Operations on PROD

Code

Finally, the PROD environment is the place where the code needs to be and where the end users are able to see the changes we did in one complete development cycle.

The release consists only in a switch command that brings the code to the latest tag that was created above. This way we minimize the downtime and if something goes wrong, we can quickly revert to the previous stable tag.

Database

Exactly like with the STG environment, only the change scripts with the version number higher than DB version are being executed. A change script can be applied only once.

Steps:
1. the change scripts with the version number higher than DB version are being executed
2. then the data change scripts with the version number higher than DB version are being executed
