eBPF is transforming Cloud Native. Co-located with KubeCon + CloudNativeCon, eBPF Day is a vendor-neutral conference that explores this transformational technology and its impact on the future of Cloud Native. By making the Linux kernel programmable, eBPF has resulted in the development of a completely new generation of tooling in areas such as networking, security, application profiling/tracing, and performance troubleshooting. No longer is it necessary to rely on existing kernel functionality; now, it’s possible to actively reprogram runtime behavior without compromising execution efficiency or safety.
