Guide to Kubernetes StatefulSet – When to Use It and Examples

Kubernetes StatefulSets are workload objects that simplify the deployment of stateful applications by providing reliable replica identifiers, stable storage access, rolling updates in a guaranteed order, and consistent network identities. They are useful for managing state in your cluster and should be used when deploying an application that requires stable identities for its Pods. StatefulSets ensure that critical replicas aren't replaced after scaling or rescheduling Pods.
