What is the main purpose of AWS Step Functions?

The main purpose of AWS Step Functions is to serve as a visual workflow service that allows users to automate IT processes. By using Step Functions, developers can build complex workflows by combining different AWS services, enabling orchestration of multiple tasks into a cohesive flow. This service provides a graphical interface that makes it easier to design and monitor workflows, allowing users to focus on the business logic rather than intricate code structures.

Step Functions enhance productivity by handling state management, error handling, and retry logic, which are common concerns when automating workflows. This level of orchestration supports modular and scalable application designs, fostering the development of serverless applications with AWS Lambda or other services.

The other options do not align with the primary function of AWS Step Functions. Monitoring services, vulnerability scanning, and continuous compliance assessments are provided by different AWS services designed specifically for those needs, making them distinct from the workflow automation capabilities that Step Functions offer.
