Wasm I Right or Wasm I Wrong? a Review of the Wasm Ecosystem
Talkat KubeCon + CloudNativeCon Europe 2025 · on Wednesday, 2025-04-02· at 12:00· Level 3 | ICC Capital Suite 14-16·
summary
Wasm is already in production across CNCF projects: runtimes like Spin and WASMCloud, DB UDFs, proxy‑Wasm filters and tooling such as Zed and Inspector Gadget, with a growing need for pure Go component support. The component model reduces custom ABIs to a thin veneer, adds capability-driven security (kubectl plugin example), and is evolving toward 0.3 with native async; implementation is hard but low‑overhead. Hypervisor microVMs like Hyperlight add defense‑in‑depth when hosts must expose files or sockets.
