ApplicationHA-initiated reboot works independently of VMware HA functionality. It is not intended to replace VMware HA. It is useful in cases where there is a need to first bring down other healthy applications and dependent components before actually restarting the virtual machine and also in VMware virtualization environments where VMware HA is not available.

ApplicationHA-initiated reboot complements VMware HA by offering an additional layer of control that helps in building customized application management and recovery plans in virtualization environments. ApplicationHA-initiated reboot can co-exist with VMware HA. You can configure both ApplicationHA-initiated reboot and VMware HA as part of your recovery plan. ApplicationHA-initiated reboot can act as the first line of action against application failures. If a graceful restart does not resolve the application failures, then depending on the reboot configuration settings, ApplicationHA stops the application heartbeat and VMware HA then takes control of the virtual machine.
