The availability of the management functions of an environment becomes more critical in environments like those that support virtual desktops or self-service provisioning. In these environments, if the vCenter Server is unavailable, so is the ability to provide the provisioning of services.
If the environment does not provide these types of services, the ability to manage the environment, especially during a failure or disaster, is also critical. How can you troubleshoot an issue with a virtual machine (or a group of virtual machines) if the primary tool that is used to manage the environment is unavailable?
