What Is Virtualization?
There are many forms of virtualization. Three popular types are Desktop Virtualization, Server virtualization and Memory virtualization. Each type has its own advantages and disadvantages.
In this post, I will discuss Desktop Virtualization which has many benefits for both business and the consumer.
To begin, let us explore what virtualization is.
A brief definition of virtualization is “The practice of using a virtual computer that is like what one would have if the computer was not a virtualized computer”. Now we can see what virtualization is not. It is not sharing a physical computer or a resource. With Desktop Virtual there is no difference between the physical processor on one system and another system that use the same virtualization platform. As with any other type of virtualization it is all about resources and how they are shared.
A good example of the benefits of Hardware Virtualization is with servers. With this form of virtualization, there are two methods of operation. One method is where multiple physical servers are all operating with the same operating system. The other method is where one single machine is running virtual servers side by side on the same hardware.
With the introduction of Cloud Virtualization, there are two ways to look at Desktop Virtualization. The first way is with single machines and one single instance of the virtualization platform. With this method multiple OS level virtualization is possible. Another way to think of Desktop Virtualization is with multiple virtualization platforms on the same OS. This is what is commonly known as Cloud VMS.
Both of these forms of Desktop Virtualization are extremely useful for businesses and people that need a robust server and network infrastructure. Storage is an extremely important feature of most server virtualization solutions. Controlling access to storage can be extremely difficult in the case of a single OS. With cloud based Storage VMS users can establish a hierarchy of servers, storage and network virtualization allows clients to have access to only what they require.
The role of hypervisor
The hypervisor is also extremely important for data centers and Desktop Virtualization. The hypervisor is what actually controls the software of the virtual machines. There are two types of supervisors currently available VDI and SaaS. The traditional VDI is being replaced by newer and more efficient virtualization offers like Cloud VMS.
The other type of hypervisor is the CPU virtualization. CPU virtualization is used with a specific embedded processor. The advantages of CPU virtualization over others include better utilization of a given chip’s resources, better utilization of cache and shared memory resources. The only disadvantage of CPU virtualization is the cost of ownership, because each machine needs to be purchased for each virtualization solution. This leads to significant cost savings in the long term.
Many businesses are moving towards virtualization because they provide a complete solution for their businesses. If your company is looking into ways to implement virtualization then consult with a cloud computing expert that can walk you through the process. Whether you are looking to virtualize your desktops, laptops or server there are many options available for you.
Virtualization allows you to run multiple virtual machines on a single piece of hardware. The concept behind virtualization is that multiple virtual machines can run on any piece of hardware that has a hypervisor that supports it. Some examples of popular hypervisor tools include Xen, VMware and Hyper-v. These programs help the user to create a virtual machine that works with their operating system. The virtualization programs allow multiple virtual machines to exist within one physical server.
Cloud computing allows users to use the same hardware on-demand. Cloud computing is very similar to cloud data centers except for the fact that users do not have to own the physical machines. They pay on-demand for storage, memory and processors. The cloud servers can be scaled as needed when it comes to meeting demand from requests placed by end-users.
IBM is a leading service provider in the private cloud and virtualization space. Many of IBM’s customers are currently leveraging their IBM Bluemell technology and IBM Virtual Systems (by vps) in order to build and manage their virtual infrastructure. Software as a service is also called Software as a Service, SaaS, and is a model that is based on the idea that a business can deploy applications as a service (SaaS) on-demand from an existing development platform, instead of having to develop those applications from scratch.
This enables companies to eliminate the cost of deploying development platforms and allows them to utilize high quality resources at a very low price per unit. IBM has recently announced a new software as a service (SaaS) platform called IBM Cloud.
In a general sense, virtualization requires two things: a hypervisor, which acts as the software interface between a client system and a remote server, and a host OS, which provides the software drivers and executes programs on the hypervisor. A supervisor allows a user to create a virtual environment on a hardware virtual machine, and a host OS provides applications, storage devices, networking, and memory services that make up the virtual environment. While virtualization can be performed on bare metal, or in a virtual environment, most VDI solutions run on virtualization software such as VirtualBox, Xen, VMware, and Citrix.
There are many benefits to virtualization, including support for multiple operating systems, better resource allocation and cost control, better quality for applications and virtualization of the data center.
