NYC Continuous Delivery Meetup - Introducing delta
- 1. Continuous Deliveryw/ Travis,Github, Docker, and AWS Michael Bryzek mike@flow.io / @mbryzek Cofounder / CTO Cofounder / ex-CTO Gilt Groupe NYC Continuous Delivery Meetup June 1 2016
- 2. FlowCommerce Flow is a next-generation solution for taking merchants global - more at https://flow.io We are about to launch and are hiring – email mike@flow.io if interested
- 3. Why this Talk Many of our friends in the community saw a glimpse and asked if we could share more Paolo presented this year at PG Conf NYC on psql work – and lots of people expressed interest in CD We are thrilled to introduce delta today
- 4. as of tonight, delta is open source and still earlyenough to contribute github.com/flowcommerce/delta
- 5. Key Insight CD systems shouldfocus on audit and transparency Not an opinionated way to do things
- 6. Deploys at Flow aretriggered automatically by newtags Newtags arecreatedautomatically By MergingPullRequests
- 7. Livedemo
- 8. Delta Architecture UI: playframework/scala webapp that speaks only to API REST API in playframework/scala + akka - http://apidoc.me/flow/delta Postgresql
- 9. Key stages of Continuous Delivery
- 10. Stage 1:Sync Shas For each repository, keep a list of all of the unique shas
- 11. Stage 2:Synctags For each repository, keep a list of all of the unique tags
- 12. Stage 3:tag Automatically apply a new tag whenever the latest tag does not point to HEAD For delta, we assume semantic versioning (x.y.z), and each auto applied tag increments the micro version
- 13. Stage 4:Set Desired State Declare which tag should be in production
- 14. Stage 5:Builddocker image Automatically build docker images for every tag in desired state
- 15. Stage 6:scale Once docker image is ready: Create new cluster running new version Once healthy, move traffic Scale down old version
- 17. Delta Event Log Continuous delivery
- 19. Usageat Flow select avg(count), stddev(count) from (select date_trunc('week', journal_timestamp), count(*) from journal.build_desired_states group by 1) m; Releases: >1500 Weekly: > 100 Team size: 5 Thank you to: github.com/gilt/db-journaling
- 20. Delta Roadmap Deploy branches other than master Dependency support within a repo Smarter traffic management Better healthchecks More settings (enable/disable build in UI) UI / UX Improvements Contributors welcome and encouraged!
- 21. What aboutContinuousIntegration? We use travis-ci, and merge pull requests when all automated tests pass
- 22. OCD UpdateFridays Micro service architectures need to be constantly maintained Every Friday, we update all projects to latest versions of every library Enabled by another Flow open source project: github.com/flowcommerce/dependency
- 23. “Delta deploys itselfwhile deploying almost all of our applications onOCD Update Days at Flow”
- 24. Continuous Delivery Has Become a BasicNeed

- 27. DecouplingDeployment fromRelease “We recommend strictly using the term Deployment when referring to the act of deploying a change to application components or infrastructure. The term Release should be used when a feature change is released to end users, with a business impact.” https://www.thoughtworks.com/radar/techniques
