AWS Step Functions

ELI5 — The Vibe Check

Step Functions is like a flowchart that actually runs. You draw boxes for each step — 'charge the card,' 'send the email,' 'update the database' — and AWS runs them in order, handles retries, and even waits days if needed. It's project management for your code, except it never misses a standup.

Real Talk

AWS Step Functions is a serverless orchestration service that lets you coordinate multiple AWS services into workflows using state machines defined in Amazon States Language (ASL). It supports sequential, parallel, branching, and error-handling patterns with built-in retry logic and visual monitoring.
