ReplicationController
‣ Endpoint with DNS name ‣ Logical group of Pods ‣ Policy how to access the Pods
‣ Atomic unit of orchestration and scheduling
‣ Group of co-located containers(one node, one lifecycle)
‣ Containers share an unique IP,persistent volumes and env vars ‣ Controls Pod lifecycle
‣ Ensures that a defined nbr. of Pod instances is running
new gen: Replica Set
Deployment: Declarative update (target state description) for Pods and Replica Sets.
