Microk8s monitored by Prometheus and scaled up accordingly by a Mesos service. And for a powerful system this is fine (again I have example where I have seen this mess up for chromium and vscode where even on better system so GUI issues, resource hogging) but for a a raspberry-pi 4 with microk8s with no pods seeing the load-average hit close My company originally explored IoT solutions from both Google and AWS for our software however, I recently read that both MicroK8s and K3s are potential candidates for IoT fleets.
