I often get calls from clients asking me if particular vendor is a true SaaS vendor or not. The problem is the answer is not that simple. Regardless of the answer clients still need to conduct technical and operational due diligence of any vendor they are considering. A quick rule of thumb is SaaS is one of three layers of cloud computing with the other two being infrastructure as a service (IaaS) and platform as a service (PaaS). SaaS enables enterprises or consumers to access application functionality as a service without having to worry about the underlying operational or infrastructure details on how the application is implemented.
The key words in the rule of thumb are cloud computing. Cloud computing regardless of the layer of stack has 5 basic attributes: Services-Based, Shared, Scalable and Elastic, Metered by Use, and Internet Technologies. SaaS applications need to leverage these attributes to some degree. How a SaaS vendor leverages these attributes will vary. I just published a refreshed the Gartner definition of SaaS that will offer an answer to whether a vendor is more or less likely to support SaaS.
