What is SaaS (Software as a Service)?
SaaS (Software as a Service) is defined as a cloud-based software licensing model where applications are hosted by a provider and accessed by users over the internet, typically via subscription.
Detailed Architectural Context
Software as a Service (SaaS) enables businesses to deliver applications without requiring local installations. Modern SaaS products are built on cloud infrastructures (like AWS) and employ multi-tenant databases. Key features of standard SaaS configurations include tiered subscription billing (typically integrated with Stripe), self-service customer portals, role-based user authentication, and high-availability operational structures.
