4. Agenda • Containers & Kubernetes. • The Kubernetes Promise. • Reliability Engineering. • Resilience Engineering. • Kubernetes is not perfect! • Chaos Engineering.
5. A Children’s Guide to Kubernetes
6. What is a Container? It is “a lightweight OS-level virtualization method” “stand-alone piece of executable software” “NOT a virtual machine” A container running on a machine is simply a process on the host operating system like any other.
11. container management system which is built with reliability in mind.
12. Kubernetes is a container management system which is built with reliability in mind.
13. What is the meaning of Reliability?

15. SREs are focused on efficiency, automation, and reducing costs, taking manual and repetitive tasks and automating them.
16. Resilience is here the ability to return to the steady-state following a perturbation. Resilience Engineering is about the characteristics of resilient performance per se, how we can recognise it, how we can measure it, how we can improve it.
17. A distributed system on production needs to be resilient in order to be reliable and this is precisely a target that we Software Engineers, Systems Engineers, Site Reliability Engineers and Chaos Engineers always aim.
18. Accidents happen :(
19. Black Swans are events that comes as a surprise, have a major effect, and are often inappropriately rationalized. The term is based on an ancient saying that presumed black swans did not exist
21. The World is Chaotic! Black swans take our systems down and keep them down for a long time. Laura Nolan, SRE in Slack
22. Accidents in Kubernetes happen :O
26. Chaos Engineering It is the discipline of experimenting in production on a distributed system in order to reveal their weakness and to build confidence in their resilience capability. https://principlesofchaos.org/
27. Chaos Engineering It is deliberately inducing stress or fault into software and/or hardware as a way of learning/verifying things about systems. https://www.gremlin.com
28. 2008 Chaos Engineering began at Netflix 2010 Chaos Monkey was launched 2018 A lot of resources for Chaos Engineering. 2014 Role of Chaos Engineer was created. History of Chaos Engineering Kolton Andrus
30. I want to emphasize that both sides of the equation [unit, regression and chaos side] are required to get you the level of availability you want.
31. Phases of Chaos Engineering Taken from https://blog.codecentric.de/en/2018/07/chaos-engineering/
37. Picasso Napkin Story Mark Manson .. The Subtle Art of Not Giving a F*ck
