AWS Step Functions
AWS Step Functions is a serverless orchestration service that allows developers to coordinate multiple AWS services into serverless workflows. It uses state machines and tasks to define sequences of steps, handling error handling, retries, and parallel execution automatically. This enables building resilient and scalable applications by managing complex business logic across distributed components.
Developers should use AWS Step Functions when building applications that require coordinating multiple microservices, handling long-running processes, or managing complex workflows with error handling and retries. It is particularly useful for serverless architectures, data processing pipelines, and business process automation, as it reduces boilerplate code and improves reliability by managing state transitions and failures.
