Interesting Experiments

You will have a firm grasp on the concepts covered in this chapter after performing the interesting experiments in this lesson!

  • 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, 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!
