- 3. WE ARE IN A CAMBRIAN EXPLOSION 3
- 4. OPEN SOURCE INNOVATION DISRUPTING AS ARE ASSOCIATED PRINCIPLES AND PRACTICES Gordon Haff @ghaff4
- 6. Gordon Haff @ghaff6 MUCH IS VERY NEW 2006 2007
- 7. Gordon Haff @ghaff7 SOME IS EVEN NEWER 2006 2007 2012 2013 2014
- 8. Gordon Haff @ghaff8 COMPUTING AS PUNCTUATED EQUILIBRIA • Rapidly changing environment • Open source innovation and recombinations • Intersecting trends • Hard to predict
- 9. Gordon Haff @ghaff9 TRADITIONAL INFRASTRUCTURE& APPS Server, storage, & networking hardware Operating system Application & dependencies Application & dependencies Application & dependencies
- 10. Gordon Haff @ghaff10 (ONE OF) THE PROBLEMS Server, storage, & networking hardware Operating system Application & dependencies
- 11. Gordon Haff @ghaff11 ENTER HARDWARE VIRTUALIZATION Server, storage, & networking hardware with CPU, memory, I/O virtualization assists Hypervisor (or other partitioning methods) Application & dependencies Application & dependencies Application & dependencies Operating system Operating system Operating system
- 12. Gordon Haff @ghaff12 WHAT CHANGED REALLY? • Application components still installed within OS (e.g. yum install) • Applications still long-lived & stateful “pets” • Server sprawl to virtual machine sprawl
- 13. Gordon Haff @ghaff13 WHICH WAS SORT OF THE POINT • Improved server utilization reduced CAPEX • Without (initially) operational impact
- 14. Gordon Haff @ghaff14 JUST PULL COMPUTING OFF THE “GRID”?
- 15. Gordon Haff @ghaff15 THE DISCONTINUITY HITS • “Software is eating the world” • Digital transformation needs: • More effective software delivery • Reimagined componentized architectures • Scale • Pervasive sensors & access
- 16. Gordon Haff @ghaff16 NEEDED: A NEW PLATFORM FOR CLOUD- NATIVE APPS DEVELOPED USING DEVOPS
- 17. Gordon Haff @ghaff17 SOME APPLICATION PROBLEMS TODAY • Coordination across large teams • Brittle apps: minor changes cause major breakage • Process bogged down by big deployments • Different teams keep reinventing the wheel (in gratuitously different ways) • Hard to scale • Hard to experiment
- 18. Gordon Haff @ghaff18 CLOUD-NATIVE APPS • “Small” independent components • Accessed as a (micro)service through an exposed API • Replacable cogs (“ants”) • Reliable at the service level • Portable across hybrid infrastructures
- 19. DEVOPS APPLIES OPEN SOURCE TOOLS, PRINCIPLES, AND PRACTICES WITH: • CULTUREof collaboration valuing openness and transparency • Iterative AUTOMATION of process from development through ongoing operations • An evolving PLATFORM that optimizes for flexible, dynamic workloads
- 20. Gordon Haff @ghaff20 DEVOPS + CLOUD = INDUSTRIALIZE
- 21. Gordon Haff @ghaff21 WHAT ARE THE ELEMENTS OF THIS FACTORY? • Software-defined infrastructure • Container ecosystem • Orchestration and resource control • Developer tooling • Hybrid cloud management
- 22. Gordon Haff @ghaff22 FROM SERVERS TO DATACENTERS • Software-defined • Dynamic resource pool • Physical/private/public/hybrid
- 23. Gordon Haff @ghaff23 OPENSTACK: SOFTWARE-DEFINED INFRASTRUCTURE Linux
- 24. Gordon Haff @ghaff24 OPTIMIZED CONTAINERS: ISOLATION WITHIN OS • Linux kernel manages isolation, resource use, and security • Low overhead • Bootable, immutable, versioned filesystemtrees (OSTree) • Namespaces • SELinux • Cgroups

- 27. Gordon Haff @ghaff27 OPERATE AT SCALE: EVERYONE IS SCALING! • Not just unicorns and mammoths • Different aspects of scale: • Large scale workloads • Diverse workloads (batch and services) • Complex resource management (QoS, latency sensitivity, etc.) • Grid computing: It lives! • Orchestration and resource management
- 28. Gordon Haff @ghaff28 ROUNDING OUT THE DEV AND OPS EXPERIENCE • Developer experience and tools • Application lifecycle support (CICD, etc.) • Service catalog • xPaaS services • Build platform and “get out of the way” • Container management • Hybrid cloud management • Policy-based automation • Audit support
- 29. Gordon Haff @ghaff29 THE NEW PLATFORM Physical hardware Container resource management Container-optimized Linux Software-defined infrastructure Container runtime & tools Container/ services Container/ services Container/ services Container/ services Container/ services Container/ services Hybrid cloud management Developer tooling
- 30. Gordon Haff @ghaff30 THE CAMBRIAN EXPLOSION ISN’T OVER • Role of hardware virtualization • On-premise vs. public cloud trends • Monoliths vs. Microservices • Special-purpose hardware • Balancing innovation with stability
