Analysis A brief look at Oracle Database Service for Azure (ODSA) Max Jahn, September 20, 2022November 13, 2024 In the past, I have written several posts about the interconnect between Oracle Cloud (OCI) and Microsoft Azure. Usually, this interconnect is used to host databases in OCI. However, Azure is used to run applications and other components. While it could be a good solution for some businesses, it had several drawbacks for companies who wanted to run Oracle databases in the cloud without having to manage multi-cloud environments. In a new PaaS-style approach to running databases in OCI and hiding much of the interconnect complexity from Azure users, Oracle has released Oracle Database Service for Azure (ODSA). In my post, I will take a brief look at this solution. Continue Reading
