"A key reason behind Amex's adoption of WebAssembly is that WebAssembly demonstrated superior performance metrics compared to containers."
Wasm faster than containers? I guess they mean under there specific circumstances. Rust or C on a Linux container running machine code should definitely be faster than Wasm bytecode.
I wonder what source language they are using that will be compiled to WebAssembly.
I also wonder how they built their FaaS infrastructure.
A possibility is that they used the open source Firecracker (written in Rust) which powers AWS Lambda.
