Best of 2025: eBPF: The Silent Power Behind Cloud Native’s Next Phase

Let’s start at the beginning. eBPF (extended Berkeley Packet Filter) is a technology built into the Linux kernel that allows sandboxed programs to run safely inside the kernel itself. Originally, it was ...

eBPF: The Silent Power Behind Cloud Native’s Next Phase

eBPF is quietly reshaping cloud native computing, powering service meshes, observability, networking, and security directly in the Linux kernel. By reducing sidecar overhead, enabling zero-instrumentation telemetry, and enhancing runtime protection, eBPF is ...
