Introduction In this article, we will explore how to use KEDA, KEDA HTTP add-on, with Slight Containerd Shim to build a WASM serverless solution. The solution provides scale to/from zero support, reduced time for cold start, and cloud integration capabilities such as Azure blob, App Configuration, ServiceBus etc. The
