Cloud Computing 'The Benefit of Virtualisation - Part 5

Hi all,

On this post, let go through a few benefits of Virtualization that most IT Expert needs to know…

 Virtualization can increased the utilization of resources.

  •  It allows workload balancing and the avoidance of downtime because most Virtualization Technology supports for virtual machine (VM) live migration from one host to another.

  • It provides dynamic fault tolerance against software failures (through rapid bootstrapping or rebooting)

  • It provides hardware fault tolerance (through migration of a virtual machine to different hardware).

  •  It provides the ability to securely separate Virtual Operating Systems.

  • It provides the ability to support legacy software as well as new OS instances on the same computer.

  •  Virtualization also has benefits when working on development (including the development of OS): running the new system as a guest avoids the need to reboot the physical computer whenever a bug occurs.

What is server virtualization?

Server Virtualization is an effective tool of disaster recovery planning.

It minimizes hardware downtime and recovers data quickly.

During the implementation of Server Virtualization, company should consider the following:

  • Data protection (backups)

  • Recovery granularity

  • Restore performance

  • RTOs/RPOs

What is Workspace Virtualization?

Workspace Virtualization is a method of distributing applications to client computers by utilizing Application Virtualization, it can combine some major applications together into one inclusive complete workspace.

At a minimum, the workspace consists of everything above the OS kernel like applications, data, settings, and any other non-privileged operating system subsystems which is required to provide a functional desktop computing environment.

What is a Virtual Machine (VM)?

A virtual machine (VM) is a software implementation of a computer that executes programs like a real machine.

Virtual machines are separated into two major categories, based on their use and degree of correspondence to any real machine.

A system VM provides a complete system platform which supports the execution of a complete operating system.

An essential characteristic of a virtual machine is that the software running inside is limited to the resources and abstractions provided by the virtual machine.

Multiple virtual machines with different operating system can co-exist on the same computer.
