Cloud Computing 101: George De Bono debunks some myths
This month Kipp is doing a special report on Cloud Computing. To start things off, we spoke to George DeBono, Red Hat’s general manager for the Middle East and Africa, to discuss what you need to know about whether Cloud Computing is right for your business.

What is cloud computing?
That is a question I get a lot. The reality is, cloud computing is nothing more than a different way to deliver data to the masses; the masses being a public forum or an internal organisation forum. People have this concept that cloud is the ultimate answer, but it is not. It is just one of the many answers. Again, it is just a delivery platform it is a natural evolution in terms of the way data gets presented to people. It is something that is not 2011, it is not new. It is something that has been around in thought and in concept and in evolutionary phase for quite some time. Cloud was first referred to by one of the guys in an IBM lab in the early 60’s. An old dog like me who has been in the business since the ’80’s, first time I saw somebody draw a cloud in an architecture diagram it was 1989, so it is not new, it is just evolving.
How would you define the ‘Private Cloud’?
Private cloud is a cloud infrastructure that is contained within an organization. To be used the data or the results or output or whatever you want to call it to the constituents of the business. And even within a private cloud you have two private clouds: a cloud that is dedicated to one specific department within an organisation, rather than being for an entire organisation.
And the ‘Public Cloud’?
Public Cloud? Amazon. Yahoo. It is IBM. It is where a cloud solution is being offered on a pay per use type model by a thrid party provider which for organizations who want to test/try cloud it is not a bad thing, but it has risks, it has limitations.
What are the risks associated with cloud computing, in particular public clouds?
You are not in control of the infrastructure, you are not in control of the security mechanisms. You are not in control of your data because your data resides outside of your environment and that is the key issue. The other big issue that we have with public clouds is vendor locking. You need to have the flexibility with respects to the public cloud infrastructure to be able to at some point in time take back your data.
And finally what are ‘Hybrid Clouds’?
So hybrid is a combination of the first two. Let’s say a company thought cloud was a good idea but didn’t want to invest a lot. They wanted to see what could be done so they entered an arrangement with a public cloud provider. Around the edges of that, when they have verified that the cloud could deliver something good for them, they started to build their own structure using their own cloud, which was used for end-of-month or end-of-the-year processing type stuff. Often times, this is when they’ll realise that was really the wrong thing to do. What they needed to do is go the other way around—to have their own cloud infrastructure servicing normal work load and then whenever they were approaching the peak and needed incremental work load for short periods of time then they could license that in the public cloud provider.
Ideally for hybrid clouds, companies should have their own cloud infrastructure that run day-to-day and then when they need the extra processing, this is the time when they should go out and add more cloud from their cloud provider.
