https://www.lucavallin.com/blog/tags/networking Platform Engineer at Xebia, focused on AI platform engineering - the infrastructure behind reliable, observable, scalable AI and cloud-native workloads. I work primarily in Go and Google Cloud, with deep experience in Kubernetes, containers, and end-to-end observability - and a strong interest in networking and lower-level systems work in Rust. My current focus is the platform layer beneath AI: inference serving infrastructure on Kubernetes, AI gateway and MCP connectivity, agentic workload orchestration, and end-to-end observability for GenAI systems. My broader experience is full-stack: strong on backend, with solid frontend and mobile knowledge. I contribute to open source, write on my blog, and pick up the occasional talk, training, or meetup when something interesting comes up. I'm a Google Developer Expert (GDE) and a CNCF Ambassador. For a deeper dive, see my blog. If you're new to open source, check out Verto.sh. For mentorship, I'm on Mentorcruise. Outside of work, activities like photography, motorcycling, playing a handpan and cleaning litterboxes keep me occupied 🐈. en-us Luca Cavallin Luca Cavallin Thu, 02 Apr 2026 00:00:00 GMT https://www.lucavallin.com/blog/google-cloud-networking-101-the-comprehensive-tldr https://www.lucavallin.com/blog/google-cloud-networking-101-the-comprehensive-tldr A comprehensive but quick walkthrough of everything you need to know about GCP networking: VPCs, subnets, routing, firewalls, Shared VPC, GKE networking, load balancing, Cloud NAT, hybrid connectivity, VPC Service Controls, DNS, packet inspection, and how to operate all of it. Written for engineers who need a solid mental model in 15 minutes.

This practical tour explains why eBPF matters now, how programs are compiled, verified, JITed, and attached to events, and how maps and ring-3 buffers move data. You'll leave with simple demos and a clear mental model to start experimenting.

This guide breaks it down, starting from the fundamentals of Linux networking and container isolation. We then dive into the complete Kubernetes model, explaining everything from Pod IPs and CNI plugins to Services, NetworkPolicy, and Ingress, providing a clear end-to-end map of how connectivity works in your cluster.

It's not magic! The internet relies on open standards and precise addressing. I wanted to refresh my knowledge of networking fundamentals and the TCP/IP suite of protocols, so I went through a few resources and later made this post from my notes, covering common protocols (IP, TCP, UDP, DNS, BGP, NAT, DHCP, IPSec) and explaining how everything fits together.
