Software as a Service (SaaS) (A) delivers fully managed applications (e.g., Gmail, Salesforce). Data as a Service (DaaS) (C) provides data on demand, typically via APIs. Platform as a Service (PaaS) (D) provides a managed platform for developing and deploying applications without managing the underlying infrastructure.
