Oracle Integration Cloud is typically classified as a Platform as a Service (PaaS). It provides a comprehensive suite of tools for integrating various systems and automating processes, serving as a platform on which you can develop, manage, and run applications.

While it includes components that could be considered Software as a Service (SaaS) in the sense that they are software applications delivered over the web, the overall offering is more aligned with PaaS, as it provides a platform for developers to build upon rather than a finished software product designed for end-users.
