I thought this was over. I thought the industry had learned its lesson – installing vertically monolithic tiers from a single vendor that uses "standards" as a marketing term and not a core business principle does not a) reduce cost, b) put you in a leveraging position with that vendor, c) improve user experience, or d) reduce complexity. I guess we haven't learned our lesson – Software's "stack wars".
Actually, I think this is a fluff piece meant to try and revive the thinking of this architectural style amongst the dinosaurs that still desperately cling to these notions. The first commenter points out the obvious.
