Read the article. Amazon does not compete fairly. The company has friends in high places. Its hosting service is far inferior to what is provided by hosting services for the private sector and to what other hosting services who are cleared for federal work offer. There is no interface with AWS, just a Linux prompt (there is some sort of third party interface, but it is not available to government agencies). The contractor has to hire a subcontractor with boatloads of our money to set up the full stack and create the interface individually for each site. Other hosting services approved for fed work, such as Blackmesh and Acquia, provide full service hosting with the stack installed and maintained, plus a very good interface. The Amazon effort to handle hosting for all of DoD is a massive scam. If you don't believe me, work on some DoD web sites and find out.
