2. Bonjour!!

3. France <-> Japan

4. Michael H. Oshita (@ijin) • Cloud Engineer/ Architect • From

   Japan • AWS community • Serverless community • https://ijin.github.io

5. JAWS-UG • ~2300 members (FB) • 50+ subdivisions nationwide

6. Serverless Community • 600+ members (FB) • Monthly Serverless meetups

   • ServerlessConf Tokyo 2016 (380), 2017 (462 attendees)

7. Story… One example of using serverless to help and accelerate

   DevOps

8. AGENDA • Background • Issues/Demands • Solution • Architecture •

   Demo

9. Background (simplified)

10. Issues • Resource (CPU, memory) bound • Maintenance (disk usage,

    server failures) • Updates (ruby, jenkins, docker version) • Sequential execution • More projects, more load

11. New demands • Faster (concurrent) deployments • Test and deploy

    multiple versions • On-demand environments • ECS

12. Solution: Automate

13. Branch A

14. Branch B

15. Branch C

16. Create env • Create target group • Create ALB listener

    • Create ECS service • Deploy if necessary

17. Create env (reality) • Create target group • Create ALB

    listener • Create ECS service…….wait • Deploy if necessary

18. Destroy env • Stop tasks • Delete service • Delete

    listener • Delete target group

19. Destroy env (reality) • Stop tasks…wait…wait…. • Delete service…..wait •

    Delete listener • Delete target group

20. Create env w/ step fns

21. Destroy env w/ step fns

22. Step Functions Serverless Step Functions plugin by @horike37 https://github.com/horike37/serverless-step-functions sls

    plugin install -n serverless-step-functions

23. Step Functions JSON =( Not something a human should touch

24. Step Functions YAML =) Somewhat better… ..

25. [ Demo ]

26. Create env (youtube: http://bit.ly/ecs-deity1)

27. Destroy env (youtube: http://bit.ly/ecs-deity2)

28. On-Demand env!! • Devs Happy :D • Ops Happy :D

29. Why Serverless (Framework)? • Concurrency • Scalability • Less maintenance,

    more coding • Easy deployments (w/ frameworks)

30. Afterthoughts • Overall satisfied • Scales pretty well • Visualization

    is awesome • Complex Obervability (Logs spread across streams)
