AWS MWAA: The Practitioner's Unvarnished Guide

I remember the first time I sat down properly with the Step Functions architecture our team inherited. Someone had designed it thoughtfully — real engineering thought had gone into it when it was built. But what I was looking at in the console was a map of state machines and Lambda functions that had grown well past the point where anyone could hold it in their head. The first production issue we had to debug on that setup took most of a working day. Not because the problem was complicated — it wasn’t — but because finding it meant jumping between CloudWatch log groups, correlating timestamps, building a mental picture of which Lambda had received what input and where the chain had broken. Every time I thought I had it, another log group. Another timestamp comparison. Another dead end.
