A virtual server refers to a network server located in an offsite data center. As such, it can be shared by several users, all of whom have varying levels of control over the server. Using it allows copying resources onto virtual machines (VMs) within a user’s premises. Virtual machines are, of course, computers that mimic dedicated hardware or software.
Virtualization is often done to gain access to higher-capacity servers’ processing capabilities at lower costs than maintaining and running an internal data center. A virtual server can increase an organization’s server capacity by over 80% as well.

A virtual server mimics the functionalities of a physical server. In general, virtual servers use a hypervisor, an OS that allows the creation and operation of several VMs. The hypervisor allows multiple users in an organization to use the same resources stored in their virtual server at the same time. It also enables organizations to distribute processing workloads to numerous virtual servers, depending on their subscription.
Types of Virtual Servers
Virtual servers come in various forms such as:
- VM model: Most virtual servers for virtualization purposes use hypervisors, which allows users to use multiple operating systems (OSs).
- Paravirtual machine (PVM) model: These virtual servers are highly similar to those employed in fully virtualized setups. But the process they follow involves using a recompiled guest OS running on top of a hypervisor operated by the host OS. Like the VM model, users can also run several OSs on it.
- OS level: In contrast to the first two models, OS-level virtual servers can only use the OSs used by the host or administrator.
Benefits of Using Virtual Servers
Virtual server use is becoming mainstream due to its notable advantages over using physical servers for several reasons, including those listed below.
Virtual servers allow companies to increase their computing power without the need to acquire equipment and the space to put them in, which are expensive to maintain and operate. Using visual servers also lets them reduce their energy consumption.
Virtual server providers allow users to manage and control their resources remotely. Users can thus ensure that all resources hosted on virtual servers are compatible with their in-house applications. Centralized management also allows them to perform backup and recovery remotely.
If an organization’s office is located in a disaster-prone area, virtual server use ensures that it remains business as usual, as the actual servers are located elsewhere. That ensures business continuity and prevents unwanted downtime.
Independent User Environments
By using multiple virtual servers, IT teams can ensure uninterrupted business operations even as they test software. All other employees won’t have trouble accessing resources and suffer downtime when using applications. And because each user is issued his/her own account, none of his/her sensitive data is in danger of being seen or obtained by others on the network.
Every service subscriber can spin up new virtual servers anytime the organization needs additional processing power. And when these are no longer required, they can be easily removed, thus lowering costs.
In sum, virtual servers provide various benefits to facilitate business operations. In today’s digital age, companies that don’t have their own physical servers may need to use visual servers to ensure they’re always up and running.
