Contributing to the Radius control-plane

July 2, 2026 ยท View on GitHub

The Radius control-plane services are the microservices that run to deploy and manage applications and cloud resources. This page is an index of relevant topics for developing with the control-plane.

If you need code-oriented architecture context before changing the services, see the architecture docs in ../../../architecture/README.md. The most relevant pages are the service interaction map, shared runtime, UCP, dynamic-rp, controller, and CLI architecture docs.

For new authoring work in this repo, prefer Radius resource types and generic provider behavior in dynamic-rp over legacy Applications.* resource work.

You might hear these components referred to as:

  • UCP (Universal control plane): Front-door proxy and integration with cloud resources
  • Dynamic RP: Main authoring surface for Radius resource types and generic resource behavior
  • Legacy Applications.* RPs: Older provider processes that still exist in the runtime but are not the preferred target for new authoring work
