The discipline of modern information systems is based on service science, and within that domain, this paper seeks to analyze the underlying principles that govern the exchangeable value of software services. Software-as-a-Service (SaaS) has been defined as software deployed as a hosted service and accessed over the Internet. This paper covers the democratization and monetization of software services and uses cloud computing as the primary delivery vehicle. Cloud computing represents a contextual shift in how computers are provisioned and accessed. Opportunity and value exists in software-as-a-service for providers and clients, and the economic and technical essentials are reviewed in this paper.
