DevOps isn’t running SQL Server in a container and pushing code to it from Jenkins
When we talk about DevOps we envision that we have the ability to check-in code, spin up a new environment, deploy, test and push that code to production and be in the pub at 4.
We know that by having the right tooling in place we can make releases more reliable and more frequent enabling us to deploy the changes that the business want when they want them rather than every x days/weeks/months/years/decades.
