Upon further investigation, I think some reorganization of sections in the Networking service chapter (Bug #1263716) and minor restructuring of the Architecture chapter (Bug #1263719) may offer the easiest way to impart knowledge of architectures referenced in the Havana installation guide while concentrating on Icehouse for more elaborate changes including new diagrams.

Upon further investigation, I think some reorganization of sections in the Networking service chapter (Bug #1263716) and minor restructuring of the Architecture chapter (Bug #1263719) may offer the easiest way to impart knowledge of architectures referenced in the Havana installation guide while concentrating on Icehouse for more elaborate changes including new diagrams.
