+## Stateless workloads
+- Deployments and Replicasets that we had deployed so far are stateless workloads.
+- There is no state related information stored at Pods/Service, so request from kube-proxy via serivce resource can be routed to any of the Pod in the cluster.
+- This constitutes stateless workload.
+- Next section is to create a Stateful workload.
