The admin guide has two pages showing the conceptual[1] and the logical[2] architecture of OpenStack. I don't understand the difference between the two; the diagrams on the two pages both show the core services; the difference is that the "logical" diagram is much more detailed. Can anybody provide insight what this distinction "logical/conceptual" is supposed to mean? I am asking because I plan to rewrite the text on the "logical" page.
