CNCF-hosted Co-located Events Europe 2025

Transitioning from legacy monolithic applications to a modern service mesh comes with its own set of challenges, especially at scale. In this session, Yashwanth and Venkat will take you behind the scenes to explore how eBay adopted Istio for business-critical use cases previously reliant on hardware load balancers. They’ll share hard-earned insights and lessons learned from operating Istio across hundreds of clusters, tackling unique challenges in traffic distribution, and ensuring seamless business continuity during the transition.
The talk will dive into technical details, including the shift from hardware to Istio-powered service mesh, OS and kernel-level optimizations for scaling Istio to meet demanding business needs, and solutions to common pitfalls. This session offers an invaluable opportunity to learn from real-world implementations of Istio and gain practical insights on what works,and what doesn’t, when deploying service mesh at scale.
