Edge Compute
Compute@Edge for edge logic
Compute@Edge is a serverless platform running WebAssembly across a global edge network with cold starts < 50 microseconds - 1000x faster than Lambda@Edge. It supports Rust, JavaScript/TypeScript, Go, and AssemblyScript compiled to Wasm for secure, sandboxed execution. It is ideal for personalization, A/B testing, auth, geolocation, and data transformation at the edge without an origin round-trip.
