Cloud computing is made up of three key segments: Software-as-a-Service (SaaS) offerings, Infrastructure-as-a-Service (IaaS) offerings and Platform-as-a-Service (PaaS) offerings. We forecast that the worldwide cloud market is estimated to grow 126.5 percent during the period from 2011 through 2014, driven by 119 percent growth in SaaS and 122 percent growth in IaaS. The PaaS segment is expected to nearly triple from a smaller base.
Though some still have reservations about moving to the cloud, curiosity about cloud computing and its benefits have taken hold of the enterprise community. This report forecasts a shift over time to a hybrid cloud, though all areas of the sector will continue to grow immensely over the next two years.
