Service

I. Workers

1. A serverless platform for running JavaScript, TypeScript directly on Cloudflare's global edge network (in 330+ cities worldwide).
2. Code runs in lightweight V8 isolates (tiny, isolated sandboxes based on Chrome's V8 engine) — extremely fast startup (often <5–10 ms cold starts), low latency, and automatic scaling.
3. Handle HTTP requests, build APIs, rewrite responses, add logic at the edge (e.g., authentication, routing, caching), serve frontends, or act as middleware/entrypoints.

II. Containers & Sandboxes

1. All Containers on Cloudflare are deployed with and accessed via Workers.
2. Container instances are launched on-demand in response to requests from a Worker, and can be put to sleep after a configurable timeout.
