VMware vSphere® is a virtualization platform that forms the foundation for building and managing an
organization's virtual, public, and private cloud infrastructures. VMware vCenter® Server Appliance™ (vCSA) sits
at the heart of vSphere and provides services to manage various components of a virtual infrastructure like ESXi
hosts, virtual machines, and storage and networking resources. As large virtual infrastructures are built using
vSphere, vCenter Server becomes an important element in ensuring the business continuity of an organization.
vCenter Server must protect itself from a set of hardware and software failures in an environment and must
recover transparently from such failures. vSphere 6.5 provides a high availability solution for vCenter Server,
known as vCenter Server High Availability, or VCHA.
