Linux-based Virtualization

Linux-Based Virtulization

During 2006 and 2007 the IT industry saw developments from Intel, AMD and Linux that led to Kernel-Based Virtual Machine Techniques becoming readily available.

The method

With Xen, virtualization deploys a hypervisor which oversees both host and guest operating systems. The resources on a typical Linux based host can be divided up into multiple virtual guest areas. Each of these can have a guest operating systems installed. Our virtualized server solution can run just about any OS.  However, in the case of Microsoft Windows, full hardware-simulation for virtualization must be used to accommodate the installation.

The benefits

The result is a machine with a robust Linux operating system, which as several individual virtual servers all running on a single physical machine. Each virtual machine has its own operating system, which can be as diverse as Windows 2003 server and Linux all running on the same physical server. Additionally, there can even be several versions of one particular OS, each independent and operating concurrently. This is an excellent way to accommodate older or unstable versions of business critical applications.
In each virtual space, operating system and applications run in isolation and independence. If an application fails and requires re-start or if an application requires upgrade, this can be accommodated while other virtual machines and the applications deployed on them continue to run.

Increased efficiency

The host operating system shares hardware resources through the hypervisor and manages the resource calls of each guest operating system.
Historically, with the traditional one server per physical machine configuration, most servers run at only ten to fifteen percent capacity and requires its own rack space, power and air conditioning.  When considering the waste involved with such scenarios, it makes sense to opt for a virtualized solution.  Just as server blades provided more efficient use of rack space, virtualization is poised to improve operational efficiency as well as flexibility of datacenter infrastructure.

Reduced down time

Reduced down time is another benefit. In a virtualized environment a single application stoppage has much less impact on other business critical applications.  Addtionally, virtualization can be leveraged for high-availability and business continuity.
