In some embodiments, a first server system of a cloud service can receive a bearer token for accessing the cloud service. The bearer token can be generated based on authenticating a remote client in communication with the first server system. The first server system can determine that a resource of the cloud service is hosted by a second server system of the cloud service rather than the first server system. The resource can be identified using the bearer token. The first server system can provide the bearer token to the remote client along with redirect information for accessing the second server system. The second server system can in respond to receiving the bearer token from the remote client by establishing a session with the remote client. The remote client can access the resource via the session with the second server system.
