StatefulSets

StatefulSets are a way to manage groups of containers in Kubernetes, particularly for applications that need to remember their state, like databases. Unlike regular deployments, StatefulSets ensure that each container has a unique identity and stable storage. This means that even if a container is restarted or moved, it retains its data and configuration. StatefulSets are crucial for applications requiring ordered deployment, scaling, and reliable storage, making them ideal for services like Cassandra or MySQL, where data integrity and order are vital.
