While ESX can provide the environment that represents a computer, there are
limitations regarding the types of resources made available. When planning a virtual
environment, only server nodes that communicate over the network should be
included.
Interaction with the virtual machines is normally performed through a dedicated
client to create, modify, start and stop the virtual machines. It also enables the
opening of a console to takeover the virtual machine.
VMware vSphere encompasses the VMware ESX(i) server with the advanced
functionality of VMotion, High Availability, Fault Tolerance and Storage Motion.
vCenter Server provides central administration of the ESX(i) servers. VMware
vSphere Client is a Windows application which is used to login to the ESX(i) server,
or the vCenter Server for administration purposes.
