If you can get the data out of the downed AZ, don't have state you need to transfer and are not shot in the foot once the primary replica comes online again. I've rarely deployed an app where it was as easy as just to change a region variable.

Yeah the data stores are the ones that I would always keep multi AZ no matter what. Everything else is stateless and can be moved quickly.

Write an article on that because you make it sound simple. Or better yet, start a company that configures this for companies.

Nothing is inherently simple.

Depending on the size of the company it can be simple or hard. Most companies that need this are not huge. Things like RDS, Elasticache, ECR and Secrets have multi AZ integrated so not hard to do it. If you operate on ECS or EKS it's pretty straightforward to boot up nodes and load balancers in another AZ.

Maybe you have a system that requires more hands on work and want to explain your point of view? I don't appreciate the snarky responses tho.
