I Wasm’t Expecting This Many Apps: Scaling Without Losing Your Bytes

Liam Randall - Cosmonic / Bailey Hayes - Cosmonic

Everyone knows Wasm has a portable, secure execution model. Now it’s time to consider how server-side Wasm can empower platform engineering at scale. While Kubernetes and other tools are used for infrastructure abstraction, platform teams must also manage a vast array of common application capabilities—HTTP, blob storage, messaging, secrets—across an increasingly fragmented and regulated multi-cloud landscape. Over the years, wasmCloud has evolved into a fully modular and composable application platform.

This talk dives into how wasmCloud’s pluggable capability model allows you to centralize and standardize core services without tangling them into your application code. You’ll see two models, lifting and shifting your code to Wasm and using high-level, shared APIs defined with WIT. You’ll see live demonstrations of how platform engineers can leverage these shared APIs to update shared services for thousands of apps, mitigate compliance hurdles across diverse jurisdictions, and provide developers with simpler APIs that let them focus solely on business logic. Drawing from large-scale deployments in financial services, tech, and startups, and featuring demonstration-heavy sessions, we’ll showcase how wasmCloud transforms server-side Wasm into a golden template for platform engineering success.
