Red Hat Enterprise Linux (RHEL) is now certified to run on Oracle Cloud Infrastructure (OCI), Oracle's cloud services platform, as a supported operating system, the two companies announced recently. The move is part of a multi-stage alliance to offer customers a greater choice of operating systems to run on OCI, they said.

Red Hat, a subsidiary of IBM, is one of the world’s leading providers of open-source solutions. RHEL is a commercial open-source Linux distribution developed by the company for the commercial market.
