Running Stateful Services on Kubernetes

In the microservices era, stateful applications have almost become second class citizens. Containers emphasize ephemerality, forcing DevOps teams to find new solutions for managing application state. Kubernetes began offering support for stateful applications through StatefulSets and other API objects, but this is only part of the solution. Running resilient and scalable stateful services on Kubernetes involves all aspects of your deployment, from the underlying hardware to Pod update strategies.
