Compute + DB should cover a lot of use cases, but it’ll be great to have support for more AWS services. DNS (Route53) issues are a pain to deal with for example.
A route 53 propagation issue caused a bunch of our web servers to be unable to connect to the read replicas of our RDS cluster. The cluster scaled in a RR, but the DNS change took hours to propagate. The web servers kept trying to connect to the replica that didn't exist.
Our workaround was to put the IP address in the hosts files - not an ideal setup, but it got the job done.
