The Oracle Cloud Infrastructure (OCI) OS Management service is specifically designed to manage and automate updates and patches for the operating systems on OCI compute instances. It allows administrators to view, install, and manage software packages and apply critical patches, including kernel security updates, across individual instances or groups of instances. This centralized control simplifies the process of maintaining a secure and up-to-date fleet of servers.

A. Container Registry: This service is used for storing, sharing, and managing Docker container images. It does not manage the underlying host operating system or its kernel.

B. Data Safe: This is a unified control center for Oracle Database security. It focuses on data sensitivity, risk evaluation, and activity monitoring, not OS-level patching.

C. Artifact Registry: This service is a repository for storing and managing software development packages (e.g., Maven, npm, Python), not for applying updates to operating systems.
