Comment 10 for bug 1645339

I support a move to both containers and kubernetes, but your terms are more than just semantically wrong.

Traditional cluster technologies can be containerised, can manage containerised services, can run on more or less than 3 nodes, and don't require a homogenous distribution of services[0]; and kubernetes based approaches rely on shared storage *cough* database *cough* neutron *cough*.

In any case, we should document the "traditional reliable HA" architecture that works today, rather than the "optimistic HA" (terms don't matter right?) ones that are still evolving[1].

[0] Whether they should, or are the best tool for the job is a different question.
