Another major business benefit of Cloud is efficient Resource Utilization:
System Administrators usually worry about hardware procuring (when they run out of capacity) and better Infrastructure Utilization (when they have excess and idle capacity).
With Cloud Architectures they can manage resources more effectively and efficiently by having the applications request and relinquish resources only what they need and when they need. This is called on-demand, which is a primary characteristic of a Cloud Infrastructure.
