Edge cloud computing is moving beyond heavy containerization towards lightweight WebAssembly (Wasm) runtimes. Wasm engines execute sandboxed code at a fraction of the memory footprint of Docker containers.
This runtime profile allows cloud providers to instantiate user functions in sub-millisecond windows. The design reduces server overheads while protecting cloud hosts from cross-tenant memory attacks.
