9.1.2.1. vCloud Networking and Security Edge
VMware vCloud Networking and Security Edge (Edge) appliances are self-contained environments that are stateless in nature. There is a “health check” API call that can be made to an Edge appliance to determine if it is functioning correctly. If the API returns negative, initiate a reboot of the Edge device. At the time of reboot, configuration information is updated from the VMware vCloud Networking and Security Manager™, and the Edge device continues to function properly.
