Configuration for smaller deployments

While I understand the goals of high availability and scalable installations, some of us really need nothing more than what the old Omnibus chart provides. Unfortunately, with that becoming deprecated, it would be very nice to have a configuration example for smaller deployments.

In my particular case, we are a non-profit that cannot afford a large infrastructure. Having a config that gives something equivalent to Gitlab-Omnibus (e.g. 2VCPU, 4GB memory) would be great. These numbers aren't critical.
