Nothing particularly novel but the setup of configuring CloudFront to connect to S3 and handle SSL termination, a DNS record pointing to CloudFront, an S3 bucket to hold the contents, an S3 bucket security policy which restricts access just to CloudFront... well, it's complex and easy to misconfigure.

In terms of pricing, you can store 1GB in S3 for a year for a fraction of a dollar. The majority of the cost comes from CloudFront. Unless you have serious traffic, this is extremely cheap:

The interface (just put files in S3) suits me. I have a site where I deploy and invalidate the CloudFront cache in a GitHub Action: https://github.com/lifebeyondfife/whisky-menu/blob/master/.g...

It's probably cheaper
