Put a PaaS application behind Cloudfront CDN
It is possible to put an application behind a Cloudfront CDN when it is on the PaaS with a custom domain. This means you can quickly set up a new application and have it serve traffic at scale.
There are instructions on how to set this up in their docs.

Once it’s merged you must then deploy the changes
