The article makes a lot of good points, but the stack you're speaking of would be pretty trivial to get going...particular if you did it on a single host setup. You could probably have it spun up in an afternoon with Ansible or some such.

Multi-Host is moderately more difficult. A full orchestration and resource scheduling stack that scales with load even more so.

But you have to ask what your needs are if you're being realistic.
