Building ASGI Microservices with Cloudflare Python Workers in Production

Python microservices have historically been tethered to centralized infrastructure, whether that means containers running behind a load balancer in a single region or Lambda functions cold-starting in one AWS availability zone. Cloudflare Python Workers flip that model by running ASGI frameworks like FastAPI directly at the edge, and this guide walks through building a production-ready aggregation microservice that handles authenticated fan-out, caches results in Workers KV, and deploys.
