sending the client an identification of each candidate session server in the determined set of two or more candidate session servers; and at each candidate session server in the determined set of two or more candidate session servers, after receiving a registration request from the client, creating an active registration for the client. ### Claim 6 (depends on 5) The method of claim 5, wherein determining a set of two or more candidate session servers for the client to register with comprises: for each of a plurality of available session servers in the cloud computing system, determining a response time between the available session server and the client; including available session servers having a determined response time below a threshold response time in the set of two or more candidate session servers; and excluding any available session server having a determined response time above the threshold response time from the set of two or more candidate session servers. ### Claim 7 (depends on 6) The method of claim 6, wherein the response time is based on any one or more of network latency between the client and the session server, network latency between the application server and the session server, or processing time at the session server. ### Claim 8 (depends on 1) The method of claim 1, further comprising: at each session server in the set of two or more session servers with which the client has an active registration, renewing the active registration on a periodic or semi-periodic basis. ### Claim 9 (depends on 1) The method of claim 1, wherein the communication session comprises at least one of a file transfer, a database query, a streaming media session, a voice communication session, a video communication session, or a messaging communication session. ### Claim 10 (depends on 1) The method of claim 1, wherein the method further comprises: after establishing the communication session with the client via the session server having the shortest response time of the set of two or more session servers with which the client has an active registration, monitoring one or more performance metrics of the communication session; and when one or more of the performance metrics of the communication session exceeds a corresponding performance threshold, transitioning the communication session to a different session server with which the client has an active registration. ### Claim 11 A method executed at a client, the method comprising: establishing an active registration for the client at two or more session servers of a cloud computing system, wherein each session server is configured to control one or more aspects of a communication session for an application associated with an application server; for each session server in a set of two or more session servers with which the client has an active registration, determining a current response time between the session server and the client; and after the client has received a request to establish a communication session for the application associated with the application server, establishing the communication session for the application associated with the application server via the session server having the shortest response time of the set of two or more session servers with which the client has an active registration. ### Claim 12 (depends on 11) The method of claim 11, wherein establishing the communication session for the application associated with the application server via the session server having the shortest response time of the set of two or more session servers with which the client has an active registration comprises: sending, from the client to each session server in the set of two or more session servers with which the client has an active registration, a request to establish the communication session; and establishing the communication session via the first session server from which the client receives a response to the set up request for the communication session. ### Claim 13 (depends on 11) The method of claim 11, wherein the method further comprises: maintaining an active registration response time table at the client, wherein the active registration response time table comprises, for each active registration between the client and a session server, a current response time between the client and the session server;
