What is Virtualization?



What is Virtualization?

Virtualization is the act of creating a virtual version of something- computer hardware, storage and network.
It allows for the distribution of a machine’s capacity among multiple user environments.
Traditionally, it was easier and more reliable to run individual tasks on individual servers: a single server hosts a single operating system that runs a single task at a time. With virtualization, one can split independent tasks onto different hardware resources. Hence, hardware resources are utilized to their maximum capacities with multiple tasks .
The technology that enables virtualization is called the hypervisor- it gives multiple users simultaneous access to perform batch processing.
Most enterprises have single-vendor IT stacks that don’t allow their legacy applications to run on a different vendor’s hardware. With virtualization, companies can partition their servers and run multiple operating systems and versions. Hypervisors sit on top of an operating system (like a laptop), or be installed directly onto hardware(like a server). Companies such as VMware and Citrix have niche HyperV products that enable virtualization capabilities in organizations.

Let’s start with a brief history of the evolution of application deployment. Traditional Application Deployment Era: In the traditional environment, organizations used to run applications on physical servers. There was no way to define resource boundaries in a physical server and this caused resource allocation problems. For example, if multiple applications ran on a physical server, there were instances where one application would take up most of the resources, and as a result, the other applications would underperform. A solution for this was to run each application on a different physical server. But this had a problem- it gave rise to many physical servers that were not scalable. As a result, resources were underutilized, and it was expensive for organizations to maintain many  physical servers . This problem gave rise to a solution: Traditional Virtual Machines. Figure 1: Traditional Architecture vs Virtual Architecture Virtualization Era:  Virtu...

The challenges of these past few months have transformed our workplaces in numerous ways. More recently, a Gartner survey had reported that 88% of organizations have asked employees to work-from-home and nearly all organizations (97%) have canceled any work-related travel. Work-from-home, therefore, has become the new norm of the workplace today. While the workplace shifts to different environments, business continuity must continue. Businesses should not suffer from a remote work environment. Having the best virtual workplace environments helps to bridge this gap.  However, this is not always convenient. A remote worker faces various challenges. Common complaints include inaccessibility to essential applications and files, network connectivity,  security  threats, lack of essential devices, and low performance. This means there is a need in organizations to increase the capacity, capability, manageability, and visibility of a remote worker so that the te...
