eBPF for Continuous Profiling: Parca and Beyla

24/7 whole-cluster profiling without instrumenting apps. Parca + Beyla modern stack for performance observability.

Beyla generates OpenTelemetry traces from existing apps without changes. Via eBPF, observes HTTP/gRPC/DNS. When to use and when SDK.

Parca profiles the whole cluster 24/7 with minimal overhead. When it makes sense and how to interpret flame graphs for real debugging.

The sidecar-or-not debate resolved with two options: Istio Ambient and Cilium Mesh. Operational comparison and which fits your team.

cAdvisor was the historical default but today isn’t enough. How to combine eBPF, Kubernetes metrics, and APM for real container observability.

Cilium offers sidecar-less service mesh via eBPF. When it beats Linkerd/Istio and when its novel approach has limits.

Falco watches the kernel and detects anomalous behaviour without instrumenting apps. When it makes sense, how to integrate it, where ops hurts.

eBPF lets you run safe code inside the kernel for tracing, networking, and security. Why it’s the foundation of modern observability tooling.

Cilium replaces iptables with kernel eBPF programs, radically changing Kubernetes networking performance and capabilities.

Pixie uses eBPF to auto-instrument Kubernetes clusters without code changes. A practical guide and comparison with Prometheus + Grafana.
