Orchestration Lightning: Rapid-Fire AWS Step Functions Patterns
summary
Shows concrete Step Functions patterns with exact tools and results: a CRUD machine implemented with API Gateway VTL and DynamoDB to avoid Lambdas for sync APIs; a chatbot that runs parallel RAG history + knowledge and calls Bedrock’s converse API (multi‑model parallelism: Claude/Nova/Llama) for A/B testing; a dynamic mapper that spawns up to 10,000 concurrent subworkflows to process buckets (turns a 3‑month/$60k job into ~30s/$400); and JSON/variables that collapse many states into single expressions.
