AMAZON AWS
FedRAMP granted Amazon Web Services GovCloud (US) a Provisional Authorization to Operate in May 2016. However, if an agency chooses to use the Amazon Web Services GovCloud (US), it must create its own Authority to Operate letter to show that it is accepting the security risk associated with the cloud service. The FedRAMP program cannot make decisions for the IRS or accept risk on its behalf. Additionally, agencies are directed to provide a copy of the Authority to Operate letter to the FedRAMP program.
