aws step functions

Step functions provide a visual interface for serverless applications, enabling developers to build and run serverless applications as a series of steps.

These are orchestrators for serverless applications. A step function allows us to manage logic of the application, including:

• Sequencing
• Error handling
• Retry logic
• Logging of each execution step

Building step functions

Step functions can be built using JSON objects or using the new AWS visual builder. The visual builder allows users to create "workflows" that give flexibility in passing data through interfaces, calling services, etc.
