Developing Serverless Applications with AWS Step Functions

Why it matters

Step Functions is the deterministic alternative 2.1.5 and 2.1.6 weigh against autonomous agent planning, and it is also the mechanism 2.1.9 depends on for approval callbacks.

What to practise

Build and run a state machine with task states, retries, and error handling in a serverless application. Watch how state, retries, and failure transitions are expressed as explicit workflow configuration rather than agent reasoning.

How it fits

Use the result to judge 2.1.5’s control-versus-autonomy trade-off directly, and notice the retry and error-handling shapes that 2.1.6 bounds around model calls and that 2.1.9 reuses for waitForTaskToken approval steps.
