Cloud computing

Cloud computing is the on-demand delivery of compute power, database storage, applications, and other IT resources through a cloud services platform through the internet with pay-as-you-go pricing. 

Cloud Computing is a model for enabling omnipresent, convenient, on-demand network access to a shared pool of configurable computing resources (e.g., networks, servers, storage, applications, and services) that can be rapidly provisioned and released with minimal management effort or service provider interaction.
