The document discusses how open source principles drive innovation in DevOps by emphasizing automation, collaboration, and continuous integration and deployment workflows. It highlights the importance of culture in fostering trust and cooperation within organizations, as well as the role of various tools and governance models in supporting these practices. Open source not only contributes code but also provides guidance on leadership, transparency, and incentives that enhance DevOps efforts.

- 5. A typical DevOps workflow
- 6. Tools for operations*/infrastucture Containerized infrastructure Orchestration Policy-based governance Configuration management Automation Packaging Updates * But they bleed into developer land!
- 7. Infrastructures evolve for cloud-native Monolithic app container Scale up by adding hardware resources Limited scale out through clustering Distributed, networked, containerized services Scale out by orchestrating services Faster iteration and release More robust RHEL APP APP SINGLE-HOST APPS MULTI-HOST APPS
- 8. Infrastructure layer: A Cloud Platform for Microservice Cloud Apps Provision apps from service catalog Orchestrate and place apps Run composed microservices in containers Provide dynamic, programmable infrastructure OPS MANAGEMENT AND SERVICE CATALOG (e.g. RED HAT CLOUDFORMS) CONTENT, ENTITLEMENT, AND LIFECYCLE (e.g. RED HAT SATELLITE) SERVICE SCHEDULER/ORCHESTRATOR (e.g. KUBERNETES) PaaS (e.g.OPENSHIFT) RED HAT ENTERPRISE LINUX OPENSTACK PLATFORM COMPUTE STORAGE NETWORK (e.g. OPENSTACK, CEPH, OPEN DAYLIGHT) RHEL ATOMIC HOST GUEST RHEL ATOMIC HOST GUEST Red Hat CloudForms Monitoring Docker Image Red Hat CloudForms Orchestration Docker Image Red Hat Satellite Content Docker Image Red Hat JBoss AMQ Docker Image App DB Docker Image Red Hat JBoss BRMS Docker Image

- 25. PaaS provides an integration point
- 26. DEVOPS: THE WHAT & THE WHY CULTURE of collaboration valuing openness and transparency
- 28. Our culture is too difficult! Really? Consider post war Japan. https://leanhomebuilding.wordpress.com/page/4/
- 29. Impose a culture of: Empathy Trust Learning Cooperation Responsibility ?
- 31. Issues with just “changing culture” ● Lack of agreed-to model of what “right” culture looks like ● Different organizations require different behaviors ● Culture change is difficult to measure and quantify ● Culture is very hard to impose ● Culture is an output, not an input
- 32. Culture = f (l, o, i, t, …) where: l = leadership o = organization i = incentives t = trust … = many other things Open source offers guidance
- 33. Leadership and vision but no one organizational structure Multiple models work but characteristics need to fit the project, participants, and vision
- 34. Solve specific problems Open source projects often begun because of an individual’s interest or issue DevOps projects (often) benefit by tackling low surface area problem cases (But, like open source, DevOps can become the default)
- 35. Transparency Who made changes? When and why did they make them? What’s the state of the project? What’s the state of the system? It’s the expectation for both open source and DevOps
- 36. Rich communication flows matter Open source projects have been forced to deal with distributed (cross-timezone) teams Tools vary by teams Video getting better F2F time still a big plus
- 37. Don’t fear failure Open source innovation highly driven by experimentation One of the points of DevOps is to enable better experimentation If it doesn’t work, move on (But fast failures)
- 38. Incentives matter Open source projects (tend to) reward based on merit and contribution Incentives in DevOps organization (advancement, money, recognition) need to reward trust and cooperation Individual has control over their own success
- 39. Open source is driving DevOps But it’s more than the code!
