virtual

What is virtual?

In computing, the term virtual refers to a digitally replicated version of something real, whether it's a machine, a switch, memory or even reality. It is distinguished from the real by the fact that it lacks an absolute, physical form. However, functionally it is no less real.

The replication, which is created with software, may not be an exact copy of the actual item, but it is similar enough in essence to be described as a digital rendition, and useful enough to support enterprise business needs.

What is virtual computing?

Virtual computing is the idea that one physical computer can act like many computers. It enables users to remotely access a computer from their local device. It also allows them to download and use more than one operating system, simultaneously perform multiple functions and get all the benefits of additional hardware and software without having to purchase or install them on their local system.

Users gain access to the remote computer via the internet through a wireless or network server, and log in via a specialized software. Once they log in, they can perform many tasks via their local device's keyboard, mouse or other tools.

Virtual computing is a real-time technology that enables users to remotely access:

Advantages of virtual computing

Virtualization is a paradigm in computing that is supported by the internet and numerous hardware and software solutions. It opens up many possibilities in IT and enterprise computing in terms of:

There are several benefits to using virtual computing. They are as follows:

Virtual computing helps expand the enterprise IT environment to users who are not in the same location as the resources they need to access. Allocating a computer's processes and resources to a virtual environment makes the system available for other processes and applications, which increases the overall efficiency of the system. It also frees up space on individual devices because users don't have to install, configure or store the assets they need as they can be accessed remotely and on-demand.

Virtual computing also improves the speed, accessibility and performance of IT operations and users. And resource-sharing through virtual computing eliminates the need to operate multiple computers and servers, which reduces cooling and power costs.

Applications of virtual computing

Virtual computing plays a crucial role in modern-day information technology (IT) architectures. It has a number of real-world applications, including:

Does virtual mean it's not real?

Just because something is virtual doesn't make it any less real. Virtual is more about the environment where online activities take place, rather than the activities themselves.

For instance, a virtual trade show refers to an event that takes place in a computer-based virtual venue rather than in a physical venue. The event lacks a physical form, but it is no less real than any regular event held in the "real" world.

Similarly, virtual learning enables students to remotely access learning resources in a virtual environment. They can view videos, communicate with other students and even participate in live lectures from their local device. Thus, they learn in a "virtual classroom," which doesn't have a physical form, but still exists for all practical purposes.

Also, explore common virtualization problems and how to solve them, virtual server management best practices and the benefits of containers on bare metal versus on VMs.
