From the report:
Cloud computing is rapidly growing. According to a Forbes article by Louis Columbus, the cloud spending growth rate is expected to stay in double-digits through 2016. However, much of this growth is based on only one of three service models as defined by the National Institute of Standards and Technology (NIST): infrastructure as a service (IaaS).
IaaS provides basic data center infrastructure. Upon this foundation, an organization (the customer) can provide its own platform and applications services. It can also choose to rely on the cloud services provider for additional functionality: platform as a service (PaaS) and software as a service (SaaS). With PaaS, the provider installs operating systems, database services, and other platform and network services supporting business applications. It builds on IaaS.
SaaS, the focus of this report, builds on PaaS, providing business application components or entire core business solutions. Some providers offer only one or two of these services. Others might offer more.
In February 2013, TechRepublic conducted an informal online survey to test the current reach of SaaS and characteristics customers look for when making a decision to move services from their own data centers to the cloud. This analysis examines the results from 359 respondents and puts them into the overall context of business management, cloud capabilities, and potential gaps.
