What is the difference between ESXi and vCenter Server?

• A. ESXi is a Type 1 hypervisor, vCenter Server is a management platform.
• B. ESXi runs on top of vCenter Server.
• C. vCenter Server is a hypervisor.
• D. They are the same.

Answer: (A)

ESXi and vCenter Server play different roles in a virtualized environment. ESXi is a Type 1 hypervisor that runs directly on physical hardware and hosts virtual machines. vCenter Server is a centralized management platform that connects to one or more ESXi hosts to manage them, provision resources, and enable features across a cluster. It is not a hypervisor and does not host VMs itself. In a typical setup you install ESXi on each server, then deploy vCenter Server to manage those hosts and coordinate capabilities like vMotion, high availability, and resource distribution. The idea that ESXi runs on top of vCenter or that vCenter Server is a hypervisor is incorrect, and they are not the same.
