5. © 2018 Cloud Native Computing Foundation 5 Containers Cloud Native From Virtualization to Cloud Native •Cloud native computing uses an open source software stack to: – segment applications into microservices, – package each part into its own container – and dynamically orchestrate those containers to optimize resource utilization Open Source IaaS PaaS Open Source PaaS Virtualiza- tion 2000 2001 2006 2009 2010 2011 Non- Virtualized Hardware 2013 2015 IaaS
7. © 2018 Cloud Native Computing Foundation 7 History of Infrastructure • Infrastructure as a Diagram • Infrastructure as a Script • Infrastructure as a Code • Infrastructure as a Software

13. © 2018 Cloud Native Computing Foundation 13 What is Cloud Native Infrastructure ? • CLOUD + INFRASTRUCTURE • Servers as a Service • Extreme Automation • Decoupled architecture • Encapsulate processes • Automated Orchestration

15. © 2018 Cloud Native Computing Foundation 15 NEW OSI Reference Model Software Software Software Software Data Link Physical Software Software
16. © 2018 Cloud Native Computing Foundation 16 Kubernetes in Search Trends Google Trends (2017-2020)
17. © 2018 Cloud Native Computing Foundation 17 Kubernetes CONTROLLER for { getActual() getExpected() reconcile() }
18. © 2018 Cloud Native Computing Foundation 18 Operators - etcd operator - postgresql operator - mysql operator - prometheus operator - and so on...
19. © 2018 Cloud Native Computing Foundation 19 Cloud Maturity Matrix
20. What is the lesson?
21. © 2018 Cloud Native Computing Foundation 21 Cloud Native Infrastructure Infrastructure is NOW managed by SOFTWARE
22. © 2018 Cloud Native Computing Foundation 22 Key Takeaways Stop managing Infrastructure the OLD way
23. © 2018 Cloud Native Computing Foundation 23 Key Takeaways Your Infrastructure MUST be: - Horizontally scalable - No single point of failure - Resilient and self-healing - Minimal operator overhead - Decoupled from the underlying platform
24. © 2018 Cloud Native Computing Foundation 24 Key Takeaways You are now a SOFTWARE ENGINEER
