LinuxCon + CloudOpen + ContainerCon NA 2015

Docker makes it far easier to develop and deploy programs. Kubernetes helps you build and run systems of 100s or 1000s of containers. Your system stays up while individual containers come and go as needed. But what about your data? With ephemeral containers, where does the data live?

This talk is a tour of emerging patterns for keeping state in clusters of containers. First, a review of the challenges, solutions and their tradeoffs for keeping track of things when running a cluster of ephemeral containers. We will cover both configuration management and data storage (databases, etc), and a survey of the different ways people are dealing with these challenges. Examples will be illustrated in Kubernetes, an open source cluster manager and scheduler that simplifies deploying and managing container based applications. These patterns are also helpful when running on PaaS or VMs directly.
