Cloudflare uses a V8-powered architecture instead of traditional containers in their Workers platform to deliver sub-millisecond serverless latency and serve a large number of tenants independently. This architecture leverages V8 isolates, which are lightweight, fast, and provide strict code isolation within the same OS process. While this approach offers significant performance advantages, it is limited to supporting only JavaScript and WebAssembly and may not suit compute-intensive or long-running tasks.
