Lets Build AWS Step Functions with Lambda, DynamoDB, SNS and more

AWS Step Functions
Assemble functions into business-critical applications
AWS Step Functions is a serverless function orchestrator that makes it easy to sequence AWS Lambda functions and multiple AWS services into business-critical applications. Through its visual interface, you can create and run a series of checkpointed and event-driven workflows that maintain the application state.
1. Define your visual workflow in Workflow Studio and the console will auto-generate the code for you. You can also code it yourself using code snippets in the console or locally with VS Code.
2. Specify the resources, such as Lambda functions and SNS topics, that you want to trigger in your workflow.
3. Start an execution to visualize and verify that the steps of your workflow are operating as intended. Inspect and debug your execution history from the console directly.

Web service integration
Build workflows that coordinate tasks across different services. Yelp transformed a monolithic business-critical code base into a simpler and more resilient billing service.
Data processing
The Guardian newspaper automated serverless data processing and subscriber management using AWS Step Functions, AWS Lambda, and Amazon CloudWatch Events.
