Living on the Edge - Using IoT Devices on Kubernetes WebAssembly Applications

Overview

Explore the integration of WebAssembly, Kubernetes, IoT, Edge computing, and Rust in this 29-minute conference talk from KubeCon + CloudNativeCon Europe 2022. Discover how Akri, an open-source project, enables IoT device discovery and representation as requestable resources for Kubernetes clusters on the Edge. Learn about the motivations behind converting Akri components to WebAssembly, the collaboration with Krustlet, and the challenges faced due to early WASI proposals. Witness a demonstration of Akri discovering demo devices and a WebAssembly Kubernetes application utilizing them. Gain insights into the simplified IoT device usage in the Wasm environment, size improvements, and future roadmap for this innovative integration.
