Definition
SaaS (Software as a Service) is a software distribution model where applications are delivered over the internet on a subscription basis. Users do not need to install software or manage servers; everything runs in the cloud and is accessible via a web browser.
Technical Explanation
SaaS applications run on multi-tenant architectures where multiple customers share the same infrastructure while their data remains isolated. The provider manages hosting, security, updates, and scalability. Technically, SaaS frontends communicate via REST or GraphQL APIs with backend services running on cloud platforms such as AWS, Azure, or Google Cloud. Authentication uses protocols like OAuth 2.0 and SAML. Integrations with other systems are achieved through APIs and webhooks. The revenue model is typically a monthly or annual subscription with different tiers.
