Kubernetes Pods Are Not New Servers

A while ago I started Docker & Kubernetes: The Practical Guide on Udemy. I got through about half, then stopped when the Kubernetes section began — it did not feel relevant yet.

At my current job I keep hearing Kubernetes terms, so I picked the course back up. First surprise: I always thought a new pod meant a new tiny server — a small EC2 or Azure VM, one per pod.

Not quite. You provision nodes (servers) first. Kubernetes then schedules pods onto them and gives each pod a slice of that machine’s CPU and RAM. Many pods can share one node.

Nodes are the hardware pool; pods are workloads placed on top. That clicked for me.
