eBPF (Extended Berkeley Packet Filter)

eBPF (Extended Berkeley Packet Filter) is a revolutionary technology that allows sandboxed programs to run in the Linux kernel without modifying kernel source code or loading kernel modules. It enables developers to safely and efficiently extend kernel functionality for networking, security, observability, and tracing purposes through custom programs that execute in a virtual machine within the kernel.

Companies want eBPF expertise NOW because it's becoming the standard for cloud-native observability and security, enabling real-time monitoring and enforcement without performance overhead. With the rise of microservices and containerized environments, eBPF provides deep visibility into distributed systems while major players like Datadog and Cilium are building entire product ecosystems around this technology.
