We all hear about Conway’s law, but this fact is the strongest reason why you’re not going to do micro services. People win. Culture wins. Paper processes and paper structure does not win. If you have a UI team, DB team, "services" team, each specializing in its own right, you’ll end up with systems that look like those tiers.
La culture est le reflet des personnes composant une équipe, pas des technologies ou des outils employés. Le turn-over technologique est le reflet d’un souhait profond de changement à une plus large échelle.
