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.

Of course there are tools to do that in a more sensible way, one of them being the OS Management tooling that is available for free in Oracle Cloud. This post shows how to do so using OCI CLI.

Keeping Oracle Serverless Functions warm with a poor man’s Cron
Oracle Functions suffer from one of the minor issues of having a container based platform that will spin down the container after some time of running idle. The next time the function is called, the container will be spun up again, taking some seconds time to do so. This is…
