5. In short, the microservice architectural style is an approach
   to developing a single application as a suite of small
   services, each running in its own process and
   communicating with lightweight mechanisms, often an
   HTTP resource API.
   — James Lewis and Martin Fowler

6. Our main aim in writing this article is to explain the major
   ideas and principles of microservices. … We have recently
   built several systems using the style and know of others
   who have used and favor this approach.
   Those we know about who are in some way pioneering the
   architectural style include Amazon, Netflix, The Guardian,
   the UK Government Digital Service, realestate.com.au,
   Forward and comparethemarket.com.
   — James Lewis and Martin Fowler

29. I am sorry to disappoint my fellow techies, but the
    reason we migrated to microservices had to do much
    more with productivity than pure technical matters.
