Virtualization Introduction – Part 1
In this article, you will know Virtualization Introduction and also the concepts of Virtualization Technology, and some of the platforms like vSphere and Microsft Hyper-V. We have few more leading Virtualization technologies available in the market like Red Hat and Citrix Xen, Oracle and IBM.
Virtualization Introduction :
Before going to discuss, let us see the reason for going to Virtualization. In this Leading Business Today’s challenges confronting the CIO’s and IT Managers are;
Cost-effectiveness of IT infrastructure and supporting new business initiatives , flexibility in adapting the organizational changes.
To overcome the above challenges,virtualization has introduced.
Virtualization is the process of creating a software which is based on representing something ‘virtual’ rather than physical. It can be applied to some of the applications, servers,Desktops, storages, and networks. It is the most effective way to reduce the IT expenses and is useful in various businesses. It is a fundamental technological innovation that allows the skilled IT managers to deploy creative solutions to overcome the business challenges.
- Single OS image in each.
- Tightly coupled are hardwares and softwares.
- Can run multiple applications on the same machine in order to create a conflict between two.
- Resources are underutilized.
- They are nonflexible and has a costly infrastructure.
- Independence of hardware operating systems and applications
- Virtualization machines are provisioned to any type of machines.
- Can manage the Operating system and applications as a single unit by enveloping’s them into virtual machines.
- Virtualization is a software technology that divides a physical resource into multiple virtual resources.It consolidates the physical resources and separates the operating systems from hardware and enables multiple operating systems and applications to share the resources on a single physical machine.The term “virtualization” has introduced in the 1960s. However, In those days there were no personal computers so, virtualization did not become a reality until the late 1990s. Then the companies realized that they could save money by moving from a physical to a virtual platform.
Some interesting facts about virtualization are:
- Saves money by reducing the number of servers consumed, and costs less to purchase and maintain
- Makes management, control, and inspection of VMs much easier than with the traditional servers.
- Gives you a flexible environment for various tests and more.
How do we get this virtualization?
For this, we have many options available, but some are the frontier in this domain they are VMware, Citrix, Microsoft, Red Hat, Oracle, and IBM.
Some of the products in this domain are:
1. VMware ESXi and VMware server
2. Citrix Xen
3. Microsoft Hyper-V
4. Oracle VM Server
5. Red Hat Virtualization (KVM)
6. IBM PowerVM
Here we will discuss a few words about VMware vSphere and Microsoft Hyper-V
1) VMWare vSphere: VMware is a server free virtualization for Microsoft Windows and Linux servers. This enables you to have a quick provision for a new server by dividing a physical server into multiple virtual machines. This virtualization platform is mainly useful for business especially for those who wants to optimize their technology assets.
2) Microsoft Hyper-V: Microsoft did not ignore the virtualization but they introduced Hyper-V as a virtualization platform in 2008, and they continuously releasing new Hyper-V and Windows server versions. Hyper-V is a hybrid hypervisor, which is installed from OS i.e, Adding of Windows wizard roles, However, during installation, it redesigns the OS architecture and becomes a next layer on the physical hardware.

After a brief description about the Virtualization, I am going to explain you about a few benefits of Virtualization, they are:
1) Save energy, Environmentally friendly
Migrating the physical servers over to virtual machines and centralizing them on to few physical servers
2) Reducing the data center footprints
In addition to this save more environments with a smaller energy of footprints, server centralizing with virtualization will also reduce the overall footprints of your entire data center.
3) QA or Lab environments
Virtualization allows you to build out a self-contained lab tested environment, operating on its own isolated networks
4) Faster or Fastest server provisioning
Server virtualization enables the elastic capacity to provide the systems provisioning and deployments.
5) Reduces the hardware vendor
Server virtualization abstracts away the concealed hardware and replaces with virtual hardware, data center managers, and owners increases lot more extensibility when it comes to the server provisions.
6) Increases the uptime
7) Improves the disaster recovery
8) Isolated applications
9) Extends the life of old applications
10) Help to move things to the cloud
