Automating AWS Lambda Function Error Handling with AWS Step Functions

AWS Step Functions makes it easy to coordinate the components of distributed applications and microservices using visual workflows. You can scale and modify your applications quickly by building applications from individual components, each of which performs a discrete function.

You can use Step Functions to create state machines, which orchestrate multiple AWS Lambda functions to build multi-step serverless applications. In certain cases, a Lambda function returns an error. Regardless of whether the error is a function exception created by the developer (e.g., file not found), or unpredicted (e.g., out of memory), Step Functions allows you to respond with conditional logic based on the type of error message in the form of function error handling.
