Container - Compute unit that we can run in the cloud

Pod - One or more containers that are one unit in the cloud that could be started, stopped, or restarted.

Service - Different network services that serve the pods

Load balancers - Balance network calls to different pods

Certmanager - Handles certificates, for instance, let’s encrypt.

Ingress - Handles traffic from the external network

Volumes - External resources used by pods to keep state

ConfigMap - Configuration parameters that could be changed without restarting the pods or deployment.

Deployment - A configuration of all the terms mentioned that you use to deploy as a unit to the cluster.
