There's OpenStack. It's a private IaaS. Had loadbalancers, ipv6 support, support for K8s hosting via the magnum component (and other container orchestrators), HA via Masakari component. The networking is very flexible. It does not currently have functions as a service, I believe that was in the Senlin component, but that's been abandoned, I believe a new incarnation of the idea is in the works though. With something like Kolla-ansible a containerized OpenStack infrastructure is pretty damn easy to manage, upgrades are just making sure you make any needded changes in the global config file (just a vimdiff with the new sample one included in the release) and then literally just a kolla-ansible upgrade -i inventory-file.yml.

I'm just a home labber and I've run OpenStack via kolla-ansible for like 7 years now, and Ceph since the jewel release I think almost 8 years ago for storage. Both are pretty easy to manage.
