eBPF has revolutionized Kubernetes networking. Cilium, the leading eBPF-based container networking interface (CNI), is now emerging as a standard on major cloud providers like Google Kubernetes Engine (GKE). It provides superior scalability, security, and observability compared to traditional CNIs. eBPF also powers Hubble for network & security insights and Tetragon for runtime security enforcement. Find out how to leverage these tools to get the most out of your GKE cluster.
