StatefulSet

A StatefulSet is a Kubernetes resource that manages a group of applications requiring unique, persistent identities and stable storage. Imagine a set of servers where each has its own dedicated identity and data, so they can be individually addressed and retain information even if they restart. StatefulSets ensure each instance gets a consistent name and storage, making them ideal for databases or other stateful services. They handle deployment, scaling, and updates carefully to preserve the continuity and data integrity of each unit, providing stability and predictability in complex systems.
