What is Cloud Computing?

by Manx Telecom's Hosting and Solutions Manager, Stephen Trimble

Ask 10 different people, and you’ll probably get 10 different answers! All of their answers though should have the same essence - “the cloud” is turning IT into a commodity.How Cloud Computing works

We all use electricity – it’s there whenever we turn things on and when we need more of it, we use more - a commodity. However, we don’t all need our own power station, sub station or generators – we pay for what we consume, when we need it. Similarly, with Cloud Computing you don’t need to buy computers, software, a Data Centre etc – you pay for what you need, when you need it – from the cloud, as a service.

Another good analogy is car rental - where anyone can hire a car, you pay for how much you use, you can give it back and stop paying, and more cars are available on demand whenever you need them. Compare this to buying or leasing a car where you have to also sort out road tax, licensing, servicing, maintenance. With car rental (and cloud computing) the hardware worries are taken away – you pay for the service.

For the past 2 years Manx Telecom has been heavily utilising Cloud Computing technology to provide cost effective, flexible and scalable infrastructure solutions to our Managed Hosting clients at our Douglas North Data Centre.

Data Centre

In the Data Centre arena customers need access to high-availability computing power which can scale quickly and deliver the performance needed for their applications.  We have moved from a rather conventional tin-shifting approach to a far more flexible model – this has resulted in significant wins with over 300 high-availability virtual servers being managed - spread over multiple geographic locations giving the highest availability possible. 

Our new Business Continuity Centre also utilises cloud technology, right out to the end-user terminals. All of the 118 terminals can be used for a multitude of different functions, served from the “cloud” (on this occasion based at our Douglas North Data Centre), without any change in their configuration. They can be used just as end-user PC’s one minute, then power cycled and used as a training room within a couple of minutes.

Cloud Computing is about taking away the constraints of scale – not caring where the resources come from (the cloud), but just requiring them to be there, when you want them.
