Explanation:

Virtualization layer. This layer provides the idealized hardware environment and virtualization of underlying physical resources to the virtual machines. It includes the Virtual Machine Monitor (VMM), which is responsible for virtualization, and VMkernel. Hardware interface components . The virtual machine communicates with hardware such as CPU or disk using hardware interface components. These components include device drivers, which enable hardware-specific service delivery while hiding hardware differences from other parts of the system.
User interface. Administrators can view and manage ESX Server hosts and virtual machines in several ways.
A Virtual Infrastructure Client (VI Client) can connect directly to the ESX Server host. This is appropriate if your environment has only one host. A VI Client can also connect to a VirtualCenter Management Server and interact with all ESX Server hosts managed by that VirtualCenter Server. The VI Web Access Client allows you to perform many management tasks using a browser-based interface.The service console command-line interface is used only rarely. Starting with ESX Server 3.0, the VI Client replaces the service console for most of the interactions. (Commands have changed since previous versions of ESX Server.)
