Level 3 | ICC Capital Suite 7-9

Considering an Istio multi-cluster setup? Hear real-world lessons on balancing security with operational complexity, scaling configurations to hundreds of clusters, and designing for resilience and observability. Lessons learned from managing 244 clusters serving 570 million requests per day.

Adopting Istio in Kubernetes deployments often starts as an exciting journey, but challenges arise when scaling to support millions of services—issues not covered in basic guides.

This talk dives into the complexities of implementing a multi-cluster Istio service mesh at scale, covering a hub-and-spoke model. Key challenges include: ensuring secure client isolation; load balancing across different types of clusters; managing failover; and automating cluster lifecycle.

Whether you're planning your first multi-cluster Istio deployment or struggling with management at scale, this talk will provide actionable strategies to overcome the pitfalls of large-scale service mesh implementations.
