After a thorough examination of available options; we decided to use Amazon's Web Services to power the backend of our product. AWS was chosen for its technical capabilities, but we were also very (positively) surprised by the level of support and assistance we received from Amazon's technical staff and evangelists. The AWS staff was unbelievably supportive and knowledgeable and played an important part in our decision to use AWS. Our experience with AWS has shown that even if AWS doesn't have the feature you need at the moment, AWS will definitely have it shortly.
