A less seen cost is for the various operations.

Regularly pushing lots of small files on S3 can get expensive. $1/200k files ($0.005 per 1k PUT requests).

Not to mention the minimum file size charge, which I think was a few kb per file in infrequent access S3.

Thanks, I'd not considered that one before, I'll make sure to keep an eye on that.

IA is only applicable for items that are 128kb or larger in size. Also Glacier adds 32kb of glacier data to each object as well as 8kb of standard tier storage per object. S3 is really inefficient for huge numbers of small files.
