WebSockets Are an HTTP Request That Stops Being HTTP
WebSockets disguise themselves as HTTP, then drop the disguise the moment they're past the firewall. That trick is the entire reason real-time works on the web — and the entire reason WebSockets break your load balancer, your thread pool, and your deploys. This post walks through the four promises of HTTP, how SSE bends one of them, how WebSockets break three, and what production teams have to rebuild because of it.

This post reverse-engineers all three architectures and gives you a mental framework for making these decisions yourself.

Most engineers treat Kubernetes like a fancier way to run containers. But that mental model will fail you when things break. This article walks through the control loop pattern, and every major Kubernetes component — pods, services, deployments, the scheduler, and ingress — through the lens of how Kubernetes actually thinks. Once you see it, you can't unsee it.
