TRANSPARENT HIGH AVAILABILITY FOR CUSTOMER VIRTUAL MACHINES ACHIEVED USING A HYPERVISOR-BASED SIDE CHANNEL BONDING AND MONITORING

Abstract:

Systems and methods for transparent high availability for customer virtual machines using a hypervisor-based side channel bonding and monitoring are disclosed herein. The method can include creating a network path bond between at least one compute instance and a plurality of Network Virtualization Devices ("NVD"), the network path bond including a plurality of network paths, each network path connecting the compute instance with the Virtualized Network Interface Card ("VNIC") of one of the plurality of NVDs, identifying a first one of the network paths as an active network path and a second one of the network paths as an inactive network path, performing a health check on the active network path, determining that the active network path failed the health check, marking the first one of the network paths as failed subsequent to determining that the active network path failed the health check, and identifying the second one of the network paths as the active network path
