I run a private hosting company for high speed WordPress sites + use this approach.

1) At machine level run a common version of Ubuntu (Zesty right now, as Artful changes to netplan) + LXD.

2) Each LXD container may contain a single site or several/many sites.

3) One machine only runs an LXD DNS instance (container) + many low traffic dev sites, so if this machine goes down, not big problems.

4) I apply all machine updates to dev machine + if all goes well, stream machine updates to other machines. I use custom tools + likely I'll change over to using http://manpages.ubuntu.com/manpages/artful/man1/parallel.1.html shortly.

5) Then I go through the same process on a container basis. Update one container running a full LAMP Stack + if all goes well, stream updates to all containers.

6) For machine level, full OS updates, I take a slightly different approach.

I migrate all dev containers to another machine.

Then do a fresh install on my dev machine, then move one live machine's containers to the dev site + to a fresh install on this machine + move all containers back. The repeat this for all machines.

I do fresh installs, rather than updates, as updates can occasionally Brick a machine. Taking this approach means I never have to worry about an OS upgrade taking down production sites.
