Whether you want to read a first introduction to eBPF, find further reading material or make your first steps to becoming contributors to major eBPF projects, eBPF.io will help you along the way. eBPF is an open community and everybody can participate and share. What is eBPF.io?ĮBPF.io is a place for everybody to learn and collaborate on the topic of eBPF. The possibilities are endless, and the innovation that eBPF is unlocking has only just begun. Today, eBPF is used extensively to drive a wide variety of use cases: Providing high-performance networking and load-balancing in modern data centers and cloud native environments, extracting fine-grained security observability data at low overhead, helping application developers trace applications, providing insights for performance troubleshooting, preventive application and container runtime security enforcement, and much more. This has led to a wave of eBPF-based projects covering a wide array of use cases, including next-generation networking, observability, and security functionality. The operating system then guarantees safety and execution efficiency as if natively compiled with the aid of a Just-In-Time (JIT) compiler and verification engine. By allowing to run sandboxed programs within the operating system, application developers can run eBPF programs to add additional capabilities to the operating system at runtime. The rate of innovation at the operating system level has thus traditionally been lower compared to functionality implemented outside of the operating system.ĮBPF changes this formula fundamentally. At the same time, an operating system kernel is hard to evolve due to its central role and high requirement towards stability and security. Historically, the operating system has always been an ideal place to implement observability, security, and networking functionality due to the kernel’s privileged ability to oversee and control the entire system. It is used to safely and efficiently extend the capabilities of the kernel without requiring to change kernel source code or load kernel modules. EBPF is a revolutionary technology with origins in the Linux kernel that can run sandboxed programs in a privileged context such as the operating system kernel.
