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

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.

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. Until then, this is Lois Houston…

Nikita: And Nikita Abraham, signing off!
