    High Availability Overview

    To minimize the risk of downtime, WebApp Secure deployments have the ability to be placed in a Highly Available (HA) configuration. In this setup, an additional appliance is on stand-by in the event that the currently-active appliance goes offline. If this happens, the passive appliance is able to become the new active appliance automatically - without needing to restart the system. An HA configuration is similar to clustering, with the major exception being that the passive system has a copy of the services needed to take over when the master fails. WebApp Secure uses a Virtual IP (VIP) to float between the currently active system and the current passive system.

    Note: An HA configuration is only available on WebApp Secure dedicated hardware systems. It is not available in a Virtual Machine installation.
