A performance comparison of three prominent Open Source service meshes Istio, Linkerd, and Cilium | Discovering the fastest service mesh and sharing our comparison experience

Cilium is an innovative open-source project that redefines networking and security for containerized applications. By leveraging the power of eBPF (extended Berkeley Packet Filter), Cilium provides efficient networking and transparent security capabilities for modern cloud-native environments. Readers exploring Cilium can gain insights into advanced networking concepts, such as service mesh architectures, network policy enforcement, and distributed application security.
