What is on-demand functionality? How is it provided in cloud computing?
On demand functionality is a model which allows computing resources to be made available when they are needed. The resources are usually provided through the internet. Resources such as storage capacity, processing speed and applications or software are made available to users. These resources are highly useful for temporary short term or for long term projects, for routine work and for computing requirements. The major advantage of this is that it reduces the cost, as the resources are rented and can be made available when required.
