Recently I've been doing some research on the abilities to restore MySQL databases on AWS RDS. The customer requirement was to have 15 minutes RPO for databases. Can we meet the requirement with AWS RDS alone?

At the first moment I thought so, but then I considered what happens when someone does "accidental deletion" of RDS instance. Yeah, I know...

Recently I've tried to write a lambda function in Go, which connects to MySQL database on RDS instance and use IAM Authentication instead of "traditional" approach with passwords (which I think is an anti-pattern in cloud environments). I've spent way too much time to solve the problem, but the documentation and examples on the Internet are lacking and wrong in some places... It's time to document...
