What is the role of vSphere High Availability in a vSphere environment?

vSphere High Availability (HA) plays a crucial role in ensuring continuous availability of virtual machines in a vSphere environment. This feature automatically detects host failures and initiates the restart of virtual machines that were running on the failed host onto other operational hosts within the cluster. By leveraging HA, organizations can minimize downtime and maintain service continuity, which is essential for applications that require high availability.

While storage redundancy, managing network resources, and balancing resource allocation are important aspects of a virtual environment, they do not specifically relate to the primary function of vSphere HA. Storage redundancy would involve technologies like VMware vSAN or traditional RAID setups. Network resource management refers to how virtual networks and traffic are handled across a data center. Resource allocation balancing typically relates to distributed resource scheduling (DRS), which is focused on optimizing the workload across hosts rather than ensuring the availability of VMs after host failures.
