The benefits of virtualisation


Virtualisation as a technology is not new – in fact, it has been here since the 1970s. While initially pioneered on IBM mainframes, allowing the machines to run multiple operating systems on a single physical system with shared hardware resources, it is now available to anybody.


One of the biggest changes, when it comes to hardware, is how the face of the end user has changed – or rather the machine. In recent years, we went from using desk top computers to mobile devices ranging from laptops and tablets to notebook and smartphones. This created the perfect environment for virtualisation to flourish.


Over the last ten or so years, virtualisation has matured to become a core business technology that enables organisations to balance high availability and security against the need for flexibility, resource-sharing and efficiency, and consolidating the IT environment.

Benefits of OS virtualisation


1. Reduce physical space used by IT
Instead of using a server per operating system, you can have a single server that runs multiple operating systems – you save space as well as money, because you do not have to buy and maintain so many servers.

2. Save money
In addition to saving money that need not be spent on buying a lot of servers, you also save on the running costs and storage costs of the servers you don’t need to use anymore. You pay less for electricity, as there are fewer machines, which also lowers your cooling costs.

3. Use server more efficiently
Virtualisation makes making improvements on your server hardware easy and fast, which means that your IT is used more productively and you have a bigger return on investment.

4. Manage server more easily
There are fewer servers, so you need fewer IT technicians to maintain and service the infrastructure.

5. Easier capacity-planning
With all the tools available in the virtualised OS environment, it is easier to maintain because you have a clearer picture of how the environment is growing and how much RAM is needed to sustain this environment.

6. Easier and faster to deploy OS and servers
Virtual machines can be prepared ahead of time and imported if needed; they use the same template, which is faster and easier.

7. Backups are quicker and easier
Additionally, virtualisation ensures that backups can be recovered significantly quicker in disaster recovery, as data can be restored to any other device.


Virtualisation can increase IT agility, flexibility and scalability while creating significant cost savings. Workloads are deployed faster, performance and availability increases and operations become automated, which results in IT becoming simpler to manage and less costly to own and operate.
