In order to understand why you should virtualise, you first need to understand what virtualisation is.

Virtualisation uses software that simulates hardware functionality in order to create a virtual system. This practice allows IT organisations to operate multiple operating systems, more than one virtual system and various applications on a single server. The benefits of virtualisation include greater efficiencies and economies of scale.

A virtual machine is created when software separates the operating system and its applications from the physical computer hardware. This software process is called a hypervisor, which allows a physical machine to host multiple virtual machines as guests, sharing various computing resources such as memory, network bandwidth and CPU cycles. Hypervisors can sit on top of an operating system or be installed directly onto hardware, which is how most enterprises virtualise. Hypervisors take your physical resources and divide them up so that virtual environments can use them.

What are the types of virtualisation?

  1. Virtual Machines — This is a computer file that looks and acts like a computer and works independently to the host.
  2. Virtual Memory — to ensure VMs work effectively, there must be a high level of virtual memory available. This helps applications to improve overall performance and store and receive data.
  3. Virtual desktop infrastructure —(VDI) is defined as the hosting of desktop environments on a central server. It is a form of desktop virtualisation, as the specific desktop images run within virtual machines (VMs) and are delivered to end clients over a network. Those endpoints may be PCs or other devices, like tablets or thin client terminals.
  4. Virtual applications — allows users to access apps without storing them locally and businesses to have more control over their usage.

So, why virtualise?

It’s cost effective. Virtualisation reduces the amount of hardware servers necessary within a company and data centre.

It can release assets, reduce overheads and operational fees, as well as decrease the need for multiple software licences.

Easier disaster recovery and quicker backups. Regular snapshots provide up-to-date data, allowing virtual machines to be feasibly backed up and recovered. Even in an emergency, a virtual machine can be migrated to a new location within minutes.

It’s good for the environment, with less server and storage requirements, there is less cooling required. When end of life comes, there are fewer units to dispose of.

Easier testing. Testing is less complicated in a virtual environment.

Improved productivity. Fewer physical resources results in less time spent managing and maintaining the servers.

Virtualisation provides companies with the benefit of maximising their output.


Before converting to a virtualised environment, it is important to consider the various upfront costs. The necessary investment in virtualisation software, as well as hardware that might be required to make the virtualisation possible, can be costly.

If the existing infrastructure is more than five years old, an initial renewal budget will have to be considered. Fortunately, many businesses have the capacity to accommodate virtualisation without spending large amounts of cash. Furthermore, the costs can be offset by collaborating with a managed service provider that provides monthly leasing or purchase options.

Software licensing considerations that must be taken into account when creating a virtualised environment.

Virtualisation is not only about cost reduction, by digitising, you can also provide much greater capability for the provision of IT services, especially in the context of high availability and business continuity.
