Watch Marko, Robert, Nabarun, Varsha Narsing and Mangirdas' Workshop at KubeCon + CloudNativeCon EU 2025

While Kubernetes transformed container orchestration, creating multi-tenant platforms remains a significant challenge. kcp goes beyond DevOps and workload management, to reimagine how we deliver true SaaS experiences for platform engineers. Think workspaces and multi-tenancy, not namespaces in a singular cluster. Think sharding and horizontal scaling, not overly large and hard to maintain deployments. With novel approaches to well-established building blocks in Kubernetes API-Machinery, this CNCF sandbox project gives engineers a framework to host and consume any kind of API they need to support their platforms.

In this hands-on workshop, participants will learn how to extend Kubernetes with KCP, build APIs, and design controllers to tackle multi-tenancy challenges. By exploring real-world scenarios like DBaaS across clusters, attendees will gain practical skills to create scalable, multi-tenant platforms for their Kubernetes environments.

Speakers: Marko Mudrinic, Senior Software Engineer at Kubermatic, Robert Vasek (Clyso), Nabarun Pal (Independent), Varsha Narsing (Red Hat), Mangirdas Judeikis (Cast AI)
