With Entanglement Garden we have taken the approach of creating system
images for each service. We use Packer for building the images,
which allows us to define the configuration and build steps easily, and
keep that in revision control. You can see some of these repos here:
Back to DebOps, and Ansible in general: We use it. We don’t hate it…

when we really need dynamic configuration. We prefer to setup things as
immutably as possible, so we try to lean on “Packer” to relieve our use
of Ansible as much as possible.
Of course, running each service in a virtual machine will incur more
overhead than the processes running on a shared host, but I don’t see a
good solution for doing that in a shared-hosting environment barring
