Tools: Webassembly (wasm) At The Edge: Why The Future Of Serverless Is Not...

For the last decade, Docker and containers have defined how we deploy software. But as we move toward the 'Edge', the limitations of containers—slow cold starts, heavy memory footprints, and complex security isolation—are becoming visible.

The answer to these challenges isn't 'smaller containers'. It is WebAssembly (Wasm).

Originally designed for the browser, Wasm is a binary instruction format for a stack-based virtual machine. It's portable, secure, and runs at near-native speed. In the serverless world, it allows us to run 'nanoprocesses' that start in microseconds, not seconds.

WebAssembly isn't replacing Docker for everything, but for high-scale, low-latency edge computing, it is the clear winner. The transition is already happening—are you ready for it?
