## AI overview

The article explains how a monolithic Cloudflare Worker becomes a deployment bottleneck at multi-tenant SaaS scale. It presents a modular gateway-and-feature-worker architecture using service bindings, discusses image optimization and multi-CDN differences, and covers versioning, staged rollouts, testing, and synthetic monitoring.

## Source excerpt

At multi-tenant SaaS scale, a monolithic edge worker creates deployment coupling and broad blast radius. The article presents a modular Cloudflare Workers architecture using service bindings, with image optimization as a worked example of per-tenant format negotiation and device-aware sizing. It covers multi-CDN differences, staged releases, configuration, and testing. By Chintan Tank
