The document discusses Software as a Service (SaaS) and its benefits over traditional on-premise software. SaaS provides software applications as an online service that users can access through a web browser. Key benefits include lower upfront costs, easier implementation and maintenance, continuous updates, and disaster recovery built-in. While SaaS gives users less control over systems, it offers a predictable subscription-based pricing model and shifts responsibility for software and infrastructure to the provider. The document explores why IT professionals should consider adopting the SaaS model.
