Cross-cloud App Splitting With WebAssembly Components - Matt Butcher, Fermyon
Tuesday June 24, 2025 11:55am - 12:35pm MDT
Bluebird Ballroom 2G
Take one single application compiled to WebAssembly and split it into pieces at deployment time. Run these pieces in different Kubernetes deployments, different clouds, or even split across edge and cloud.

This code-forward talk will show how to write an application using Wasm components and a combination of Rust and TypeScript. We'll show how to use the CNCF project Spin for developing apps, and then use Kubernetes, Helm, SpinKube, and other open source tools to deploy this application in multiple locations.

Conceptually, we'll tie this new development pattern to microservice architecture and distributed systems to show how WebAssembly's Component Model is paving the way for a new class of application.
