Kubernetes isn't the only orchestrator that exists. Here's some features I wish it had youtu.be/9N9IOpyl3v8

Borg is widely adopted because of Google’s org chart and culture From everything I’ve heard it’s overly complicated (feature creep) but internal teams have been layering on top of layers to make specific things easier K8s tries to layer & be flexible (eg deployments) which doesn’t layer well

This is why you see alternative options in k8s. Things like Argo rollouts. Same primitives, different opinions K8s deployments are good enough for a lot of things but once you need something else it is more work than it should be

I wish k8s had a faster, in-memory db option like borg (I don’t think it uses that anymore) Borg scaled to 10k clusters by vertically scaling single masters at the cost of downtime for data replication during failover

One aspect of k8s I am unhappy with is that we did not see an emergent ecosystem of specialized workload abstractions/controllers. It's just too technically tedious, still.

It's true that getting rid of things in Borg is nigh impossible - someone is using EVERY feature (even when that feature literally does nothing anymore :) Google has a high tolerance for "exposed wiring" sorts of UXes, which is not true in the wider world.
