I believe that Software as a Service (SaaS) is the future of the ever expanding software industry. The Software as a Service (SaaS) model differs fundamentally from traditional enterprise application delivery. To successfully provide SaaS to end users, software companies must evaluate nearly every facet of their business: pricing, billing, sales compensation, revenue recognition, code, infrastructure, end user support, and more.
The end users are demanding it and competitors are already providing it, but how do software companies overcome the model, code, and operational issues preventing them from bringing SaaS to market?
One succesfull example is IBM. IBM's Software as Services Showcase provides an online directory that allows customers to search for IBM Business Partner solutions that are available to them as a service. The Showcase includes solutions that span a range of industries, such as retail and insurance, and solution areas, such as compliance and human resources.
