The term “virtualisation” refers to the possibility to abstract the hardware components of an ordinary computer in order to make them available to software in the form of virtual resources.
This process allows for installing one or several different operating systems on the same server dividing it into virtual machines.
One advantage of server virtualisation is that such server has all the potentials and features of a physical server while the resources are shared by all the virtual machines.
Multitasking systems allow each virtual machine to have its own hardware logically distributed and to have its own operating system and dedicated programs, all of these being logically separated from the other virtual machines.
The transition to a lower number of servers reduces the management costs of several physical machines. The VMware technology separates software from hardware, thus making it possible to run operating systems and applications on a single computer with substantial improvements in terms of efficiency, availability, flexibility and management.
The use of virtualisation for a broad range of mission-critical applications thus contributes to:
- Reducing the TCO (Total Cost of Ownership)
- Enhancing business agility
- Simplifying the management of systems
- Enhancing energy efficiency
