Cilium, an open-source, cloud-native solution using eBPF, can integrate with the Kubernetes Gateway API to significantly enhance API management with advanced networking, security, and observability features. It offers high-performance, programmable networking for modern cloud-native environments. This session will overview Cilium and the Kubernetes Gateway API, looking at current capabilities and how to use these technologies to enhance both north-south and east-west-style API management. Attendees will walk away with actionable advice for using state-of-the-art cloud-native tools to improve API management and a zero-trust security posture.
