Multiple worker VMs per physical host? Why?
- xyst 2y agoMostly for easier segregation of workloads. Some of the IoT shit that runs on this cluster I segment it off through k8s and network policies. Also most workloads wouldn’t need to use all cores or memory on that machine (one machine has 128G)

Depending on your threat model that could make sense. > Also most workloads wouldn’t need to use all cores or memory on that machine (one machine has 128G) What? Limiting CPU or memory use of a pod is one of kubernetes' core competencies; just tell it what each thing needs and it handles all that for you.
