What is cloud computing and what does it mean for me?
August 12, 2012 Leave a comment
Cloud computing has been around for years… It just never got called that before. If you have ever had a Hotmail or Gmail account, or even just downloaded your email from your web site host, you have already used the “cloud”.
Actually the true definition of cloud computing is pretty deep but, as usual, marketing hawks the world over have managed to twist it to mean a whole host of things (forgive the pun).
The cloud is what you use when the applications you use don’t actually live on your computers. More often than not, you rent these applications.
What’s an application? Well that’s the software you use to achieve a particular function. It may be a simple mail system such as Hotmail or a sophisticated enterprise management system such as Netsuite.
It could be your web site customer interface that allows your customers to purchase from you. None of these things need to be purchased any more. The relatively recent quantum increases in Internet connection speeds mean that it doesn’t really matter where your applications live.
That’s the simple definition. It gets more complicated. If you can stand it…read on.
Cloud and virtualization go hand in hand. If you are not sure what virtualisation is, have a look at this.
It used to be that virtualisation used to be just about getting a server or a workstation to run “virtually” on a host computer. Then companies such as VMWare and Citrix really started to get very tricky. How about being able to virtualize just a part of the computer? What if you could get all the bits of software that will run Microsoft Excel, for example, and package that all up to run as a virtual “package”? And if you could do that, could you serve it to more than one person remotely? And if you could do that, could you do that for hundreds? Thousands? If it were to be thousands, would you need to distribute the serving of this application package over more than one server? Would they need to be in the same room? What if you could dial up these servers as you needed them?
Well, if you can answer yes to all of these questions…what would you call that technology?
It’s called the cloud folks, and Microsoft, VMWare, Citrix and others are all delivering this right now. At the moment, the pricing puts this in the reach of medium to large organizations, but the costs are dropping daily. And the cloud capacity builds, larger companies are looking to offset their costs by offering discounts to their smaller counterparts.
Cloud is here to stay….think about that before you purchase your next server….do you really need it?
