What is the primary benefit of using VMware HA within a cluster?

The primary benefit of using VMware High Availability (HA) within a cluster is the automatic restart of virtual machines after a host failure. VMware HA is designed to enhance the availability of applications by ensuring that if a physical host fails, any virtual machines running on that host are automatically restarted on other available hosts within the cluster. This minimizes downtime and ensures that services and applications remain accessible, thus enhancing business continuity.

While proactive resource allocation, real-time performance monitoring, and workload distribution are important aspects of a virtualized environment, they do not specifically address the core function of VMware HA, which is focused on recovering from hardware failures. The ability to automatically restart VMs helps organizations maintain operational efficiency and reduce the impact of downtime on business processes.
