Orchestrating Workflow for Microservices Integration
summary
Shows how to implement reliable orchestration for microservices using AWS Step Functions with concrete artifacts: a JSON state machine in Amazon States Language, three live scenarios (auto-approve, human-review-then-approve, human-review-then-reject), and a demo of pause/resume via an external service callback. Explains turning serial checks into parallel identity and address checks, encoding conditional human review transitions, and using Step Functions to implement a saga with explicit compensating actions (cancel payment, cancel logistics) and built-in retries and execution history for debugging.
