Virtualization is the technology that enables the user to perform functions in a virtualized environment. Virtualized environment implies that you might be using some resources in the virtual form that need not necessarily be physically present around the user. Let us see an example to make things clear.

Let us assume that you are using a virtual server for your business process. What it means is that you are using a small part of a physical server. The server that you access performs like a physical server with dedicated resources, but in a virtualized environment, multiple users can share the same physical server simultaneously. This process is called server virtualization. Some other forms of virtualization include network, data, desktop, and storage.

Virtualization proves beneficial for customers as well as the hosting providers. All types of hosting providers such as dedicated, shared, colocation or cloud host the servers in the data centers that deploy virtualization in their infrastructure to save revenue, space, and power.

So, how is virtualization helpful for businesses as well as the hosting providers? There are various aspects of virtualization that have proven advantageous for diverse industries. Let us discuss some of these critical aspects.

Cost Reduction

When hosting an app or storing data on a server, you can analyze the type of processor you want, the OS you want to install and the specifications that go with it.  However, for some websites or applications, the specifications required are a bare minimum.

Let us look at it this way. If you are living in a 4-bedroom apartment, the space you are acquiring is more than your requirement. Consequently, you are paying for the entire apartment. If you share the apartment with 3 other individuals each acquiring one bedroom, the rent of the apartment will be shared by the four of you reducing your rent to one-fourth of what you were paying.

Before virtualization, the small and medium businesses had to buy or rent the entire physical server to host their process. They had to pay for the total resources even if they did not utilize all the resources. Moreover, if the server was owned, the maintenance of the server added some additional costs such as cooling and power equipment, cabling, etc.

With Virtualization, a single physical server can be shared among many business processes. Hence, they have to pay as per usage and not a penny more.

Space Optimization

Virtualization helps businesses as well as hosting providers to optimize their physical space. As the hosting providers can divide a server into multiple Virtual Machines (VM), with each VM being used by individual businesses, the number of physical servers required reduces considerably.

optimize space

For instance, if two businesses are utilizing only half of their resources on two separate physical servers, because of virtualization, both can share a single physical server and still function properly reducing the number of servers by half.

Hence, if you own a data center, you can provision more servers in the same physical space and grow your business even further.

Flexible Operation

Virtualization offers the businesses a more flexible operation. As it separates the software from the underlying hardware, the servers can host multiple operating systems and applications.

You can host your business process on VMs, and each VM can have its own operating system and applications. Each VM acts as an independent server which means that each customer hosted on separate VMs can have it configured as per the business requirement.

Moreover, with application virtualization, the applications that are installed on one VM can be replicated to all the VMs in a matter of minutes.

In a conventional scenario, you install the operating system on the server, and both are bound to each other. However, in virtualization, a hypervisor is installed on the server first, and the VMs are created by it. Hence, there can be as many operating systems as the VMs.

Scalability

Virtualization, when integrated with the cloud environment, offers a highly scalable solution for businesses. Although the cloud encompasses multiple technologies, virtualization is the most important among them.

In a cloud environment, a cluster of servers can function in synchrony with the resources of each pooled together. You can host multiple Virtual Machines on the servers possibly with different specifications.

Generally, when you host an application on a physical server and utilize all the resources, the server hardware has to be replaced manually. However, as the VMs are virtual, they can be upgraded almost instantaneously.

Resource Overallocation

What if you were told that virtualization makes it possible to use more resources than are actually available. It can happen with a process called resource overallocation.

Imagine you have a server with 64 GB RAM and you create 10 VMs with 8 GB RAM each. As per calculations, the total RAM allocated to VMs account to 80 GB which is more than the total RAM of the server. How is it possible?

overallocation of ram

Well, the total RAM utilization occurs, when all the VMs are utilizing their full capacity at the same time. Practically speaking, that is never the case.

In a virtualized environment, the total RAM utilized at any given time is calculated rather than the total RAM allocated.  Hence, at any point in time, if the total RAM utilization is less than 64 GB, the server will function properly.

Easy Provisioning

The VMs can be provisioned easily as compared to the physical servers. Due to the virtual nature, a VM can be added or deleted on the server as per the requirement. Moreover, the operating system and applications can be installed almost instantly.

For instance, in Virtual Desktop Infrastructure, virtual desktops are provisioned to the users that can be accessed remotely. The virtual desktops are generally hosted in remote data centers. These hosted virtual desktops can have their own set of specifications, operating system, and applications.  

Imagine you have an office with 200 desktop PCs. Each PC must be configured manually with the installation of an operating system to the upgrading of applications. Moreover, if the number of employees increases, new desktops have to be configured.

As Virtual Desktops are mainly hosted on VMs, the applications and operating system can be replicated to the desktops simultaneously.

Less Hardware, Fewer Problems

Working in a virtualized environment leads to a reduction in the hardware count. As the hardware requirement reduces, so does the hassles associated with it.

As the VMs can be provisioned very conveniently, the size of the IT team required can be cut down significantly. Moreover, the tedious task of hardware replacements is not a factor.

For businesses, the cumbersome IT issues have proven to be a bottleneck in an otherwise streamlined process. All these issues can be eliminated by adopting a virtualized environment.

Let’s Sum it Up!

Virtualization is a boon for businesses as well as hosting providers. It reduces the cost of hardware maintenance and replacement. Multiple processes can be hosted on a single server optimizing the space requirements for hosting providers. As there is less hardware to deal with, you can reduce the support team considerably. It reduces time and effort of setting up new servers as you can provision the VM instantly.
