eBPF

eBPF is a Linux kernel technology that runs verified programs to observe or control selected system events.

What is eBPF?

eBPF is a Linux kernel technology that runs verified programs to observe or control selected system events. It is part of the practical vocabulary used by administrators, developers and IT teams. Understanding it helps identify where the technology sits in an architecture and what problem it is intended to solve.

What is it used for?

It is mainly used to low-level observability, networking, security, and performance. In production, its usefulness depends on the surrounding configuration, compatibility requirements and operational constraints.

How to recognize it in practice

You may encounter eBPF in product interfaces, configuration files, logs, API documentation, network diagrams or troubleshooting procedures. Always check the context before changing a setting based only on its name.

Points to watch

EBPF programs and privileges should be tightly controlled on sensitive systems. Test changes, document the previous state and keep a rollback path for production systems.

In short

eBPF = a Linux kernel technology that runs verified programs to observe or control selected system events. Its main value is to low-level observability, networking, security, and performance.
