Modern applications rely on many interconnected services, and managing their communication securely and reliably takes infrastructure. Traditional service meshes such as Istio use a sidecar proxy alongside each application instance, adding CPU and memory overhead that can increase infrastructure and licensing costs as deployments grow.
Istio Ambient introduces a more resource-efficient service mesh architecture, replacing individual sidecars with shared infrastructure and optional waypoint proxies. In this session, Michael Hofmann explains how the architecture works, explores its potential cost savings and trade-offs, and examines how Ambient can coexist with traditional sidecar-based Istio deployments. Learn what the new approach means for resource consumption, operational complexity, and teams evaluating how to optimize their service mesh.

Michael Hofmann works as an independent consultant, coach, speaker, and author. He has gained extensive project experience in software architecture, Java Enterprise, and DevOps through projects in Germany and internationally. In his talk, he explores how Istio Ambient can reduce resource consumption and operating costs through a sidecar-free architecture, highlighting its benefits, challenges, and possibilities for running it alongside traditional Istio.
