Beyond the Origin: How Cloudflare Workers Forge High-Performance APIs

As engineers, we spend a lot of time optimizing our origin servers. We scale them up, add more instances, and fine-tune our database queries. But what if the biggest performance gain wasn't on our origin server at all? What if it was somewhere between our user and our server? For years, the model has been simple: a user makes a request, it hits our infrastructure, we process it, and send a response. This is reliable, but it has limitations. Every request, good or bad, puts a load on our servers.
