Server and Infrastructure Virtualisation

The introduction of virtualization technology presents a number of opportunities for driving capital and operational efficiency above and beyond the simple benefit of safe partitioning. VMware's customers have harnessed the power of virtualization to better manage IT capacity, to provide better service levels, and to streamline IT processes. We have coined a term for virtualizing the IT infrastructure–we call it the virtual infrastructure.

What is a Virtual Infrastructure?

In essence, a virtual infrastructure is a dynamic mapping of physical resources to business needs. While a virtual machine represents the physical resources of a single computer, a virtual infrastructure represents the physical resources of the entire IT environment, aggregating x86 computers and their attached network and storage into a unified pool of IT resources.

Structurally, a virtual infrastructure consists of the following components:

  • Single-node hypervisors to enable full virtualization of each x86 computer.
  • A set of virtualization-based distributed system infrastructure services such as resource management to optimize available resources among virtual machines.
  • Automation solutions that provide special capabilities to optimize a particular IT process such as provisioning or disaster recovery.

By decoupling the entire software environment from its underlying hardware infrastructure, virtualization enables the aggregation of multiple servers, storage infrastructure and networks into shared pools of resources that can be delivered dynamically, securely and reliably to applications as needed. This pioneering approach enables organizations to build a computing infrastructure with high levels of utilization, availability, automation and flexibility using building blocks of inexpensive industry-standard servers.
