Cilium

Service mesh adoption dropped from 50 to 42 percent as the ecosystem pivots away from sidecars. This guide covers Istio Ambient Mesh GA, Cilium eBPF mesh after Cisco's Isovalent acquisition, Linkerd's licensing controversy, AWS App Mesh deprecation, Kubernetes Gateway API, zero-trust networking, and the convergence reshaping cloud-native communication.

A comprehensive deep-dive into eBPF technology for cloud-native observability in 2026, covering kernel-level tracing, network visibility, security monitoring, continuous profiling, and production deployment patterns with tools like Cilium, Tetragon, Grafana Beyla, and OpenTelemetry integration.

The Kubernetes Gateway API for 2026: the resource model, migrating from Ingress, and Envoy, Istio, Cilium, NGINX, Traefik and Kong compared.

A deep technical exploration of eBPF for high-performance networking and performance engineering in cloud-native environments, covering XDP, tc BPF, eBPF-based load balancing, service mesh data planes, cloud provider CNI integrations, and production case studies from Meta, Cloudflare, and Netflix.

The definitive 2026 guide to service mesh in cloud-native architectures. Covers Istio Ambient Mesh, Linkerd 2.17, Cilium Service Mesh with eBPF, sidecar vs sidecarless architectures, mTLS zero-trust networking, Gateway API, multi-cluster mesh, traffic management patterns, observability, and migration strategies for production Kubernetes environments.
