What is Virtualisation?

Virtualisation is the utilisation of technologies that create separation between computing resources, software and applications.
This allows the running of multiple applications through a centralised, controlled environment making efficient use of IT resources, thereby saving money, space and energy, among other benefits.
It is proved technology that is transforming the way IT is implemented and managed and is fundamentally enhancing the way a business operates.

Server Virtualisation

Server Virtualisation, the most common form of virtualisation, permits the management of multiple operating systems inside one physical server. The virtual servers are separated from the physical hardware by a virtualisation layer. The benefits of this are that it requires less physical servers, increases the security of the host server, allows it to schedule and allocate resources, and requires less maintenance.

Desktop Virtualisation & VDI

Desktop virtualisation is the running of desktop operating systems in a virtualized environment. A Virtual Machine is a self contained file, which can be moved and compressed, that is hardware independent. Desktop virtualisation separates the physical machine from the software

VDI refers to the delivery of a complete virtual operating system running on a dedicated virtual machine. This means that many people can use the same server at the same time without impacting each other and they will feel as if they are using their own desktop. Users may be geographically scattered but are all connected to the central machine by a proprietary local area network (LAN) or wide area network (WAN) or the Internet.

What is Application Virtualisation?

Application Virtualisation is the method of centralising application software and associated licences and delivering the application from the central machine to the virtual desktop.  The virtualised system monitors access to the application software to ensure that the number of concurrent licensed users is not exceeded.  Furthermore, regular reporting on licence usage allows any organisation to add to or reduce their numbers of the licences based on actual usage.  This is Tribune’s ‘Just in Time Licensing’.
