The Evolution of WebAssembly in the Cloud Native Stack

WebAssembly (Wasm) is no longer confined to the browser. As microservices look for ways to cut startup latency and decrease memory consumption, Wasm provides an attractive runtime. It compiles fast, isolates memory fully, and loads in milliseconds.

In this post, we explore how platforms like Spin and tools like Wasmtime are changing the architecture of cloud native apps.

// Example Wasm component logic in Rust
#[plugin_fn]
pub fn hello(input: String) -> FnResult<String> {
    Ok(format!("Hello, Cloud Native! Output: {}", input))
}
