Chapter 3
Installing and Configuring vCenter Server
In the majority of today's information systems, the client-server architecture is king. This standing is because the client-server architecture can centralize resource management and give end users and client systems simplified access to those resources. Information systems used to exist in a flat, peer-to-peer model, when user accounts were required on every system where resource access was needed and when significant administrative overhead was needed simply to make things work. That's how managing a large infrastructure with many ESXi hosts feels without vCenter Server. vCenter Server brings the advantages of the client-server architecture to the ESXi host and to virtual machine (VM) management.
