Oracle Cloud Infrastructure (OCI) is Oracle's cloud infrastructure platform for compute, storage, networking, databases, security, application hosting, and enterprise workloads. It is commonly used for Oracle-centered enterprise environments as well as general infrastructure, platform, and cloud operations needs.

OCI belongs under Cloud Computing & Virtualization because it represents cloud infrastructure services and enterprise cloud operations rather than an individual SaaS application.
