TALKS: TALK #1: "How to be (successful at being) wrong" Speaker: Russ Miles, CEO at ChaosIQ Being wrong is often seen as the worst thing that can happen™, especially when you architect, build, and run business-critical applications and services. But the increased velocity of modern software development, plus the increased need for systems to be resilient, reliable, and right has increased the pressure on teams, and in particular architects, exponentially. Never before have software owners had such an opportunity, or the power, to be wrong. We need to get better at being wrong. Russ Miles discusses the tools and techniques he uses to turn inevitably being wrong into being successful at being wrong. Being wrong can be turned to your advantage, and Russ shares stories of how this has happened and also the challenges to look out for. The myth of always being right when you architect, build, and operate software is over. You’re going to be wrong most of the time. Time to get better at being wrong and learn how to turn accidents such as outages into opportunities. BIO: Russ Miles Russ Miles is CEO of ChaosIQ.io, where he and his team build commercial and open source products and provide services to companies applying chaos engineering to build confidence in the resilience of their production systems. Russ is an international consultant, trainer, speaker, and author. His most recent book, Antifragile Software: Building Adaptable Software with Microservices, explores how to apply chaos engineering to construct and manage complex, distributed systems in production with confidence. TALK #2: "Building KubeOne: yet another Kubernetes cluster management tool" Speaker: Alexander Sowitzki, Loodse At Loodse, we have recently announced a new open source Kubernetes cluster management tool called KubeOne. We had a vision of replacing the various imperative tools we used before, with a new single tool that would allow us to manage our clusters in a cloud native way. We wanted to be able to declare clusters in form of a manifest, just like our workload, and have a tool that would bring us a ready-to-use cluster. But how to go about building such a tool? There are many existing tools as well as solutions and that was precisely out problem. It's hard to pick the right one that would satisfy all our requirements. That’s why we decided to build a new tool atop of solutions like kubeadm and Cluster-API. This talk is about building a new cluster management tool and the challenges this presented us with. BIO: Alexander Sowitzki Living in Hamburg, Alex works as an SRE at Loodse and helps customers getting started with reliable and highly-available Kubernetes clusters. He joined the KubeOne project since he believes this project can help to jumpstart many other projects. Loving to combine embedded systems and clustering, his pet project is writing user space drivers that expose functionality to the cluster and run complex event processing with them. He also does things with less computers: Avionics, scuba diving, painting hardly recognizable things and ever changing special topics.
