WebAssembly on the server
summary
The talk examines running WebAssembly (WASM) on servers, showing concrete experiments and tooling: Docker can run WASM via the wasmag runtime, and runtimes like wasmer execute .wasm artifacts rather than full containers. It describes packaging a Spin (Fermion) HTTP host and the same .wasm and deploying them to EC2, Fargate and Lambda behind a load balancer, finding Lambda cold starts around 1s while EC2/Fargate are near zero, concluding WASM server-side is feasible but gaps remain in OS bindings, packaging and runtime maturity.
