Step Functions
AWS Step Functions is a serverless orchestration service that lets you coordinate multiple AWS services into serverless workflows. It uses state machines and tasks to define and execute sequences of steps, handling errors, retries, and parallel execution automatically. This enables developers to build resilient, scalable applications by managing complex business logic and microservices interactions.
Developers should use Step Functions when building applications that require coordinating distributed components, such as microservices, AWS Lambda functions, or ECS tasks, especially for workflows involving error handling, retries, or parallel processing. It's ideal for use cases like data processing pipelines, order fulfillment systems, or automated IT operations, as it simplifies state management and reduces boilerplate code for orchestration.
