Virtualization, sometimes called hardware virtualization, describes a virtual machine that functions like a real computer. Virtual machines are different than emulators and simulators.
Basic Virtualization Terms
Some key terms related to virtualization:
- Host: The computer that runs the virtualization software.
- Guest: The virtual machine that runs on the host. A guest may have a different operating system than the host. Also called a VM.
- Hypervisor: The application that creates and manages virtual machines. Also called a VMM, or virtual machine manager.
- VDI: Virtual desktop infrastructure – a virtual computing environment in which end users work on virtual desktops. Users gain access to their virtual desktops using an RDP client.
Some brands worth noting:
- VMware: Develops the most widely used virtualization technology worldwide.
- VCE: Designs, builds, delivers, and supports converged infrastructure stacks that integrate VMware virtualization technology with EMC storage and Cisco servers and networking components.
Virtualization as Part of an IT Strategy
Organizations adopt data center virtualization because of the benefits it delivers to IT departments, application users, and the business's bottom line. Virtualization in the data center commonly includes:
- Server virtualization: The first type of virtualization to gain popularity, server virtualization allows for more efficient utilization of compute resources and an improved ability to launch applications quickly in response to business needs. Enterprise applications are generally well suited to run on virtual servers because demand for computing power fluctuates. For organizations that provide web application development services, development and testing time is reduced dramatically as various platforms and environments can be created instantaneously using the hypervisor's provisioning and snapshot utilities.
- Storage virtualization: Storage repositories require maintenance, such as routine indexing, archival, and backup, and also need a reliable data recovery method. With a myriad of storage devices spread across a network, management can be laborious. When an organization makes the transition to a virtual storage strategy, a hypervisor pools storage resources and facilitates centralized management.
- Desktop virtualization: A contemporary spin on the server-client model, this practice virtualizes the end user experience. With desktop virtualization, user applications and data reside on a central cluster of virtual servers, and an RDP client allows users to access their virtual desktops on a variety of devices. Desktop virtualization solutions provide improved performance, manageability, and security of desktop applications.
