The document discusses the rise of cloud computing and software-as-a-service (SaaS) models. It notes that SaaS is becoming mainstream due to economic pressures, changing customer expectations, and enabling technologies. SaaS provides benefits like lower costs, faster deployment, and continuous updates over traditional on-premise software. While early attempts at outsourcing software failed, the cloud and SaaS approach is gaining adoption due to advantages like multi-tenancy, analytics, and communities of users. The cloud market is large and growing rapidly across applications, platforms, and infrastructure services.
