The document discusses some of the pros and cons of using microservices compared to monolithic applications. Some advantages of microservices include that they are simpler to develop, allow for faster build and deployment times, enable more scalable development with empowered teams, and provide more freedom to try different technologies. Some challenges of microservices include that they have complex operations and distribution, require managing multiple databases and transactions, are harder to test as distributed systems, and require coordination when changes affect multiple services.

5. What’s the matter?

6. developers are
afraid of changing
the code

7. deploy the whole thing to
change a single component

8. it increases the risk
of failure

9. testing is slow

10. IDEs and Webservers
overloaded

11. Hard to scale development
(too much coordination needed)

12. Requires long term
comprimisses with
technologies chosen

14. What’s the gain?

15. Simpler
Development

16. Goodbye classpath hell!

17. Build and Deploy
are faster

18. Development more scalable
with more empowered
teams

19. Freedom to try
different technologies

20. More isolation
and reduced
risk of failure

21. And what are
the challenges?

22. Complex Operation
and Distribution

23. Managing Multiple
databases and transactions

24. Testing distributed
systems is hard

25. Coordination of changes that
affects multiple services

26. Good news! The community is growing fast,
new projects and patterns are coming and
everything is becoming easier and easier

28. Service Discovery and Load Balancing
