Infrastructure Services

vSphere infrastructure services are the core set of services that allows you to virtualize x86 servers (see Figure 1-1). First, these services abstract the physical x86 hardware resources, such as CPU, memory, storage, and network adapters, into virtual hardware to create virtual machines (VMs). Next, these services enable vSphere to transform resources from individual x86 servers into a shared computing platform with several operating systems and applications running simultaneously in different virtual machines. Finally, the infrastructure services provide several sophisticated features to optimize resources in such a shared environment. Figure 1-1 provides an overview of all the services in vSphere 4.
