Abstract: For a communication channel having a first endpoint in a customer on-premise network and a second endpoint on a primary host machine in a cloud service provider infrastructure, the primary host machine determines a change in a state information of the communication channel and identifies a backup host machine for the communication channel. The primary host machine causes the change in the state information to be replicated to the backup host machine, wherein the replicated state information stored by the backup host machine is usable by the backup host machine after a failover causes the backup host machine to become the second endpoint of the communication channel.
