By paying only for what you actually use, you can reduce the operating costs involved. Extra resources may be purchased at any time and then relinquished once peak loads have subsided.

For this to work effectively, you would host resource-intensive processing in the cloud, which can be scaled when required and back down again after the results of the processing are returned to the on-premises application.

On-premises infrastructure resources can be made redundant or freed up by moving systems into the cloud, thus reducing licensing costs.

Most cloud infrastructures provide the capability to dynamically scale resources up horizontally and vertically as demand increases or down as demand tapers...
