iirc Mesos was inspired by Borg. Google kept Borg secret for quite a long time, eventually releasing K8s when they started failing hard at cloud and needed to keep their foot in the door for developer mind-share. Borg's real win was the insane colocation and oversubscription it enabled, both of which K8s and all major public clouds have failed to replicate because you can't securely share bare metal between customers. and K8s ended up being too little too late, despite beating Mesos and being quite successful, because VMs had won by that point.
