One thing I loved about Amazon was having no architects, visio, powerpoints, UML in any of the teams I worked in. Each service is designed, documented, implemented, deployed, maintained and advertised to other teams by the same few engineers. Most documentation and runbooks are just text in wikis. If your service cannot be documented without drawing 10 boxes and 20 arrows you should split it in smaller services.
