Microsoft Azure is a top choice for enterprises, particularly those deeply integrated with the Microsoft technology stack. Recognizing the needs of their shared customers, Oracle and Microsoft have formed a strategic partnership to create the Oracle Interconnect for Azure. This dedicated, low-latency, private connection between the two clouds allows businesses to run applications on Azure while connecting to Oracle databases running on OCI as if they were in the same data center.
This hybrid approach offers the best of both worlds: customers can use their preferred Azure services for applications while relying on the power of OCI for their backend databases. This solution is ideal for companies looking to modernize their applications using Azure's services without undertaking a complex and risky database migration. For more information on cloud applications what exactly does that mean, exploring hybrid models is a great start.
Multi-Cloud and Beyond: A Strategic Imperative
The conversation is shifting from 'which single cloud' to 'what is the right mix of clouds'. A multi-cloud strategy, leveraging services from OCI, AWS, and Azure, is becoming the standard for enterprises seeking resilience, flexibility, and access to best-in-class technology. Oracle's recent moves to enable its database services directly within Azure and AWS data centers, with products like Oracle Database@Azure and Oracle Database@AWS, confirm this trend. This approach allows you to place workloads where they perform best and make the most financial sense.
For businesses developing cloud-native applications, this flexibility is paramount. It allows developers to use the tools they prefer while connecting securely to robust Oracle data backends, no matter where they reside.
