Are there any cost advantages to hosting a static site on S3+Cloudfront when compared to other services?

My first thought when reading this blog was that you can get the same results by placing your static content in an Nginx docker container and pushing it to ECS or Triton.

The docker container tagging would also avoid the rollback limitations mentioned in the article.

AWS offers so many ways to accomplish the same things, it's hard to figure out which solution is the most cost effective.
