Over the course of the next five years, Gartner believe enterprises will spend $112 billion cumulatively software as a service (SaaS), platform as a service (PaaS) and infrastructure as a service (IaaS) [Gartner11]. Among the reasons given was a desire to reduce the Total Cost of Ownership (TCO) for products and services.
