Cloud computing is the name given to an IT concept that goes far beyond the usage of computing power per se. Essentially it's about outsourcing IT services to external service providers. This may include computing power and storage capacity (Infrastructure-as-a-Service, IaaS) as well as the provision of platforms with value-added services such as security solutions and billing services or the use of Software-as-a-Service (SaaS) in its many varied forms.
