which are copies of the communication
structures of these organizations...
● Organized around Business Capabilities
● Products not Projects
○ development team takes full responsibility for the

Microservices are the unix way
This is the Unix philosophy: Write programs that
do one thing and do it well. Write programs to
work together. Write programs to handle text
streams, because that is a universal interface.
Doug McIlroy, head of the Bell Labs CSRC (Computing Sciences
Research Center), and inventor of the Unix pipe
Mike Gancarz: The UNIX Philosophy
1. Small is beautiful.
2. Make each program do one thing well.
3. Build a prototype as soon as possible.
4. Choose portability over efficiency.
5. Store data in flat text files.
6. Use software leverage to your advantage.
7. Use shell scripts to increase leverage and portability.
8. Avoid captive user interfaces.
9. Make every program a filter.
With all the frameworks out there
