This is a call to the RDS API to create new instances of MySQL.

Amazon's Go API has a few quriks (like the pointers for everything needing the aws.String and aws.Bool convenience functions), but once you get into it flows easily.

Since the AWS functions are all in interfaces, I can mock github.com/aws/aws-sdk-go/service/rds/rdsiface using https://github.com/maxbrunsfeld/counterfeiter and write expectations in my unit tests.
