monitoring to further improve application uptime. vSphere App HA can be configured to restart an application service when an issue is detected. It is possible to protect several commonly used, off-the-shelf applications. vSphere HA can also reset the virtual machine if the application fails to restart.

Architecture Overview

vSphere App HA leverages VMware vFabric™ Hyperic® to monitor applications. Deploying vSphere App HA begins with provisioning two virtual appliances per vCenter Server: vSphere App HA and vFabric Hyperic. vSphere App HA virtual appliance stores and manages vSphere App HA policies. vFabric Hyperic monitors applications and enforces vSphere App HA policies, which are discussed in greater detail in the following section. It is possible to deploy these virtual appliances to a cluster other than the one running the protected applications; for example, a management cluster.

After the simple process of deploying the vFabric Hyperic and vSphere App HA virtual appliances,

vFabric Hyperic agents are installed in the virtual machines containing applications that will be protected by vSphere App HA. These agents must be able to reliably communicate with the vFabric Hyperic virtual appliance.
