US Patent 9894067 Cross-region roles

Techniques for using short-term credentials with access roles across regions are described herein. A request to assume a role associated with resources in a first region is received by a user in a second region. The request, which is digitally signed with credential associated with the user in the second region causes the generation of a short-term session credential that includes a session key and that can be used to assume the role. The user in the second region then assumes the role and, accordingly, can use the short-term session credentials to access the resources in the first region.
