WebAssembly (or Wasm) gives developers a way to deploy portable code that can run at near-native speeds. As the Wasm ecosystem matures, open source tools like WasmEdge enable us to integrate Wasm with existing platforms - such as running Wasm modules alongside containers on Kubernetes.
In this Tech Talk, we’ll explore the tooling that makes this possible and show you how to create & run a Wasm module on a slim container that is subsequently deployed on Kubernetes. You'll also walk away from this talk with an understanding of when & why you may want to use WebAssembly in cloud native development, whether that be in conjunction with containers or VMs. You can find the prerequisite tooling needed to follow along with the demo below.
