OPN211: How Zalando runs Kubernetes clusters at scale on AWS

Many clusters, many problems? Having many clusters has benefits: reduced blast radius, less vertical scaling of cluster components, and a natural trust boundary. In this session, Zalando shows its approach for running 140+ clusters on AWS, how it does continuous delivery for its cluster infrastructure, and how it created open-source tooling to manage cost efficiency and improve developer experience. The company openly shares its failures and the learnings collected during three years of Kubernetes in production.
