Serverless Architectures on AWS - Week 2 Quiz

Week 2: Serverless Event Driven Architectures

You start this week with an introduction to event-driven architectures (EDAs). You learn about AWS services that you can use for messaging, such as Amazon Simple Queue Service (Amazon SQS), Amazon Simple Notification Service (Amazon SNS), and Amazon EventBridge. Finally, you explore how to use AWS Step Functions to help you build applications that implement a workflow.
