Server Virtualisation - Why Bother?

There are many reasons why 98% of the fortune 1000 businesses have deployed Vmware for server virtualisation. It is the product we will seee more of in businesses and will even one day make it to the consumer market.

Without doubt, the main reason I see virtualisation working for my customers is for business continuity. Disaster recovery is something all IT managers think about but not too many actually implement even the minimum requirements. So with the obvious benefits of server consolidation, long term lower cost of ownership through resource optimisation virtualisation provides a great platform for disaster recovery.

It is all due to encapsulation. This means the virtual servers sitting on your hardware can be encapsulated as a snapshot. These snapshots are essentially a file containing the state of your server at the time of the snapshot. If your server fails you need only “copy" and “paste" your server from the most recent snapshot and simply press “go".

This is particularly helpful as all the undocumented server changes that happen over the months or even years within an organisation are kept. You can be sure the server will run EXACTLY like it was before any downtime. Plus you can run the server on any hardware platform as long as there are enough resources and the server has a hypervisor layer installed (20 Mins on a new box). No drivers, No downloads, No hassle.

Virtualisation is not the future, it is here now. If you have even only one server now virtualisation can provide you with an affordable DRP solution.
