One of the fundamental benefits of using the services of public cloud providers is the flexibility and scalability they offer. Using the vast resources of a cloud vendor, a customer can increase and diminish their computing, network bandwidth, and storage capacity much more easily than with an on-premises data center. Instead of the capital expense involved in procuring more hardware that may only be needed for a short time, organizations can scale up to address seasonal or unexpected demand spikes. When the demand on their systems returns to normal levels, they can scale back down to avoid paying for unnecessary capacity.
