Yeah holy crap why is cloud formation so terrible?

I do get where you're coming from, but I don't agree. With the CF+S3 combo you now need to choose which sharing mode to work with S3 (there are several different ways you can link CF to S3). Then you have the wider configuration of CF to manage too. And that's before you account for any caching issues you might run into when debugging your site.

If you know what you're doing, as it sounds like you and I do, then all of this is very easy to get set up (but then aren't most things easy when you already know how? hehe). However we are talking about people who aren't comfortable with vanilla S3, so throwing another service into the mix isn't going to make things easier for them.

S3 is actually quite expensive compared to the competition for both storage costs and egress costs. At a previous start-up, we had terrabytes of data on S3 and it was our second largest cost (after GPUs) and by some margin.

For small scale stuff, S3s storage and egress charges are unlikely to be impactful. But it doesn’t mean they’re cheap relative to the competition.

There are also ways you can reduce S3 costs, but then you're trading the costs received from AWS with the costs of hiring competent DevOps. Either way, you pay.

With CloudFront?

Yeah, your classic web hoster. Just today I uploaded a static website to one via FTP.
