In the world of modern development, serverless computing has become table stakes. Serverless computing has seen a major uptake with AWS Lambda having an increased adoption of 667% in 2018. Companies are making the switch to serverless for shorter time to market and decreased operational costs, but for you the advantage lies in the ability to offload the burden of managing infrastructure to serverless platforms, so you can focus on building even better apps.

In this course, you will learn how to run serverless applications using AWS Lambda. You’ll start with the basics such as creating a web service where you’ll learn the steps to deploy an AWS Serverless Application Model (SAM). You’ll then move on to more advanced topics such as handling HTTP Requests, using external storage, and managing sessions and user workflows. By the end of this course, you will be ready to work with AWS Lambda in a professional setting, and you’ll have a great, transferable skill that employers will love to see.

Running Serverless Applications with AWS Lambda

* Try deploying the stack again using the same name.
* Try creating a new stack, using a different name, from the same output template (you don't need to build and package again, just deploy under a new name).

* Try changing the response message in the Lambda function source and update only one of the deployed stacks, then compare the results.

* Try updating a stack with a broken CloudFormation output template, for example by modifying the `CodeUri` for the function to point to an invalid URL directly in `output.yaml` before deploying. Observe the deployment in the AWS Web Console and see how CloudFormation restores it to the last known working state. 

* Run `aws cloudformation help` to see the full list of available CloudFormation tools, then experiment with some of them. For example, try deleting one of the deployed stacks.
