Kubernetes has a lot going for it, but it isn't (yet) anywhere close to Borg in terms of scalability. 5000 maximum hosts in a cluster is a drop in the bucket for a Borg cluster. Google was publicly talking about 10,000 machines as the median size almost 5 years ago.
As for Prometheus, I like the rules engine VERY much (unsurprising, since they basically reimplemented borgmon, there). I'd take Viceroy any day over Grafana, though.
- meddlepal 7y agoI have deep experience with operating Kubernetes and no experience with Google's Borg but I imagine Borg is significantly more challenging to operate? Kubernetes is designed to be a workload scheduler that a three or four person team can operate.
- packetslave 7y agoI imagine if you're Borg SRE, you'd say "yes, it's significantly more challenging to operate", but for the tens of thousands of other engineers? Not really, although there was a LOT of copypasta in terms of building new configs for services.
