WebAssembly vs AWS Lambda vs Cloudflare Workers: Which Actually Performs Best?

WebAssembly (Wasm) apps are faster, more secure, use fewer resources, and are smaller compared to AWS Lambda. The tests show Cloudflare Workers outperform AWS Lambda and Fermyon Cloud in terms of latency and recursion optimization due to the V8 engine and global edge network. Security is enhanced with Wasm's sandboxed environment and Cloudflare's blocking of code execution from strings. However, resource usage monitoring is limited on Fermyon Cloud compared to detailed metrics provided by AWS and Cloudflare.
