To keep up with infrastructure growth, companies around the world are managing an increasing number of kubernetes clusters. Enforcing kubernetes native network policy at scale is already hard enough within a single cluster. Extending this to multiple clusters is even more challenging.

Depending on the shape of your infrastructure, your cross-cluster policy requirements may be unique, and there’s no one-size-fits-all configuration. In this talk, we’ll dive deep into how different solutions work in cilium to understand sources of potential bottlenecks. We’ll discuss Clustermesh, KVstoremesh, DNS-based FQDN policy and a custom variant of KVstoremesh Datadog leverages while meshing at scale. Specifically, we’ll discuss how factors like the number of pods, identities and pod churn will impact scalability and time to policy enforcement. Join us if you’re curious about understanding the latest in cross-cluster policy and leave with actionable insights you can apply to your infrastructure.
