Virtualisation

What is Virtualisation?
Virtualisation is essentially a set of software products; the workstation version installs this onto Windows or Linux and allows you to run numerous Intel-based operating systems on top of it. There is also a server line of products, aimed at allowing people to run large numbers of operating systems on a single physical machine, one version of which provides its own base operating system. Essentially, this allows you to run multiple Intel-based operating systems on a single physical machine.

Virtual machines are encapsulated into files, making it possible to save, copy and provision a virtual machine rapidly. Full systems (fully configured applications, operating systems, BIOS and virtual hardware) can be moved in seconds (from one physical server to another), for zero downtime maintenance and continuous workload consolidation.

Benefits of Virtualisation:

Partitioning - Multiple applications and operating systems can be supported in a single physical system. Servers can be consolidated into virtual machines on either a scale-up or scale-out architecture. Computing resources are treated as a uniform pool, to be allocated to virtual machines in a controlled manner.
Isolation - Virtual machines are completely isolated from both the host machine and other virtual machines. If a virtual machine crashes, others are unaffected. Data does not leak across virtual machines, and applications can communicate over configured network connections only.
Encapsulation - Complete virtual machine environment is saved as a single file; easy to back up, move and copy; standardised virtualised hardware is presented to the application - guaranteeing compatibility.

QuoStar has been working with server virtualisation technologies from the beginning. We are your ideal partner to deliver the results which you would expect from a successful implementation on Virtualisation.
