.

When you work with Oracle Cloud Infrastructure, one of the first steps is to set up a virtual cloud network (VCN) for your cloud resources. In this episode, Lois Houston and Nikita Abraham, along with Rohit Rahi, discuss Oracle's Virtual Cloud Network, VCN routing, and security. Oracle MyLearn: https://mylearn.oracle.com/ Oracle University Learning Community: https://education.oracle.com/ou-community X (formerly Twitter): https://twitter.com/Oracle_Edu LinkedIn: https://www.linkedin.com/showcase/oracle-university/ Special thanks to Arijit Ghosh, Kiran BR, Rashmi Panda, David Wright, the OU Podcast Team, and the OU Studio Team for helping us create this episode. --------------------------------------------------------- Episode Transcript: 00:00 Welcome to the Oracle University Podcast, the first stop on your cloud journey. During this series of informative podcasts, we'll bring you foundational training on the most popular Oracle technologies. Let's get started. 00:26 Lois: Hello and welcome to the Oracle University Podcast. I'm Lois Houston, Director of Innovation Programs with Oracle University, and with me is Nikita Abraham, Principal Technical Editor. Nikita: Hi everyone. We hope you've been enjoying these last few weeks as we've been revisiting our most popular episodes of the year. 00:47 Lois: Today's episode is the fourth of six we'll have in this series and it's a throwback to a conversation with Rohit Rahi, our Vice President of CSS OU Cloud Delivery, talking about Networking in OCI. We began by asking Rohit to explain what a Virtual Cloud Network is. Let's listen in. 01:06 Rohit: At its core, it's a private software defined network you create in Oracle Cloud. It's used for secure communication. Whether instances talking to each other, instances talking to on-premises environments, or instances talking to other instances in different regions, you would use Virtual Cloud Network. It lives in an OCI region. Like we said, it's a regional service. It's highly available, massively scalable, and secure. And we take care of these things for you. So before we dive deep into the VCN and all the characteristics and all the features it has, let's look at some of the basic stuff. 01:44 Rohit: So the first thing is VCN has an address space. In this case, you see this address space is denoted in a CIDR notation. CIDR stands for classless interdomain routing. The VCN has an IP addressing range. And what that means is you have an address range. You take that range. And you can break it down into smaller networks which are called subnetworks. And these subnetworks are where you would instantiate your compute instances. 02:16 Nikita: And what can you tell us about the different mechanisms that exist inside a VCN? Rohit: So first, there is a notion of internet gateway. This is a gateway which is massively scalable, highly available, and is used for communication to anything on the internet. So if you have a web server which wants to talk to other websites on the web being able to be accessed publicly, you would use an internet gateway. So going to the internet and coming back from the internet. You also have this highly available, massively scalable router called NAT gateway. And it is used for providing NAT as a service. 02:53 Rohit: So what this means is the traffic is unidirectional. It can go from your private subnets to the internet. But users from the internet cannot use the NAT gateway to reach your instances running in a private subnet. So the idea with the NAT gateway is to enable outbound communication to the internet, but block inbound communications or connections initiated from the internet. Then we have another router which is called Service Gateway. And the idea is it lets resources in VCN access public OCI services such as object storage, but without using an internet or NAT gateway. So these are the three scenarios-- Internet gateway for internet, NAT gateway also for internet but unidirectional, and Service gateway for accessing OCI public services, which are available on the internet but accessing them in a secure manner. And then the other construct is called Dynamic Routing Gateway. This is a virtual router that provides a path for private traffic between your VCN and destinations other than the internet. 04:00 Lois: So what can these destinations be? Rohit: Well, this can be your on-premises environment. VCN uses route tables to send traffic out of the VCN to the internet, to on-premises networks, or to peered VCN, and we look at each of these scenarios. Route tables consist of a set of route rules. Each rule specifies a destination CIDR block and a route target. Think about route target as the next hop for the traffic that matches that destination CIDR block. Now, one thing to keep in mind is traffic within the VCN subnet is automatically handled by the VCN local routing. 04:44 Lois: Want to get the inside scoop on Oracle University? Head on over to the all-new Oracle University Learning Community. Attend exclusive events. Read up on the latest news. Get first-hand access to new products and stay up-to-date with upcoming certification opportunities. If you are already an Oracle MyLearn user, go to MyLearn to join the Community. You will need to log in first. If you have not yet accessed Oracle MyLearn, visit mylearn.oracle.com and create an account to get started. Join the Community today! 05:20 Nikita: Getting back to our discussion… if you have multiple networks, how do they talk to each other? Rohit: So there are two scenarios which are possible here. If the networks are within the same OCI region, they can talk to each other through a mechanism called local peering. If the two networks are in two different OCI data center regions, then you have the same concept, a similar concept, but it's a remote peering now. And instead of using local peering, now you're using the Dynamic Routing Gateways. Remember we talked about Dynamic Routing Gateways used for on-premises communication, anything which is not for internet. So this is also a use case for Dynamic Routing Gateway enabling communication between networks in different regions. 06:05 Rohit: So within VCN, you have this concept of security list. Think about security list as firewall rules associated with a subnet and applied to all instances inside the subnet. So what does it look like? The security list consists of rules that specify the type of traffic allowed in or out of the subnet. This applies to a given instance, whether it is talking with another instance in the VCN or a host outside the VCN. There's also another concept, which is called network security groups, or NSG. These are very similar construct as security list, but the key difference is these apply only to a set of virtual network interface cards in a single VCN. And another big difference here is NSGs can be the source or destination in the rules. Contrast this with the security list rules where you specify a CIDR, only a CIDR, as the source or destination. 07:06 Lois: Thanks for that, Rohit. To learn more about OCI, please visit mylearn.oracle.com, create a profile if you don't already have one, and get started learning on our free OCI Foundations training. Nikita: You can also practice what you learn in a safe environment with our hands-on labs, without the anxiety of working in a live environment. 07:27 Nikita: We hope you enjoyed that conversation. Join us next week for another throwback episode. Until then, this is Nikita Abraham... Lois: And Lois Houston, signing off! 07:37 That's all for this episode of the Oracle University Podcast.

Best ETFs in Canada - Featuring MoneySense and Ben Felix

Play Episode Listen Later Oct 25, 2022 58:02

One resource that I check out every year is MoneySense's “Best ETFs in Canada” guide. They bring on a panel of experts to find Canada's top ETFs for DIY index investors (like myself). I found this guide extremely helpful when I was first getting started in investing, and now, many years later, I still read it when it gets updated annually, just to be “in the know” of what's happening when it comes to index investing in Canada, and to stay up to date on any significant changes like the updated fees, new ETF offerings, and any changes to existing top ETFs that you and I have in our portfolios already. This podcast interview is different from you just reading the written version of the guide because we actually do a deep dive into the different ETFs that are in the guide. Definitely check out the written version of the guide as well, especially since it has some really useful tables that nicely summarize what the top ETFs are, in the different categories. But, definitely still listen to this interview as the writer of the MoneySense guide is on the show today to dive deeper into the findings, along with one of the top panellists and experts, Ben Felix from PWL Capital to provide his analysis on the different top ETFs. Questions Covered: Bryan, can you start by telling us about your background, as well as this annual initiative led by MoneySense to determine the best ETFs in Canada? Ben, can you tell us a bit about your background and the work that you do? Bryan, how does voting work among the panellists before an ETF is admitted as one of the “Top ETFs in Canada”? Bryan, there are a lot of different investing strategies out there. When you and the panellists are evaluating what the best ETFs in Canada are, what is the goal and strategy that you are all focused on and what kind of investor is this top ETFs list for? Ben, before we get into the results, what should someone do if they are holding a past ‘top pick', and now they no longer see that pick on this year's list? In other words, when should we actually really consider swapping to a completely different ETF if we already have a good diversified index portfolio in place? Ben, when it comes to switching from one ETF to another, what are the trading costs that we need to be aware of? The $5-$10 trading commissions are the one I think most people are familiar with, but what about the bid/ask spread, how much of a cost impact does that have? And are there any other costs we need to be aware of, when for example someone is tempted to switch ETFs because let's say, a top pick for this year has a slightly lower MER? Top Canadian ETFs: Alright, let's take a look at the top Canadian, total market, index ETFs that give you exposure to the Canadian stock market. I noticed that all three of the top picks have the same management fee. We have BMO with ZCN, Vanguard with VCN, and iShares with XIC. Ben, BMO's ZCN and iShares' XIC look almost identical to me. Are there any key differences between these two that we should be aware of? The other thing that jumped out at me is that Vanguard's VCN has fewer holdings, 181 vs 240 compared to the iShares and BMO ETFs. Would this be considered a concern by implying that the Vanguard ETF is less diversified than the BMO and iShares versions? i.e. Why would you go with Vanguard when you can get more holdings and be more diversified with XIC or ZCN? Bryan, another top pick in this category is Horizons' HXT ETF, which covers the S&P/TSX 60. You mention in the article that “it's tax-efficient; and has a rock-bottom 0.04% fee after the rebate, until at least Dec. 31, 2022”. Can you explain what this rebate is, and why the “at least Dec 31 2022” timeline? Ben, Horizons has this unique tax structure with some of their ETFs, like HXT, where you don't receive the dividend payouts as income, but instead they get added to the fund so that you instead receive more capital gains. I realize that I'm maybe oversimplifying things a bit here, but essentially by holding an ETF like HXT in a personal taxable or corporate trading account, some Canadians save money by reducing their clawbacks when it comes to things like CPP, OAS, the Canada Child Benefit (CCB), and avoid the high tax rate when investing in a corporate account.Now in the past, the government closed this, (what I would consider a) loophole, but Horizons figured out a way to restructure their ETFs so that Canadians can still get these tax savings.This raises the concern of: What if the government changed things again, closes the 2nd loophole, and Canadians that were holding Horizons ETFs like HXT start selling off ETFs like HXT in large quantities because it no longer has this tax advantage? In this scenario, would the ETF plummet in price? Or no, because the ETF is still holding companies (in a way), and it's not like the value of all those companies will drop because there is a massive sell-off of the Horizons ETFs. The last time this closing of the “loophole” happened where the government changed the rules, I recall Horizons doing a press release where they said that if they can't find a workaround, they may have to close down those ETFs. If that was to happen in the future, would Canadian investors be hurt by this? Bryan and Ben: The other concern with HXT, is that it is only 60 Canadian companies, and I think most Canadians (myself included) would rather go for the total market approach with an ETF like ZCN, where they are now getting the entire S&P/TSX index with its 240 stock holdings.Do you think this tradeoff is worth it? (where you're getting less diversification, but some potential tax savings and/or clawback reduction on government benefits). Bryan and Ben, most Canadians do have a home country bias when it comes to their investment portfolio. Even when we look at asset allocation ETFs from all the major providers, they definitely hold more of Canada than Canada's percentage of the world equity markets. Why is that, and what is your stance on what percentage Canadian stocks should make up of a Canadian DIY investor's investment portfolio? US Market ETFs: Alright, let's jump to the US market. XUU still appears to be the favourite here among the panelists, as far as Canadian listed, US total market index ETFs go. The runner-up seems to be VUN which is comparable in terms of US stock market representation, but has a higher fee of 0.15% vs XUU's extremely low fee of 0.07%.Do you guys have any thoughts and comments on this one? International ETFs: Alright, let's jump to international stocks. Can you give us your thoughts on these, while touching on some of the nuances when it comes to choosing the different combinations, from the different providers, when it comes to emerging and developed international markets?

Using cortical neuron markers to target cells in the dorsal cochlear nucleus

Link to bioRxiv paper: http://biorxiv.org/cgi/content/short/2020.09.19.304550v1?rss=1 Authors: Malfatti, T., Ciralli, B., Hilscher, M. M., Edwards, S. J., Kullander, K., Leao, R. N., Leao, K. E. Abstract: The dorsal cochlear nucleus (DCN) is the first auditory region that integrates somatosensory and auditory inputs. The region is of particular interest for auditory research due to the large incidence of somatic tinnitus and increased aberrant activity in other forms of tinnitus. Yet, the lack of useful genetic markers for in vivo manipulations hinders the elucidation of the DCN contribution to tinnitus pathophysiology. In this work, we assessed whether adeno-associated viral vectors (AAV) containing the calcium/calmodulin-dependent protein kinase 2 alpha (CaMKII) promoter and our mouse line of nicotinic acetylcholine receptor alpha 2 subunit (Chrna2)-Cre can be used to target specific DCN populations. The CaMKII promoter is usually applied in studies of principal neurons of neo and paleocortex while Chrna2-cre mice express Cre recombinase in cortical dendrite inhibiting interneurons. We found that CaMKII cannot be used to specifically target excitatory fusiform DCN neurons. EYFP expression driven by the CaMKII promoter was stronger in the fusiform layer but labelled cells showed a diverse morphology indicating that they belong to different classes of DCN neurons. Light stimulation after driving Channelrhodopsin2 (ChR2) by the CaMKII promoter generated spikes in some units but firing rate decreased when light stimulation coincide with sound presentation. Expression and activation of eArch3.0 (CaMKII driven) in the DCN produced spike inhibition in some units but, most importantly, sound-driven spikes were delayed by concomitant light stimulation. We explored the existence of Cre+ cells in the DCN of Chrna2-Cre mice by hydrogel embedding technique (CLARITY). There were almost no Cre+ cell bodies in the DCN; however, we observed profuse projections arising from the ventral cochlear nucleus (VCN). Anterograde labeling Cre dependent AAV injected in the VCN revealed two main projections: one arising in the ipsilateral superior olive and the contralateral medial nucleus of the trapezoid body (bushy cells) and a second bundle terminating in the DCN, suggesting the latter to be excitatory Chrna2+ T-stellate cells). Stimulating ChR2 expressing terminals (light applied on the DCN) of VCN Chrna2+ cells increased firing of sound responding and nonresponding DCN units. This work shows that molecular tools intensively used in cortical studies may be useful for manipulating the DCN especially in tinnitus studies. Copy rights belong to original authors.

This episode: A cancer-killing virus could help increase success of treatment of a form of eye cancer in children! Download Episode (8.0 MB, 8.7 minutes) Show notes: Microbe of the episode: Acanthamoeba polyphaga mimivirus News item Takeaways Cancer obviously is a serious concern, and can be tricky to treat because there are endless varieties in all different places in the body, each of which can have its own expected progression, aggressiveness, and methods of treatment to take into account. Even more serious is when the cancer is in very young children, as is often the case with a cancer of the eye called retinoblastoma. There are about 8000 cases of this disease per year, and when treatment is unsuccessful, it can lead to the loss of one or both eyes. In this study, investigators looked into using a cancer-targeting, oncolytic virus to complement the normal treatment of chemotherapy. The virus for the most part remained localized to the eye where it should be, and targeted the cancer instead of healthy cells, and so seems promising. In the small trial with two patients included in this study, the virus didn't cause a complete recovery, but showed some modest promising results.

Army CWO4(ret) Shane Campos and his wife Jenny discuss with host Jim Fausone "Why Veterans Care Network?" They believe that veterans should have access, regardless of their DD214 discharge status, to high quality, affordable and accessible primary health care. It is VCN mission to become a conduit between the veteran and their positive health outcomes and not a barrier to any veteran looking for or in need of service. VCN plans to achieve this by partnering with a service provider to operate private health centers locally in the Metro Detroit area in places where communities value supporting our veterans. Our VCN veterans will have access to primary health services for acute needs (cough, sore throat), wellness services (physicals, well women care, etc.), lab draws, medications, wellness coaches, telemedicine, etc. all for a low monthly membership fee. VCN will have low wait times, patients get quality time with their provider, and they leave our center with their generic medication in hand; no trips to the pharmacy! The best part, veterans’ families are OUR families too, and they will also have access to these medical services.
