Lightning Talk: Lightweight Dapr Microservices In WebAssembly
Lightningat KubeCon + CloudNativeCon North America 2022 · on Tuesday, 2022-10-25· at 17:35· Grand Riverview Ballroom AB·
summary
Dapr microservices run as WebAssembly modules using the WasmEdge runtime, claiming sub‑millisecond startup and near‑native speed while keeping a secure sandbox. The build uses Rust and JavaScript functions wired to Dapr APIs, managed on Kubernetes, and tested with databases like MySQL and TiDB and ML runtimes such as TensorFlow and PyTorch. A working demo ties three Dapr microservices to a frontend and DB to provide image upload and recognition. Source and example at github.com/second-state/dapr-wasm.
