Scaling Network Policy Enforcement Beyond the Cluster Boundary with Cilium

Learn about cross-cluster network policy enforcement in a technical conference talk that explores how companies can effectively manage network policies across multiple Kubernetes clusters using Cilium. Dive into various solutions including Clustermesh, KVstoremesh, and DNS-based FQDN policy, with special attention to Datadog's custom KVstoremesh implementation for large-scale deployments. Understand the critical factors affecting scalability and enforcement timing, such as pod numbers, identities, and pod churn rates. Gain practical insights into selecting and implementing the right cross-cluster policy solution based on specific infrastructure requirements, while learning how to overcome common bottlenecks in multi-cluster environments. Master the complexities of extending Kubernetes native network policies beyond single cluster boundaries and discover actionable strategies for improving network policy management at scale.
