What Is VMware vSphere? vSphere vs. ESXi vs. vCenter
VMware vSphere is the platform that unifies ESXi and vCenter into a complete solution for running and managing virtual machines. VMware vSphere is not a single product, but a full virtualization platform and product suite that includes ESXi, vCenter, and other tools for managing workloads. It provides the foundation for running virtual machines (VMs) on a hypervisor and gives IT teams the ability to centralize management across multiple servers, clusters, and applications.
