Managing Fleets of Kubernetes Clusters with GitOps

Managing Fleets of Kubernetes Clusters with GitOps

VSHN AG, from Zürich, has a small team of around 35 full-time DevOps engineers. They manage thousands of Kubernetes and OpenShift clusters 24/7 on behalf of their customers using the GitOps approach. This helps them ensure that applications, settings, and security configurations are up-to-date at all times. At VSHN we have created our own "secret sauce", a suite of open-source tools called Project Syn to achieve what was previously considered unfeasible. Project Syn is extensible, with hundreds of components ready to use for the most remote use cases. In this session, aimed at DevOps and Kubernetes engineers, you will learn how to use Project Syn to maintain your fleets of Kubernetes clusters using a 100% GitOps approach.
