KubeCon + CloudNativeCon Europe 2019

We often hear “Storage on Kubernetes is hard” or “Don’t deploy stateful applications on Kubernetes!” Is there any truth to these statements? In this talk I separate fact from fiction.

Storage on Kubernetes can mean a lot of things. First I will start by separating three layers: 1) consuming block and file storage from a pod running in Kubernetes, 2) deploying a stateful app (like a database) on Kubernetes using storage and workload primitives, and 3) deploying a software defined storage system on top of Kubernetes to provide block or file storage. Each of these areas has a different set of challenges that are often conflated to make storage on Kubernetes appear much harder than it is.

 After separating these layers, I will help you understand what the challenges are with each of them, and how you work around them to effectively deploy stateful applications on Kubernetes.
