- 2. About me: Chris Munns- munns@amazon.com – Business Development Manager – DevOps – NewYorker – Previously: • AWS Solutions Architect 2011-2014 • Lead of Infrastructure/DevOps @hingeapp • Formerly on operations teams @Etsy and @Meetup • Little time at a hedge fund, Xerox and others – Rochester Institute of Technology: Applied Networking and Systems Administration ’05 – Internet infrastructure geek

- 8. Monolithic vs. SOAvs. Microservices SOA Coarse- grained Microservices Fine-grained Monolithic Single Unit
- 9. Microservices: • Many verysmall components • Business logic lives inside of single service domain • Simple wire protocols(HTTP with XML/JSON) • API driven with SDKs/Clients SOA: • Fewer more sophisticated components • Business logic can live across domains • Enterprise Service Bus like layers between services • Middleware Microservices vs. SOA 9
- 10. • Two-pizza teams •Full ownership • Full accountability • Aligned incentives • “DevOps”
- 11. How do TwoPizza Teams work? We call them “Service teams” • Own the “primitives” they build: – Product planning (roadmap) – Development work – Operational/Client support work • “You build it, you run it” • Part of a larger concentrated org (Amazon.com, AWS, Prime, etc) 11

- 15. What about Ops/QA/Etc? Everyoneexists on a “service team” focused on their primitive(s): • SDE’s focused on developing • PM’s focused on product direction • TPM’s help drive development • SE’s focused on infra/tooling • SDET’s focused on test excellence throughout the organization Some folks are shared across the org, some on individual teams 15 Most ”2 pizza” teams are just these 2 roles
- 16. Boy, that soundslike a lot of freedom? It is! Teams are empowered and also held to high standards: • Thorough onboarding/training • Patterns/practices defined at scale and with 20+ years of organizational knowledge • Regular technical and business metric reviews • Regular sharing of new tools, services, technologies, etc, by internal subject matter experts • Public sharing of COEs;“Correction of Errors” our post-mortem process/tool 16

- 18. • Self-service • Technology- agnostic •Encourage best practices • Single-purpose services
- 19. • Deployment service • Nodowntime deployments • Health checking • Versioned artifacts and rollbacks
- 20. Things went much betterunder this model and teams were developing features faster than ever, but we felt that we could still improve.

- 28. This has continuedto work out really well: • Every year at Amazon, we perform a survey of all our software developers.The 2014 results found only one development tool/service could be correlated statistically with happier developers: • Our pipelines service! continuous delivery == happier developers!

- 33. What is DevOps? Cultural Philosophy Practices Tools •Tearing down barriers • Between teams • Mid-process • Enable the smart people you are spending time and money hiring to make smart decisions • Assigning ownership, accountability, responsibility to the people doing the work, aka “you build it, you run it” • Reducing responsibility to the most directly involved individuals • Increase visibility to the big picture and the results of work being done
- 34. What is DevOps? Cultural Philosophy Practices Tools •Continuous Integration • Application testing/QA work applied throughout the development • Continuous Delivery • Automated deployment capabilities of code across environments • Infrastructure as Code • No hand carved infrastructure • Self-service environments • Remove procurement blockers for basic needs • Microservices • Break down complicated monolithic applications in to smaller ones
- 35. What is DevOps? Cultural Philosophy Practices Tools •Automated development pipeline tooling • Application testing frameworks • Code review/feedback tools • Automated static analysis • Consistent and predictable application management & configuration management tools • Consistent infrastructure measurement tools • Metrics • Logging • Monitoring • APM • Security analysis and management tools

- 38. DevOps – Don’tTake It Just From Us: • Oscar Health: 2 systems engineers, 45+ Developers, self service infrastructure tools, HIPAA requirements • AirBNB: 5 Operations people for 1000+ instances • Gilt: several hundred microservices, self service tools extending AWS, almost entirely on t2 instances • Intuit/TurboTax:“deployed over 40 simultaneous experiments during the peak filing season” • MLB: scale up massively during Minor League games and events, turn it off later
- 39. DevOps – Don’tTake It Just From Us: • Capital One’s moved from traditional waterfall to DevOps: • 100s of code commits per day, • Integration from once a month to every 15 minutes • QA from once per month to 4 times per day • Deployment from manual to completely automated • Production release from monthly/quarterly to once per sprint

- 41. 5 Key technologyareas to focus on:
- 42. 5 Key technologyareas to focus on: Why these 5? • Typically under-invested areas for most organizations • Areas where developers/operations folks are constantly reinventing the wheel • Important key components of DevOps technology and practices • Mastering these areas will lead to better: – development velocity – reduced RTO/RPO – better cost management – reduction in ”fire from the hip” data-less infrastructure/application tweaks – improved security/governance/compliance
- 43. 5 Key technologyareas to focus on: • Continuous Integration/Delivery • Infrastructure as Code • Monitoring/Metrics/Logging/APM • APIs/Microservices Management • Communication & Collaboration

- 45. FIN, ACK Some takeaways: • By stepping back and looking at the big picture of how we were working we were able to drive numerous improvements over the years • By automating and *as-a-Service-ing as many work flows as possible we remove the majority of waiting, which was a majority of the overall time • DevOps: Every company will have their own unique culture but the practices are looking fairly consistent • DevOps: By investing in tools you can standardize on you remove the burden of developers needing to figure out how they will solve these problems on their own • DevOps: If culture isn’t driven from the top down it rarely will work out
