“Kubernetes is an open-source
platform designed to automate
deploying, scaling, and operating
application containers."
Initial release: 7 June 2014

containers: present day

19. @bridgetkromhout #devopsdays
containers
treat as a tool, not a goal
be aware of complexity

20. @bridgetkromhout #devopsdays
kubernetes

21. @bridgetkromhout #devopsdays
Massively scalable fault-tolerant
distributed systems require a
significant engineering effort to build
and operate; complex socio-technical
systems are even more challenging.
Computers are easy;
people are hard

kubernetes
orchestration is only one part
wider ecosystem considerations

35. @bridgetkromhout #devopsdays
silos are for grain
not actually devops
still computers
