> while largely maximising operational costs

The core services are cheap. S3 is cheap. Dynamo is cheap. Lambda is exceedingly cheap. Not understanding these services on their own terms and failing to read the documentation can lead one to use them in highly inefficient ways.

The "cloud" isn't just "another type of server." It's another type of /service/. Every costly stack I've seen fails to accept this truth.
