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

I wish Kubernetes did less. Mesos was a thin layer of resource management & platforms (aka frameworks) had all the opinions on how jobs should run The biggest downside of Mesos was Zookeeper just like the biggest downside of K8s is etcd. If that wasn't there k8s would scale and be easier to manage

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

If anyone runs nomad in production I’d love to hear your thoughts about what you like and don’t like about it It seems like a good balance between the complexity of k8s without giving up on all the flexibility

We ran nomad for several years, now on EKS. I like to say that "k8s has an orchestrator, nomad IS an orchestrator." Like, that's all you get. Anything else you have to bolt on yourself. Less about "flexible" and more about "missing". It was an ok container stepping stone, but no ecosystem at all.
