Why WebAssembly?

Second, the WebAssembly bytecode is portable . Developers only need to build it once and do not need to worry about changes or updates to the underlying Netlify serverless runtime. It also allows developers to reuse the same WebAssembly functions in other cloud environments.

Third, WebAssembly apps are easy to deploy and manage. They have much fewer platform dependencies and complexities compared with NaCl dynamic libraries and executables.

Finally, WebAssembly is polyglot. C/C++, Rust, Swift, Kotlin programs can all be easily compiled into We...

For starters, WebAssembly provides fine-grained runtime isolation for individual functions . A microservice could have multiple functions and support services running inside a microVM. WebAssembly can make the microservice more secure and more stable.
