What is SaaS (Software as a Service)?

A cloud delivery model where software applications are hosted and managed by a provider and accessed by users over the internet.

SaaS is the most common cloud service model where complete applications are delivered over the internet on a subscription basis. Users access software through web browsers without installing or maintaining anything locally. Examples include Gmail, Slack, Salesforce, Dropbox, and Microsoft 365. The provider manages everything: infrastructure, platform, application code, updates, security, and availability. SaaS offers the lowest operational burden but also the least customization flexibility.
