Using microk8s 1.18.6, single node, Ubuntu 20.04, on a machine having 32GB and AMD FX-8320 (8 logical cores)
Some dev execises, such as a multinodes Cassandra cluster requires more pods than computing resources.
So far, it seems my single-node microk8s setup is able to provide the requested resource. I am just curious how microk8s manages to run many more pods than the available CPUs.
In the context of a single physical homelab server, is there a boundary somewhere when a multi-nodes (several KVM VMs) setup would be superior to a single node?
For now my current machine is pretty modest (32 GB, 8 logical cores). But if hardware resources is an issue it is possible to use a more powerful workstation with more cores and more RAM. But still a single physical machine.
