In this talk we provide a quick overview of WebAssembly and why it is gaining popularity in the cloud. We discuss how they compare to containers, and when to use one or the other. We then explore WebAssembly support in Docker Desktop, the different runtimes it supports, their differences and their use cases. We then jump for a live demo showing how simple it is to get started. We will conclude the talk discussing the future of WebAssembly, WASI, and the component model, and how they will impact cloud workflows.
