Bank in 2019, Microsoft and Oracle announced a partnership enabling customers to migrate and run mission-critical enterprise workloads across Microsoft Azure and Oracle Cloud. This extremely low-latency, private connection can distribute workload, and it opens a world of possibilities including deploying applications using the best of Oracle Cloud and Microsoft Azure. Scenarios such as running Oracle E-Business Suite in Azure with its databases operating in Oracle Cloud are now entirely possible. Highlights on the current offerings, support and licensing models, details on performance, and a list of pitfalls are covered in this presentation. Join this presentation to learn more about what the Oracle and Microsoft partnership is all about, how it works, and what this means for cloud interoperability.

The Microsoft Azure and Oracle Cloud Interconnect
What It Is
▪ A cloud interoperability partnership
▪ Enables customers to migrate and run mission-critical enterprise workloads across
Microsoft Azure and Oracle Cloud
▪ Receive a highly optimized, best-of-both-clouds experience
Marketing Speak
▪ “Makes lift-and-improve migrations seamless”
▪ “Delivers direct, fast and highly reliable network connectivity between two clouds”
▪ “Provide first-class customer service and support that enterprises have come to expect
from the two companies”
New and Innovative Scenarios
▪ Seamlessly connect Azure services, like Analytics and AI, to Oracle Cloud services, like
Autonomous Database
▪ Run Oracle E-Business Suite or Oracle JD Edwards on Azure against an Oracle Autonomous
Database running on Exadata infrastructure in the Oracle Cloud

The Microsoft Azure and Oracle Cloud Interconnect
Current Offerings
▪ Direct interconnect is available in Ashburn (North America)
and Azure US East, with plans to expand additional regions in
the future
▪ Unified identity and access management, via a unified single
sign-on experience and automated user provisioning, to
manage resources across Azure and Oracle Cloud
▪ Oracle applications (JD Edwards EnterpriseOne, E-Business
Suite, PeopleSoft, Oracle Retail, Hyperion) certified to run on
Azure with Oracle databases (RAC, Exadata, Autonomous
Database) deployed in Oracle Cloud
▪ Oracle applications can use Azure Active Directory as the
identity provider and for conditional access
▪ A collaborative support model
▪ Oracle Database will continue to be certified to run in Azure
on various OS’, including Windows Server and Oracle Linux

The Cross-Cloud Interconnect
• Oracle and Microsoft have already done all
the tedious, time-consuming work for you by
providing low-latency, high-throughput
connectivity between their two clouds
Traffic Flow Between Clouds
▪ High-throughput, low-latency, private
network connection
▪ Data centers in the Ashburn, Virginia
region
▪ Access the connection by using either
Oracle FastConnect or Microsoft
ExpressRoute
▪ No intermediate service provider required
to enable the connection
▪ Secure private connection between the
two clouds
▪ No exposure to the internet
▪ High availability and reliability
▪ Built-in redundant 10-Gbps physical
connections between the clouds
▪ Straightforward, one-time setup

Security
• Only workloads are allowed between both clouds through the interconnection
• No access from one cloud through the other
Security Isolation
▪ Traffic from networks other than Oracle
Cloud and Azure can’t reach one cloud
through the other cloud
▪ Example:
▫ Customers can’t reach Oracle Cloud
Infrastructure through Azure
▫ No traffic between your on-
premises network through the
Azure virtual network (VNet) to the
Oracle Cloud Infrastructure virtual
cloud network (VCN), or vice versa
▫ If you need to reach Oracle Cloud
Infrastructure, you need to deploy
FastConnect directly from your on-
premises network

Connecting the Cloud Networks
1. Setup an Azure VNet with subnets and a virtual network gateway
▪ Create an ExpressRoute circuit and select Oracle Cloud Infrastructure
2. Setup an Oracle Cloud Infrastructure VCN with subnets and an attached DRG
▪ Create a FastConnect connection and select Microsoft Azure and enter the service key that
you got from Azure
3. Ensure no overlapping IP addresses between your VCN and VNet
The private virtual circuit is provisioned automatically between the two clouds.
✓
Note: On-Prem Connectivity
You need a separate ExpressRoute
or FastConnect circuit to connect
your on-premises network to
Oracle Cloud Infrastructure or
Microsoft Azure through a private
connection

Oracle Software Licensing Policy in Microsoft Azure
• Oracle provides license mobility for customers who want to run Oracle software on
Microsoft Azure (see Licensing Oracle Software in the Cloud Computing Environment)
– With Standard Edition in the product name, the pricing is based on the size of the
instance
– 2 vCPUs = 1 Oracle Processor license (if hyper-threading is enabled)
– 1 vCPU = 1 Oracle Processor license (if hyper-threading is not enabled)
– Every 4 Azure vCPUs used (rounded up to the nearest multiple of 4) equates to a
licensing requirement of 1 socket
– Oracle Standard Edition may only be licensed on Authorized Cloud Environment
instances up to 8 Azure vCPUs
• The same applies for AWS

The Accenture Whitepaper
• Titled The Oracle and Microsoft Cloud Partnership: Testing the Connection
• Leveraging the interconnect eliminates the “limitations of the public internet”
• No need to “contract directly with a Telco provider to set up a dedicated
connection” which can take “as long as 12 weeks” and be “very costly and
complex” (and can cost “as much as $100,000 per year in recurring charges”)
• Customers must consider ease, performance, and value
• Engineers ran a continual test for more than 2 weeks, collecting more than
32,000 data points
Results
Consistent latency of 1.5ms round trip time (RTT) between the 2 clouds

Final Thoughts
• Applications can span clouds, such as the web
and applications tiers in one cloud and the
database layer in another
• Customers can leverage new migration and deployment scenarios
• Market is showing more interest in moving workloads to Microsoft Azure
versus Oracle Cloud Infrastructure
• The Oracle Database remains the flagship enterprise database of choice,
though open source alternatives are considered purely from a cost
perspective
