A current architecture uses many Lambda functions invoking one another as a large state machine.The coordination of this state machine is legacy custom code that breaks easily.
Which AWS Service can help refactor and manage the state machine?
AWS Data Pipeline
AWS SNS with AWS SOS
Amazon Elastic MapReduce
AWS Step Functions
Explanations:
AWS Data Pipeline is designed for orchestrating data workflows, not for managing state machines or coordinating Lambda functions.
AWS SNS (Simple Notification Service) and AWS SQS (Simple Queue Service) are messaging services, not designed for orchestrating state machines.
Amazon Elastic MapReduce (EMR) is a big data processing service, not suited for state machine coordination or managing Lambda function invocations.
AWS Step Functions is specifically designed to coordinate workflows by managing state machines and orchestrating Lambda functions, making it the right choice for this use case.
I value that the answer is:
AWS Step Functions
