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

* If you added a Lambda layer for FFMpeg as suggested in the experiments at the end of [Chapter 10](https://www.educative.io/courses/running-serverless-applications-aws-lambda/interesting-experiments-xonVvv7YzY9), then modify the request processor to allow the uploading of videos, and introduce another port and adapter for video thumbnails. 

* Configure throttling to allow only one or two concurrent executions, and then try uploading many images in quick succession. Check CloudWatch logs and metrics to spot the throttling in action.

* Change the client workflow code to check for throttled requests, and handle them by pausing and retrying automatically.

* Add a few more test cases to improve test coverage. For example, add a test case for generating the upload policy.
