How does a reliable and fast continuous delivery contribute to Engineering Culture? And how does Pipedrive do more than 65 production deployments per day? Answers are in this presentation. I just warn you, without my energetic speech, it's only half of the fun :)

1. Continuous delivery
How do we do 65+ production
deployments per day and what is the
impact on Engineering culture?

Tech stack run-down
Most of our micro-services code
React.js
Most of our front-end code
PHP
Legacy remains of a monolith beast
we cannot get rid of completely

7. Infrastructure tools run-down
Github
All code goes here. 715
repos.
Jenkins
Automator of deploys
Codeship
Code analytics and tests
Docker
Containers, containers
everywhere
Rakett
Internal tool. Orchestrator of
deployments
Openstack
Our cloud platform

15. Key elements to continuous delivery
It cannot work without them

16. Version control over your code1
Automated tests2
Automated monitoring5
Automated deployment to all environments4
Automated builds3
Minimal requirements for continuous delivery
10-15minutes
Scalable architecture6
Enables

17. Architecture enabling fast deploys

18. Continuous delivery step-by-step

19. Features of code versioning tool
Standardized flow
Agree as a team/company on one approach
and follow it
Pull requests
Do code reviews early and configure your
gates automatically
Inline CI feedback
See the status of all configured checks inside
your CVT
One-click deployment
Ability deploy to testbox or production with
one click
Inline CD feedback
See all the information about ongoing
deployment from your CVT
Auto-cleanup
Set up your CVT to automatically delete
deployed branches

20. Unified process - Simplified Git flow

21. Continuous and fast feedback

22. Trigger CD from pull request
Inline CD feedback

23. Integration with Slack

24. For when things go wrong

28. Continuous deployment → Continuous delivery

29. Not-so-continuous delivery fuckups
And similar fairytales

30. Continuous delivery fuckups
No code versioning, nothing
A lot of production bugs, no code reviews →
random code quality
Too many flaky tests
When 80% becomes the new 100%
Waaay too many flaky tests
When running a full test suite takes 36 hours
on a latest quad core MBP
Root access to production env
Tick-tock, tick-tock, tick-tock ...
When there’s still a QE role
… and tests become a pile of unmaintainable
spaghetti code
Add your own ...
… we want to hear it

31. Thank you.
