Beyond the Hype: Cloud Native eBPF

summary
Explains how libbpf plus BTF realize compile once run everywhere portability so precompiled eBPF programs load on modern kernels without shipping a C toolchain, shows libbpf-go with Go 1.16 embedding to produce a single static binary, and implements a low‑overhead profiler: perf events at ~100Hz trigger an eBPF program that writes two maps (stack traces and keyed counts), exports data as pprof, and is released as the open source parka agent that runs in production.
