StatefulSet [glossary]deterministic

A StatefulSet manages deployment and scaling of a set of Pods, with durable storage and persistent identifiers for each Pod.

fundamentalcore-objectworkloadstorage

Manages the deployment and scaling of a set of [Pods](#gloss:pod), *and provides guarantees about the ordering and uniqueness* of these Pods.

Like a [deployment](#gloss:deployment), a StatefulSet manages Pods that are based on an identical container spec. Unlike a Deployment, a StatefulSet maintains a sticky identity for each of its Pods. These pods are created from the same spec, but are not interchangeable: each has a persistent identifier that it maintains across any rescheduling.

If you want to use storage volumes to provide persistence for your workload, you can use a StatefulSet as part of the solution. Although individual Pods in a StatefulSet are susceptible to failure, the persistent Pod identifiers make it easier to match existing volumes to the new Pods that replace any that have failed.
