COMPUTING SYSTEM AND RELATED METHODS PROVIDING CONNECTION LEASE INFRASTRUCTURE WITH GATEWAY APPLIANCE FAILOVER

Abstract:

A computing system may include a plurality of Point of Presence computing devices (PoPs) configured to provide access to a computing network(s), and a plurality of gateway appliances. The gateway appliances may be configured to relay communications between client devices and virtual delivery appliances to provide the client devices with access to virtual sessions. The gateway appliances may route client device communications through the PoPs based upon gateway connection tickets, and may also generate the gateway connection tickets including a payload encrypted with a symmetric encryption key, and a plurality of different versions of the symmetric key encrypted with different public encryption keys of the PoPs. The PoPs may be further configured to use their private encryption keys to decrypt the encrypted symmetric key, use the decrypted symmetric key to decrypt the payload, and permit routing of the client communications based upon the decrypted payload of the gateway connection tickets.
