I was reading an article recently which talks about the cloud computing having limitless power. I find it quite interesting that it mentioned limitless power because the cloud has nothing to do with limitless power. Cloud, like Web x.x, is just a mesh of technologies that were combined together with a jazzy word. Cloud just makes it easier to provision for services.
However Cloud computing like any other hardware, does not have limitless power. What Cloud can do is to attempt to fully utilise the existing computing power in the Cloud, especially using the thin provisioning concept. It is able to adjust the processing power of the applications within the cloud, provided it has enough reserves in place.
The cloud concept is largely use nowadays to increase the utilisation rate of the existing hardware, thereby resulting in savings. Therefore, it is quite unlikely that there are sufficient reserves in place to provide limitless power. More likely than not, the reserves are used in the event of any hardware failure so that the services can still be provided, albeit a bit slower until the faulty components can be replaced.
Not sure where did the writer got the idea of limitless power. That's not cloud.
