Answer: AWS Step Functions

## Explanation **AWS Step Functions** is the correct answer because it is specifically designed as a low-code, visual workflow service that allows developers to build distributed applications by orchestrating AWS services into serverless workflows. ### Key Features of AWS Step Functions: - **Visual Workflow Designer**: Provides a graphical interface to build and visualize workflow logic - **Low-Code Approach**: Reduces the amount of code needed to coordinate multiple AWS services - **State Management**: Handles error handling, retries, and parallel processing automatically - **Distributed Application Coordination**: Coordinates components across multiple AWS services like Lambda, ECS, SNS, etc. ### Why Other Options Are Incorrect: - **AWS Config**: A service for assessing, auditing, and evaluating AWS resource configurations - not for workflow orchestration - **AWS Lambda**: A serverless compute service for running code without provisioning servers - while it can be part of workflows, it doesn't provide visual workflow design - **Amazon CloudWatch**: A monitoring and observability service for AWS resources and applications - focused on metrics, logs, and alarms, not workflow orchestration AWS Step Functions enables developers to build resilient workflows with built-in error handling, making it ideal for distributed applications that require coordination between multiple services.
