What is virtualisation? It is often found that enterprise servers are operating significantly below their physical capacity. The operating speeds of current processor designs are such that they are outstripping the demands of the operating systems and running applications.
Virtualisation makes it possible to run multiple operating systems and multiple applications on the same computer, at the same time. Running many instances of operating systems and applications on one server, or server array, increases the utilisation and flexibility of hardware. Capacity not currently being used by one virtual server is available for use by another, greatly reducing wasted CPU capacity.
In practice, it is possible to raise the utilisation level of physical servers significantly, allowing maximum benefit from each server purchased. In addition to energy  savings and lower capital expenses due to more efficient use of your hardware resources, you get high availability of resources, increased security, easy scalability and improved disaster recovery processes.
Business benefits Virtualisation is a technique for hiding the physical characteristics of computing resources from the way in which other systems, applications, or end users interact with those resources. This includes making a single physical resource (such as a server, an operating system, an application, or storage device) appear to function as multiple logical resources; or it can include making multiple physical resources (such as storage devices or servers) appear as a single logical resource.

When you require more processing and/or more virtual machines, it is as simple as plugging in another node. No node OS or software setup is required - NEBULA Cluster Controller manages everything for you. The Cluster Controller also takes hardware problems out of the equation by automatically redistributing the load over the other nodes in the cloud if one node goes down.
