The answer is called Helm. <a href="https://github.com/kubernetes/helm" rel="nofollow">https://github.com/kubernetes/helm</a><p>PS: ? and " are on the wrong order in the headline.
Ok, so, the only difference between packaged and managed is that the first one doesn't have an additional piece of software that manages running software in a distributed environment, kind of like ops. If we isolate that piece of software and try to come up with an architecture that provides flexibility to manage absolutely anything - we get supervision trees. Combining that idea with nix-like package management should bring us towards self-healing self-managing services the article has in mind. However, it will not be a package manager for the cloud, but a package manager for arbitrary servers in datacenters that replaces the cloud.
I hope NixOps will be in that list in future: <a href="https://nixos.org/nixops/" rel="nofollow">https://nixos.org/nixops/</a>
