The Practicalities of Deploying eBPF - John Armstrong

eBPF (extended Berkeley Packet Filter) is a feature in modern Linux kernels that allows you to write mini-programs that are attached to low-level hooks in the Linux kernel that execute based on certain events (e.g. filtering network traffic). Calico now supports eBPF as well as the standard Linux networking pipeline, providing Calico users with the choice of either option in a single, scalable platform. The performance benefits of eBPF are most significant when running particularly network-intensive or latency-sensitive workloads. However, there are trade-offs to deploying eBPF such as the requirement to use the latest Linux kernels. - This session will provide insight into common questions about eBPF: - What are some typical real-world use cases that could benefit from eBPF features? - What are the performance benefits of eBPF relative to using the standard Linux networking pipeline? - How do I know if eBPF is a good fit for my organization?
