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.
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.
Learn how an eBPF/XDP-based NAT Layer 4 load balancer works by building one from scratch. We implement simple connection tracking, deterministic hashing, and IP/MAC rewriting with a small, easy-to-follow example.
Learn how to build an eBPF/XDP firewall that filters packets by IP ranges using BPF_MAP_TYPE_LPM_TRIE and longest-prefix matching.
