Also, just a nice mention for anyone considering Amazon’s Cloud service. Check out Rackspace’s Server Cloud. At the moment, the only things I’ve noticed that were missing was the ability to view/change DNS entries via the API and adding text records to the DNS; however, they tell me that’s coming soon. The other big difference is that with Amazon’s service, you have to save the image each time you restart (thus, you need to pay extra for attached storage if you want to use a database and not lose data). Rackspace’s are all stateless, so they’re basically like a VPS, but slightly neater.

But, back to the article =P If you only need hosted files and the like, such as this article mainly focuses on, Amazon’s S3 or Rackspace’s File Cloud are great choices.
