using a lower number of physical servers reduces hardware maintenance). It also utilizes resources to the fullest so it can also save on operational costs (e.g. First, less hardware is required so that alone saves a business money. Server virtualization also reduces costs. For example, it lets each virtual server run its own operating system and each virtual server can also be independently rebooted of one another.
Paravirtual machine: A virtual machine mode in which operating systems do not require complete emulation of hardware devices. The physical server and single instance of the operating system is virtualized into multiple isolated partitions, where each partition replicates a real server. Operating system-level virtualization: A type of server virtualization technology which works at the OS layer. Virtual machine: A self-contained operating environment that behaves as if it is a separate computer. There are several ways to create a virtual server, with the most common being Instead of requiring a separate computer for each server, dozens of virtual servers can co-reside on the same computer. Virtual Web servers are a very popular way of providing low-cost web hosting services. One common usage of this technology is in Web servers.
#OS X SERVER VIRTUALIZATION SOFTWARE#
Software is used to divide the physical server into multiple virtual environments, called virtual or private servers. In server virtualization the resources of the server itself are hidden (or masked) from users. Server virtualization is defined as the partitioning of a physical server into smaller virtual servers. This article defines two of the most common virtualization technologies: server virtualization and desktop virtualization, and explains the differences between them. In computing, virtualization means “to create a virtual version of a device or resource,” however many computing devices and technologies can be virtualized, including a server, desktop, storage, network, or even an operating system. Server virtualization and desktop virtualization can be a confusing topic if you don’t know the inherent differences between the two virtualization technologies.
