Building an eBPF/XDP L2 Direct Server Return Load Balancer from Scratch
In this tutorial, you will learn how to build an Layer 2 DSR load balancer using eBPF/XDP, where backends send responses directly back to clients bypassing the load balancer.
Why Does My eBPF Program Work on One Kernel but Fail on Another?
In this tutorial, we look at why eBPF programs can fail across kernel versions due to changes in structs, tracepoints, and function layouts. We look at examples of how these differences cause portability issues and how BPF CO-RE, BTF and vmlinux.h address them.
Hands-On Firecracker: microVMs From First Principles to Production
