What it is

AWS Step Functions is a cloud workflow service for coordinating AWS services and HTTPS endpoints, including SaaS applications. Workflows are state machines written in Amazon States Language, with Workflow Studio providing a visual designer. Definitions can branch, run steps in parallel, set timeouts, retry failures, and handle errors with try/catch or rollback patterns. Service integrations connect to over 200 AWS services, while AWS SDK integrations can invoke over 9,000 API actions. HTTPS endpoint integration connects directly to HTTP-based services. Distributed Map can process large datasets, including Amazon S3 data, with up to 10,000 parallel child executions in one Map Run. Execution history, CloudWatch Logs, and AWS X-Ray support review and tracing. Standard executions can run for up to one year; Express executions can run for up to five minutes. Task, state, or execution input and output is limited to 256 KiB. A Free Tier plan is listed at free indefinitely; Standard and Express plans bill usage.
