BPF is the technology quietly powering the biggest names in cloud-native observability and networking — Cilium, Falco, Pixie, and Parca. But what actually is it?
In this short, we break down:
• Why user-space packet counting kills performance
• Why kernel modules are too risky for production
• How eBPF gives you the best of both worlds — kernel-level speed with sandboxed safety
• The role of the eBPF verifier and kernel hook points
If you work with Kubernetes, Linux networking, or observability tooling, this one's for you.
