Starting a substantial project. There will be 100s of images on the site. Few are part of the general design, but there are slide carousels, photos, etc.
I understand what S3 is, but I'm wondering what the specific value is of using it over local storage. There is plenty of room on the web host's server.
S3 isn't a CDN, right? Or will it replicate files across to other locations?
Should I expect S3 to be faster than local storage? And is my S3 bucket backed up elsewhere, should Amazon's servers crash?
