Module 04: Storage in Kubernetes

Storage is the hardest part of any distributed system. In this module, we will learn how to persist data in a world of ephemeral containers. We will cover the core concepts of Persistent Volumes (PV), Claims (PVC), and how to automate provisioning with Storage Classes. Finally, we will dive into StatefulSets for running complex databases.
