A developer is building an application that requires a complex sequence of AWS Lambda functions to execute in a specific order. Some functions must run in parallel, and there must be error handling and retry logic if a function fails. Which AWS service is BEST suited for orchestrating this workflow?

Answer options:

Amazon SQS

AWS Step Functions

Amazon EventBridge

AWS Systems Manager

How to approach this question

Match 'complex sequence', 'orchestrating', and 'state management' with AWS Step Functions.

Full Answer

B.AWS Step Functions✓ Correct

AWS Step Functions is a visual workflow service that helps developers use AWS services to build distributed applications, automate processes, orchestrate microservices, and create data and machine learning (ML) pipelines. It handles state, parallel execution, and retries natively.

Common mistakes

Choosing SQS. While SQS connects microservices, it does not orchestrate them or manage workflow state.
