Oracle Integration Cloud (OIC) is a cloud offering from Oracle designed to integrate various applications, automate business processes, and perform other related functions. It can be categorized as Platform as a Service (PaaS) because it provides a platform that allows developers and enterprises to build, deploy, and manage integrations between various services without having to manage the underlying infrastructure.

While it does provide software capabilities, it is not a traditional Software as a Service (SaaS) solution, which typically refers to end-user applications delivered over the web. Instead, OIC provides the tools and platform for integration, which fits the PaaS definition more closely.
