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

orchestrating containers: a tool, not a goal

will produce a design
whose structure is a copy of
the organization's
communication
structure.”
Mel Conway

résumé-driven development

cloud choices:
focus on outcomes
not on tech

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

You: learning a lot in a k8s 101
workshop at a conference
Your co-workers at home:
being sad with all the FOMO*
* Fear of missing out
Typical Scenario

If k8s democratizes distributed
systems, how do we democratize
learning about k8s?

open-source k8s training, of course!

“k8s 101” - what do we mean?
1.start with the familiar
2.limit unnecessary options
3.build understanding incrementally

container.training
- Walk through operating
microservices on k8s
- Learn concepts and terms through
hands-on exploration

future
“What’s next?”

orchestration is only one part
wider ecosystem considerations
