Interesting that they use Kubernetes exclusively for edge computing resources (as opposed to their cloud architecture). Never really considered this approach before.
If you decide to play around with it, we use RKE to build and manage the k8s environments locally.
We use K8s in the cloud as well! Our entire control plane for the IOT activity runs there. The rest of the engineering teams have a mix of solutions, but many are moving to K8s as well.
