Orchestrating with AWS Step Functions
Design and implement complex, stateful workflows using AWS Step Functions to coordinate multiple Lambda functions and other AWS services.
The Need for Workflow Orchestration
Imagine building a complex application like an e-commerce order fulfillment system. It involves many steps:
- Processing payment
- Updating inventory
- Notifying shipping
- Sending confirmation emails
Each step might be handled by a different service, like a Lambda function. How do you ensure they run in the correct order, handle failures, and pass data between them?
What is AWS Step Functions?
AWS Step Functions is a serverless workflow service that lets you coordinate multiple AWS services into business-critical applications.
It visually represents your application's components as a series of steps, making it easy to build and run multi-step applications.
Think of it as a conductor for your serverless orchestra!
