1. MAXIMIZING
Developer Productivity
in a
Microservices Environment
Tom Petr // @tpetr

2. Over 100 engineers
Over 1,600 deployables
~300 daily deploys
From git push to Production
in about 10 minutes

3. Engineers own the end-to-end success
of their products.
They make most tech decisions;
they wear the pagers.
We don’t have an “ops” team.

4. PaaS is all about
empowering engineers.
Give them good tools
and a solid foundation so they
can focus on what they do best.

5. Microservices allow us
to scale and move fast.

6. Maps well to our teams.
Minimizes merge conflicts.
Compartmentalizes failures.

7. ✨ Everyone works on their own thing! ✨

8. AWS
Java
HTTP + JSON

9. Reliable Message
Delivery

10. Make HTTP easy

11. Decouple code and
configuration

12. @Inject
@Named(“my.config.value”)
private Value<String> myConfigValue;
myConfigValue.get();

13. Monitor everything!

16. Decouple build process
from build system

17. Decouple frontend
from backend

18. Automate deployments
and infrastructure

19. Before:
1. Develop locally
2. Provision QA hardware
3. Deploy via local Python script
4. Provision PROD hardware
5. Deploy via local Python script
…
6. Replace hardware at 4am

20. After:
1. Develop locally
2. Deploy to QA
3. Test
4. Deploy to PROD
5. 🎉

26. Worry about some
optimizations later

27. Invest in
onboarding early

29. Things will fall
through the cracks

this all from scratch!
