I agree with previous comments about this being pretty vague. Here are some general ideas though:
Automate backups if applicable
Automate fail-over if applicable
Use Infrastructure / Configuration as Code
Use Schema Migrations
Implement CI/CD pipelines with static analysis (such as linting / anti-pattern checking) and automated testing.
Beyond these basics, I think people would really need to know what problem you are trying to solve. There's no point in automating a solution if the problem isn't defined and understood. Further, many solutions are really going to depend on your environment.
