Why Azure is a Great Cloud Destination for Oracle Applications

This summer Oracle and Microsoft announced a partnership that bridged the gap between Microsoft Azure and Oracle Cloud Infrastructure (OCI). Microsoft and Oracle will now be working together to help businesses embrace cloud computing by providing increased choice and flexibility in their deployment of Oracle software.

Customers can now seamlessly connect Oracle Cloud services, like the autonomous database and real application clusters to Azure services for example, data analytics and AI. Now enterprises can run part of a workload within Azure and another part of the same workload within the Oracle Cloud, the partnership delivers a highly optimized, best-of-both-clouds solution.

Oracle is now a service provider for ExpressRoute enabling direct connectivity to Azure. This means customers no longer need to route the traffic through an intermediate service provider for establishing connectivity between Azure and OCI.

And here we look at some of the options for running Oracle solutions using Azure Cloud infrastructure.

Running Oracle databases on Azure Public Cloud
You can run Oracle databases on Azure infrastructure using Linux images available in the Azure Marketplace:

  • Oracle Database 12.1, 12.2, and 18.3 Enterprise Edition
  • Oracle Database 12.1, 12.2, and 18.3 Standard Edition

You can also create a virtual machine based on a custom image you create from scratch in Azure or you can upload a custom image from your on-premises environment.

These virtual machines can be configured with multiple attached disks to improve database performance by installing Oracle Automated Storage Management (ASM).

By migrating to cloud companies can innovate faster, increase productivity, lower costs, and benefit from enhanced security features.

Running Oracle Applications on WebLogic Server and Oracle Linux
Customers can run enterprise applications in Azure on supported Oracle operating systems. The following are some of the images are available in the Azure Marketplace:

  • Oracle WebLogic Server 12.1.2
  • Oracle Linux (UEK) 6.8, 6.9, 6.10, 7.3, 7.4, 7.5, and 7.6

Deploy Oracle applications on Azure
Customers can use Terraform templates to set up Azure infrastructure and install Oracle applications validated and supported to run in a cross-cloud configuration:

  • E-Business Suite
  • JD Edwards EnterpriseOne
  • PeopleSoft
  • Oracle Retail applications
  • Oracle Hyperion Financial Management

They can also deploy custom applications in Azure that connect with OCI and other Azure services.

Performance and scalability benefits
Customers can achieve the scalability, flexibility and compliance their business requires for Oracle Enterprise workloads.

  • Upgrade infrastructure performance with hyper-threaded Azure Virtual Machines featuring up to 128 vCPUs and 6 TB of memory.
  • Azure Disk Storage offers persistent, highly secure and cost-effective SSD options to support your mission-critical Oracle applications.
  • Ensure that Oracle applications always have the storage and compute resources they need with infrastructure flexibility from Azure.

Disaster recovery and high availability options
Help your business to keep doing business—even during major IT outages with the following features:

  • DBA’s can configure Oracle Data Guard, Active Data Guard, or Oracle GoldenGate on Azure infrastructure in conjunction with availability zones.
  • Customers can utilise Azure Site Recovery to orchestrate and manage disaster recovery for their Oracle Linux VMs in Azure and their on-premises or physical servers.
  • Use Oracle Database Cloud Services (Autonomous Database, RAC, Exadata, DBaaS, Single Node) in conjunction with Oracle applications running in Azure.
  • Enable Oracle Real Application Clusters (RAC) in Azure using FlashGrid SkyCluster.

The resulting business benefits include:

  • Protection from downtime
  • Avoiding lost revenue
  • Simplification of maintenance
  • Maximum system availability and flexibility
  • Improved agility and resilience

Licensing considerations /Cost reduction
Deployment of Oracle applications in Azure is based on a “bring your own license” model. It’s assumed that you are properly licensed to use Oracle software and that you have a current support agreement in place with Oracle. Oracle has guaranteed license mobility from on-premises to Azure.

  • Lower Oracle licensing costs with Azure constrained-core virtual machines optimised specifically for Oracle workloads.
  • Reduce costs, up to 72 per cent compared to pay-as-you-go prices, by reserving resources in advance for your predictable workloads with Azure Reserved VM Instances (RIs).
  • Re-use on-premises licences to run Windows Server VMs on Azure with Azure Hybrid Benefit and combine reserved instances with Azure Hybrid Benefit to save up to 80 per cent.
  • Get three more years of free extended security updates for Windows Server 2008 and 2008 R2 when you migrate to Azure.

With simplified licensing models, customers can deploy enterprise Oracle applications on Azure with the same processor mapping as their existing on-premises deployments. This results in an easier migration to cloud.

Unified identity and access management
With Azure Active Directory, Microsoft extended the features of AD to the cloud enabling single sign-on for enterprise applications and web applications deployed in the cloud.

With the cross-cloud connectivity, Oracle customers can integrate access management based on Azure Active Directory through a federated identity model. This delivers a unified mechanism for authentication and authorizing users and applications.

The benefits of federated Identity include single sign-on, reduced security risks and increased organisational productivity.

Strengthen security posture with Azure
Enterprises can rely on a cloud that is built with customised hardware, has security controls integrated into the hardware and firmware components, plus added protections against threats such as DDoS.

  • Take advantage of the multi-layered state-of-art security delivered in Azure data centres globally
  • Protect workloads quickly with built-in controls and services in Azure including identity, data, networking and apps.
  • Detect threats early with unique intelligence
Sample reference Oracle architecture on Azure

Oracle and Microsoft have now provided customers the flexibility to build and deploy applications in Oracle Cloud Infrastructure and Azure by providing a robust, reliable, low-latency, and high-performance path between the two clouds. With this partnership, their customers can migrate their entire set of existing applications to the cloud without having to re-architect anything, preserving the large investments they have made while also opening the door for new innovation.

Rackspace delivers unmatched Microsoft Azure expertise and tech-enabled services to support enterprise digital transformations. As a Gold partner, we closely collaborate with Oracle on everything from application monitoring to fully vetted architecture.
