Architectural & Performance Comparison Metrics

Memory Overhead

Envoy Sidecar Container per Pod (~120MB)→eBPF Kernel Mesh (~15MB per node)

70%+ memory savings

Executive Briefing: Sidecarless Zero-Trust Infrastructure

Traditional service mesh architectures suffer from the resource and operational overhead of injecting proxy containers into every pod. The advent of kernel-level eBPF routing and ambient mesh proxies allows zero-trust encryption and traffic management at near-native throughput.
