Most of our customers make extensive use of VMware virtualisation technologies to improve the reliability of their networks and reduce costs. For those who may not be familiar with virtualisation, we’ve prepared this brief guide to virtualisation and its 8 most important benefits.

What is virtualisation?
Virtualisation is a technology that allows you to run numerous operating systems on a single unit of server hardware at the same time. For example, if you currently have 10 physical servers, you could reduce them to 10 virtual servers running on a single physical server.
Benefits of virtualisation
There are many benefits of using virtualisation, with many relating to cost and reliability. We’ve summarised the 8 most important benefits below.
1. Reduces hardware costs
With virtualisation, you can convert physical servers to virtual servers. You can then run those virtual servers on a smaller number of physical servers. Fewer physical servers means less investment in expensive server hardware, racks and networking equipment.
2. Reduces vendor hardware lock-in
Virtualised servers are “hardware agnostic”, meaning that they are not tied to particular hardware. For example, you can migrate a virtual server running on an HP physical server to a Dell server in minutes, without any adverse impact. This might take several days with a physical server.
3. Improves uptime
Hardware failures are a fact of life. By implementing virtualisation, you can reduce the risk of downtime to almost zero. Many of our virtualised environments maintain a constantly up-to-date replica of critical servers between two physical servers. If a physical server fails, you can immediately switch over to the replica and keep working as normal, while the faulty server is repaired.
4. Improves disaster recovery
Fire, flood, earthquake or even theft. Disasters come in many forms. But you can be prepared. If disaster strikes, you can be up and running again in a fraction of the time, and with minimal or no data loss. Virtualisation can eliminate existential threats to your business.
5. Isolates applications
Some applications, particularly older ones, are not always friendly to other applications running on the same machine. Virtualisation allows these applications to run in their own isolated virtual machine. This eliminates incompatibility between your applications, and the need for additional hardware.
6. Extends life of older applications
If you are dependent upon older applications that don’t run on the latest operating systems or hardware, you can continue to run these in a virtual machine. This allows you to keep the rest of your IT environment up-to-date, while reducing your dependence on older, unreliable hardware.
7. Helps to get new servers up and running faster
New servers can be up and running in minutes by using server templates that can be easily cloned.
8. Reduces energy consumption
Using fewer physical servers means significantly less electricity consumption. And, as servers produce a lot of heat, your cooling costs will be lower too.
