Today Virtualization is the most talked about technology in the market. Today, I will be discussing some aspects of Virtualization.
What is Virtualization?
Virtualization is the simulation of one or more server environments on an actual server. It is a technology that is rapidly transforming the IT landscape and fundamentally changing the way that people compute.
Today’s powerful x86 computer hardware was designed to run a single operating system and a single application. This leaves most machines vastly underutilized. Virtualization lets you run multiple virtual machines on a single physical machine, sharing the resources of that single computer across multiple environments. Different virtual machines can run different operating systems and multiple applications on the same physical computer.
In its most technically advanced form the virtualization software called the hypervisor creates a layer of abstraction between the virtual servers and the native hardware. The hypervisor can run several virtual instances of multiple operating systems at the same time and the virtual servers need not be aware they are running in a virtualized environment.
How Does Virtualization Work?
The virtualization platform is built on a business-ready architecture. Use free software such as VMware (Microsoft)/VirtualBox (Sun Microsystems) to transform or “virtualize” the hardware resources like CPU, RAM, hard disk and network controller—to create a fully functional virtual machine that can run its own operating system and applications just like a “real” computer.
Each virtual machine contains a complete system, eliminating potential conflicts.
Virtual Box/VMware virtualization works by inserting a thin layer of software directly on the computer hardware or on a host operating system.
This contains a virtual machine monitor or “hypervisor” that allocates hardware resources dynamically and transparently.
Multiple operating systems run concurrently on a single physical computer and share hardware resources with each other.
By encapsulating an entire machine, including CPU, memory, operating system, and network devices, a virtual machine is completely compatible with all standard operating systems, applications, and device drivers.
Benefits of Virtualization?
The virtualization technology helps the organizations in the following ways:
- Optimum utilization of hardware resources.
- Performance.
- Low maintainance cost.
- Consolidation of hardware.
I will be discussing the implementation of virtualization in my coming interactions.
