Multi-cluster topologies, spanning multiple regions and clouds, are becoming increasingly popular for deploying applications with strict resiliency requirements. However, this architecture introduces new connectivity challenges: How can seamless Pod-to-Pod communication across clusters be achieved? How does service discovery work in a multi-cluster setup? This session will provide the answers.

This talk covers the key requirements, traffic patterns, and available solutions within the CNCF ecosystem for multi-cluster networking. A demo will showcase how Cilium, a CNCF-graduated project, simplifies inter-cluster connectivity using its Cluster Mesh feature.
