Deep dives into DevOps and Server Side topics where theory blends with hands-on examples. You can try out commands from each tutorial in the attached remote playground, either from the browser or via SSH access from your local terminal — no extra setup required.
Tutorials from outstanding independent authors proudly hosted by iximiuz Labs.
This lab teaches you how to use eBPF to transparently intercept and redirect a client's outgoing traffic to an Envoy proxy without requiring any changes to the application code. You will build a system that recovers original connection metadata via socket-level hooks and uses SO_MARK to prevent infinite routing loops, replacing traditional, complex iptables rules with a high-performance eBPF alternative.
In this tutorial, you’ll learn how eBPF applications send kernel events into user space using perf buffer and ring buffer, exploring their design, trade-offs, and performance implications. You’ll also learn how moderns solutions like Jibril handle high-throughput event delivery.
In this tutorial, you will learn how to build a IPIP DSR load balancer using eBPF/XDP, where backends from arbitrary networks send responses directly back to clients bypassing the load balancer.
