Canonical has two really good projects - MAAS and Juju. Which allows one to build out Openstack and Kubernetes clusters fast and easy [relatively speaking]. They of course favor "Ubuntu", but also include Centos support and/or references in their documentation. My question is, has Oracle reached out to Canonical to become the 'replacement' for Centos going forward? Has Oracle considered working with Canonical on these projects?
Another project to consider would be Suse and it's Uyuni (uyuni-project.org). Seems like the are furthering along with a long term replacement to spacewalk than Oracle Linux Manager is. Salt stack inclusion is also very nice.
