State of State in Containers

June 6, 2017
Application container technologies like Docker and Kubernetes have revolutionized the way in which developers can deploy and manage stateless applications. Containers are quick to launch and make efficient use of underlying compute resources. Orchestration engines like Kubernetes simplify the deployment, lifecycle, and scalability of applications. However, with all these known benefits of containers for stateless microservices, there is a common misconception that containers are poorly suited for stateful applications and databases. In this talk, we will review the history of persistent storage in Kubernetes, including current methods such as network storage and StatefulSets. Finally, we will see how emerging techniques, including CoreOS’s Operator paradigm as well as distributed storage engines like Rook.io are changing the state of state in containers.
