Create an Extensible Cloud Native Application with WebAssembly
Talkat Cloud Native Wasm Day North America 2021 · on Tuesday, 2021-10-12· at 14:45· Room 501 ABC + Online·
summary
Claims that embedding user code as WebAssembly inside a SaaS yields much lower latency and far higher throughput than webhooks, showing roughly an order-of-magnitude increase in executions in tests. Demonstrates loading modules from storage and running them with a Reactor multi-tenant Wasm runtime and Suborbital tooling, notes single-digit millisecond startup for small modules, and shows declarative controls to allow http and graphql while blocking internal DNS. Warns about WASI surface, multi-tenancy limits, package compatibility, and language-dependent cold starts.
