Virtualization is an abstraction layer that decouples the physical hardware from the operating system to deliver greater IT resource utilization and flexibility.

Virtualization allows multiple virtual machines, with heterogeneous operating systems to run in isolation, side-by-side on the same physical machine. Each virtual machine has its own set of virtual hardware (e.g., RAM, CPU, NIC, etc.) upon which an operating system and applications are loaded. The operating system sees a consistent, normalized set of hardware regardless of the actual physical hardware components.

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

Virtualization was first introduced in the 1960s to allow partitioning of large, mainframe hardware -a scarce and expensive resource. Over time, minicomputers and PCs provided a more efficient, affordable way to distribute processing power, so by the 1980s, virtualization was no longer widely employed.

In the 1990s, researchers began to see how virtualization could solve some of the problems associated with the proliferation of less expensive hardware, including underutilization, escalating management costs and vulnerability.

Today, virtualization is in the forefront - helping businesses with scalability, security and management of their global IT infrastructure.

Benefits of Virtualization
Partitioning
• Multiple applications and operating systems can be supported within 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 the host machine and other virtual machines. If a virtual machine crashes, all others are unaffected
• Data does not leak across virtual machines and applications can only communicate over configured network connections
Encapsulation
• Complete virtual machine environment is saved as a single file; easy to back up, move and copy
• Standardized virtualized hardware is presented to the application - guaranteeing compatibility

Our technical team has developed "off the shelf" appliances to host multiple virtual servers allowing you to only purchase standard editions of the software licenses you use today.
We kept it simple. Our appliances allow you to do what you do today, adding consolidation benefits, load balancing and high availability.
Cost savings of around 30% year on year are achieved on licensing, hardware and support.
