Downgrade RDS Instance size

Question

In doing some performance testing in a non-prod environment, I'd like to temporarily increase the instance size to get a baseline number. If I do this, how difficult is it to reduce the instance size in order to keep costs low?

Answer

It is very easy. You can just call modify-db-instance to scale up and then after your test just call modify-db-instance to scale down.

You can also create a blue green deployment that will clone your environment. Then you can scale the green instance, run your tests, and then delete green and the blue green deployment.

Answer

It is the same process as choosing a larger instance type.
