Application virtualization is a software technology that encapsulates computer programs from the underlying operating system on which they are executed. A fully virtualized application is not installed in the traditional sense, [ 1 ] although it is still executed as if it were.
The words host and guest are used to distinguish the software that runs on the physical machine from the software that runs on the virtual machine. The software or firmware that creates a virtual machine on the host hardware is called a hypervisor or virtual machine monitor. [2] Hardware virtualization is not the same as hardware emulation ...
Data virtualization software may include functions for development, operation, and/or management. [citation needed] A metadata engine collects, stores and analyzes information about data and metadata (data about data) in use within a domain. [8] [clarification needed] Benefits include: Reduce risk of data errors [dubious – discuss]
Virtualization software allows a single host computer to create and run one or more virtual environments.. Virtualization software is most often used to emulate a complete computer system in order to allow a guest operating system to be run, for example allowing Linux to run as a guest on top of a PC that is natively running a Microsoft Windows operating system (or the inverse, running Windows ...
The creation and management of virtual machines has also been called "platform virtualization", or "server virtualization", more recently. [2] [3] Platform virtualization is performed on a given hardware platform by host software (a control program), which creates a simulated computer environment, a virtual machine (VM), for its guest software ...
Full-system virtualization (Processor Core ISA + Hardware + External connections) Early embedded software development and integration (from driver to application), Multi-core software debugging and optimization Depending on the system characteristics and the software itself, ranges from faster than real time to slow [citation needed]. Yes Virtuozzo
This evolved into virtual machines, notably via IBM's research systems: the M44/44X, which used partial virtualization, and the CP-40 and SIMMON, which used full virtualization, and were early examples of hypervisors. The first widely available virtual machine architecture was the CP-67/CMS (see History of CP/CMS for details). An important ...
Desktop virtualization is a software technology that separates the desktop environment and associated application software from the physical client device that is used to access it. Desktop virtualization can be used in conjunction with application virtualization and user profile management systems, now termed user virtualization , to provide a ...
