Kubernetes StatefulSets

Kubernetes StatefulSets are a type of resource used to manage applications that require stable and unique identifiers, like databases or other stateful services. Unlike regular applications that can be easily replaced, StatefulSets ensure that each instance of an application retains its identity and storage. This means if one instance goes down, the system can restart it with the same name and data, preserving the application's state. Essentially, StatefulSets help manage complex applications that need to remember their connections and data even when they are restarted or scaled up or down.
