The primary driver was the potential for server consolidation: virtualization allowed a single server to cost-efficiently consolidate compute power on multiple underutilized dedicated servers. The most visible hallmark of a return to the roots of computing is cloud computing , which is a synonym for data center based computing (or mainframe ...
Virtual private server, a method of server hosting using virtual machines; Virtual hosting, a method that servers such as webservers use to host more than one domain name on the same computer. Virtual hosting service, a form of web hosting service where more than one instance of the same web server is hosted on a single physical server.
A virtual private server (VPS) is a virtual machine sold as a service by an Internet hosting service. [1] The term "virtual dedicated server" (VDS) has a similar meaning.A virtual private server runs its own copy of an operating system (OS), and customers may have superuser-level access to that operating system instance, so they can install almost any software that runs on that OS.
Virtual server: Shares hardware and software resources with other virtual servers. It exists only as defined within specialized software called hypervisor. The hypervisor presents virtual hardware to the server as if it were real physical hardware. [11] Server virtualization allows for a more efficient infrastructure. [12] Any networked ...
In OS-level virtualization, a physical server is virtualized at the operating system level, enabling multiple isolated and secure virtualized servers to run on a single physical server. The "guest" operating system environments share the same running instance of the operating system as the host system.
Server virtualization: Multiple virtual servers could be run on a single physical server, in order to more fully utilize the hardware resources of the physical server. Duplicating specific environments: A virtual machine could, depending on the virtualization software used, be duplicated and installed on multiple hosts, or restored to a ...
Virtual hosting is a method for hosting multiple domain names (with separate handling of each name) on a single server (or pool of servers). [1] This allows one server to share its resources, such as memory and processor cycles, without requiring all services provided to use the same host name.
A virtual directory or virtual directory server (VDS) in this context is a software layer that delivers a single access point for identity management applications and service platforms. A virtual directory operates as a high-performance, lightweight abstraction layer that resides between client applications and disparate types of identity-data ...
