In the IT sector, on-demand service generally refers to cloud computing services which allows the user to access cloud resources as and when required.

It allows end users to use cloud computing, storage, software and other resources instantly and in many cases without limits. This addition of resources is generally performed in live environments through a transition process that doesn’t affect current operations.

Cloud computing ensures an easy provision, access, integration and deployment of mission critical applications by providing almost all the core components of an enterprise IT architecture. Signing up for this service is an absolute easy task as well.

Cloud computing not only provides an easy access to resources, it also provides flexibility in scaling these resources up and down according to business dynamics. Companies can access additional resources quickly and easily as and when they need them and then scale back to previous levels when those resources are no longer required.

All these attributes makes on-demand service extremely beneficial and essential.
