Are there a high number of customers that use the agent? Im not used to the ‘agent’ concept coming from vanilla kubernetes

I see a few common configurations depending on the number of nodes in a cluster: 1 node: 1 server 2 node: 1 server + 1 agent 3 node: 1 server + 2 agents OR 3 servers 4/5 nodes: 3 servers + 1/2 agents 7+ nodes: 3 etcd-only nodes, 2 control plane nodes, 2+ remaining agents (this is a advanced configuration where you need to scale etcd (DB) load separate from K8S control plane traffic/load, and then you run your workloads/containers exclusively on the agent nodes)

thanks !
