Power, Scaling, Versatility at a Competetive Price

Amazon Web Services is a solid and powerful platform. As outlined before, there is nothing it can't do. Its free tier also allows you to try out a solution as a proof of concept before going to full implementation. The only things that stop it from a 10 rating is the web console that could be a little more user-friendly. Additionally, the IAM security model is immensely popular and granular but could use a little more documentation/support to assist those that aren't security experts.

Similar to the previous answer, Amazon Web Services is a solid and powerful platform.

Amazon Web Services is well suited for nearly any kind of web application or cloud-connected solution you are looking to build. Amazon Web Services provides various scaling options for nearly all of its services, so you can optimize your cost by not using too much power until necessary. Amazon Web Services has a rich API to all of its services, making it very flexible and powerful from a developer perspective. The web interface to manage resources is still a little outdated, so if you have clients that are reliant upon it, you may look into other options as not to intimidate them.
