The Gravity of Kubernetes

Before Kubernetes, there was no standardization around a specific distributed systems platform. Just like Linux became the standard server-side operating system for a single node, Kubernetes has become the standard way to orchestrate all of the nodes in your application.

First Impressions: Asus Tinkerboard and Docker

I’ve spent many hours playing with both 32-bit and 64-bit ARM System-on-Chip (SoC) boards, so you may be wondering why I ordered another – the Asus Tinkerboard. Well here are my first impressions with the board as I try to get Docker and Kubernetes up and running.

The feature is very smart so you may not have realized it, but it knows a good bit about what you could type.
