What is SaaS (Software-as-a-Service)?

Software-as-a-Service (SaaS) is a software distribution model where applications are hosted in the cloud and accessed by subscribers over web browsers.

Detailed Explanation

SaaS platforms eliminate client-side installation friction. Modern SaaS engineering requires robust multi-tenant database isolation (Row-Level Security), subscription billing integrations (Stripe/Paddle), and global CDN distribution.
