Topics 1 - What's included in Kubernetes (by default)?

We’ve seen quite a bit of survey data recently that shows usage of Kubernetes is growing quite rapidly. If somebody says they are “using Kubernetes”, by default, what functionality do they have available to them?



Topic 2 -  What core “platform” elements aren’t included with Kubernetes?


Container Runtime (e.g. docker, rkt, oci)

Container Registry

Advanced Networking

Persistent Storage

Monitoring, Logging

Backup tools for Kubernetes or the applications running in Pods.


Topic 3 - What are some of the standard ways to plug in those pieces?


Container Runtime - CRI (Container Runtime Interface)

Registry - Many 3rd-party options

Networking - CNI (Container Network Interface) 

Storage - CSI (Container Storage Interface)

Logging / Monitoring - Sidecar Containers


Topic 4 - What does a company get with a "distribution" vs. "platform" vs. "public cloud service"?


Tectonic (example)

OpenShift (example)

Google Container Engine (example)
