The main distinction between SaaS (Software as a Service) and PaaS (Platform as a Service) lies in the level of service provided. SaaS delivers completed software applications over the internet, enabling users to access and use them without needing to manage the underlying infrastructure. PaaS, on the other hand, provides a platform that enables developers to build, test, and deploy their applications while handling the underlying infrastructure. This distinction primarily concerns the target audience—end users for SaaS and developers for PaaS.
