Abstract
Systems are methods are provided for implementing cloud survivability which mitigates the loss of secure communication via a cloud orchestrated IPsec tunnel, due to a loss of connectivity to a cloud service. For example, devices can establish IPsec tunnels which are orchestrated by a cloud service, such as SD-WAN Tunnel Orchestration. Then, according to the disclosed cloud survivability techniques, if the connection to the cloud service fails, a cloud survivability phase can be triggered which fails-over from IPsec tunnel to a survivability tunnel. In some implementations, a method includes: determining, by an initiator device, whether there is a loss of connectivity of the initiator device or the responder device with a cloud service. Further, in response to determining that there is a loss of connectivity, automatically establishing a survivability communication link between the initiator device and the responder device.
