The Information Services Virtual Hosting service provides a virtual server hosting environment.
It consists of a well managed physical environment which includes server hardware, storage and networking, and server virtualisation software, which allows many virtual machines to run concurrently on the same physical hardware.
It is designed to be a robust and performant service.
Server virtualisation supports more efficient use of physical server hardware. Virtualisation allows many virtual machines to run concurrently on the same physical server with appropriate resource controls ensuring that the application obtains the required performance. An application running on the virtual machine is indistinguishable from the same application running on a physical server.
