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

I think nomad has something different. From what I can tell in the docs as an admin I can do something like k get pod and even if the pod is in a different cluster nomad will route me to the correct cluster to give me the information I could be wrong which is why I’m asking for someone w/ exp

You can! (WAN Federation) Hashi licensing aside, nomad is one of the lowest maintenance systems I’ve ever deployed at scale (it’s almost zero touch at Fermyon, at CircleCI it was higher touch, but we were scheduling hundreds of jobs/min and that was before it had batch raft ops)

Nomad is great! But this is Nomad + Consul, right? Has anyone tried to sync/reconcile k8s service discovery from multiple clusters in different regions to a “global” consul? I’ve seen it done with the consul mesh or atnorth south boarder. Also @kelseyhightower.com making hashinetes back in the day.

It’s been a while but I think Calico also has a multi-cluster service discovery capability. (Not sure if it’s enterprise only though.)
