Canonical offers several partner programs for Ubuntu, including a software partner program, app developer program, and a cloud software partner program, which is broken into two pieces: the OpenStack Interoperability Lab and the Charm Partner Program.
OpenStack Interoperability Lab (OIL) is for interoperability testing for OpenStack and Ubuntu. OIL offers significant benefits for partners looking to QA their products quickly and cost-effectively, ensuring they are are compatible with all versions of Ubuntu OpenStack.
Charm Partner Program
The cloud orchestrator, Juju, uses charms to demo software, integrate it and scale it up and down at the click of button. With Juju charms, any customer can deploy, integrate and scale products the same way engineers would.
