Amazon AWS is one of the most powerful and popular cloud tools available. I've been thoroughly impressed with its scalability and it's ease of use, once it's established. I will strongly suggest speaking with or consulting with someone with previous knowledge of the toolset, or you can have a bill for several hundred or even thousand dollars on your hands for things that you weren't aware were running.
While it's cumbersome at first, one of the easiest tools to use is Amazon S3. It essentially provides you the capabilities to have your own CDN (Content Delivery Network). In this space, you can store website images, html, and various other non-executable types, as easily as you can upload an image to Facebook. The only caveat I would have about this awesome tool is that it absolutely requires that you setup and administer the CORS for each folder or group. With CORS, you can say who can retrieve these images (ex: yourwebsite.com is the only location that can request these images). Without this setup, it's very easy for your images to end up cached in Google and you pay the bill for site crawls, users sharing an image, etc.
Otherwise, it's a great tool and as an Enterprise Consultant, I haven't seen an easier to use option to date.
