You might very well think this is a strange title for a blog – after all, they seem like two completely different things. It’s like saying apples versus mountain bikes! |

However, think about it a little deeper. Both of them are trends in computing and both would take IT departments in totally different directions. At some stage, managers are going to have sit down and decide which route they are going to take.
Let me explain my thinking in more detail.
On Demand computing describes a method of making computing resources available to users at the time those resources are needed. Basically what happens is this: users have lots of computer capacity available at their site, but pay only for the capacity they use. That way they are not paying to support peak capacity during quieter periods. They use as much capacity as they require at any one time and that’s all they pay for. They don’t pay for the extra capacity on the occasions when it isn’t needed, only when it is needed and used. On Demand computing has been tipped by many to be the next big trend in computing. After all, it makes sense for a company to have all the capacity it will ever need, but only pay for the capacity it is actually using. |
