#Networking

Cloud networking determines latency, cost, and security posture across distributed systems. Articles cover multi-cloud egress optimisation, VPC design patterns, and the networking decisions that reduce cross-cloud data transfer costs while maintaining security boundaries.

eBPF for Networking

Networking is where eBPF delivers its most dramatic performance wins. By running packet-processing logic in the kernel — at the earliest possible moment a packet arrives, before the kernel even builds its usual data structures — eBPF can filter, route, and load-balance at speeds user-space networking can't touch. It's why the networking layer of modern cloud-native infrastructure is increasingly eBPF underneath.

TLS: Where It All Comes Together

TLS is the protocol securing nearly every connection you make, and it's not a single cryptographic trick — it's the whole toolkit orchestrated into one handshake. Key exchange, certificates, signatures, and authenticated encryption each solve one sub-problem, and TLS composes them so that two parties who've never met can establish a private, tamper-proof, authenticated channel over a hostile network. Understanding the handshake is understanding how every earlier piece fits.
