Cloud computing saas
This document discusses Software as a Service (SaaS) and related cloud computing models. It begins by defining SaaS as software delivered via subscription and hosted centrally. Key advantages of SaaS include lower costs, faster deployment, scalability, and vendor responsibility for upgrades. The document compares SaaS to older Application Service Provider (ASP) models and contrasts SaaS with Service-Oriented Architecture (SOA) and utility computing. It also discusses single-tenant versus multi-tenant architectures and provides an example SaaS solution delivery process.
