A CDN puts copies of your content on servers near your users so the bytes travel a short distance instead of crossing an ocean every request. The thing most people miss: the bottleneck usually isn't bandwidth, it's latency, and latency is bounded by the speed of light.

A deep technical guide to building low-latency, globally distributed systems on edge runtimes, from CDN functions to stateful Durable Objects.

Hard-won lessons on running Kubernetes at scale, from cluster architecture and RBAC to cost optimization and real production pitfalls.

GPUs get the headlines, but inference serving, networking, and observability are where AI systems actually win or lose. Here's what the stack looks like now.
