Abstract
Techniques for upgrading virtual appliances in a hybrid cloud computing system are provided. In one embodiment, virtual appliances are upgraded by deploying the upgraded appliances in both a data center and a cloud, configuring the upgraded appliances to have the same IP addresses as original appliances, and disconnecting the original appliances from networks to which they are connected and connecting the upgraded appliances to those networks via the same ports previously used by the original appliances. In another embodiment, upgraded appliances are deployed in the data center and the cloud, but configured with new IP addresses that are different from those of the original appliances, and connections are switched from those of the original appliances to new connections with the new IP addresses. Embodiments disclosed herein permit virtual appliances to be upgraded or replaced with relatively little downtime so as to help minimize disruptions to existing traffic flows.
