quickly recognized Ku- bernetes’ ability to drive a more agile, cloud native and microservices-centric strategy, in solving the most complex of infrastruc- ture management challenges. When it came to Booz Allen Hamilton KubeEdge and K3s seemed the most natural starting point, given the device-centric use case. After assessing other leading Kuber- netes distributions, it was clear that many stayed
