eBPF 2026: How Extended BPF is Revolutionizing Linux Kernel Programmability
eBPF (extended Berkeley Packet Filter) has evolved from a packet filtering mechanism to a powerful kernel programmability layer that powers observability, security, and networking in cloud-native environments. This comprehensive analysis explores how eBPF became the backbone of modern Kubernetes networking through projects like Cilium, its role in replacing traditional iptables, and why it has become essential for cloud-native infrastructure in 2026.
