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

* Make the client web page attractive by styling it using CSS. 

* Configure a CloudFront CDN to compress and locally cache static assets, then reconfigure the application so users access it through the CDN.

* The error handling in this chapter only acts on problems during file uploads, not on problems during file conversion. Using the dead-letter queue technique from [Chapter 9](https://www.educative.io/courses/running-serverless-applications-aws-lambda/handling-asynchronous-errors-with-dead-letters), detect conversion errors and save a marker error file somewhere on S3 where the client can detect it. Then change the client-side workflow to poll for that file while waiting on results and notify clients about conversion errors.

In the next lesson, you have a short quiz, so buckle up!
