SaaS
SaaS (Software as a Service) is a cloud computing model where software applications are hosted and managed by a third-party provider and delivered over the internet on a subscription basis. It eliminates the need for users to install, maintain, or update software locally, as everything runs on the provider's servers. This model is widely used for business applications like CRM, email, collaboration tools, and enterprise software.
Developers should learn SaaS to build scalable, multi-tenant applications that can serve many customers from a single codebase, reducing operational overhead and enabling rapid deployment. It's essential for creating modern web-based services, integrating with APIs, and understanding cloud economics, as SaaS dominates markets like CRM (e.g., Salesforce), productivity (e.g., Google Workspace), and development tools (e.g., GitHub).
