WebAssembly (Wasm) has a misleading name, and an undeserved reputation for leaving real-world applications just out of reach. Turns out, it's come a long way in the server-side ecosystem, and it works great alongside Kubernetes! The not-so-new technology WebAssembly is a platform-agnostic bytecode that produces tiny binaries that run at near-native speed. The benefit of a platform-agnostic technology is that it works just as well outside of containers as it does inside containers, so it can be used for completely greenfield projects or integrate right alongside Kubernetes. This demo heavy talk will start with an overview of Wasm, what it's good for, and what it isn't good for. We will then dive straight into demoing the strengths of Wasm using wasmCloud, a CNCF sandbox application runtime. This demo will span multiple Kubernetes clusters in the cloud and extend outside of Kubernetes to show why this technology is perfect for solving the problems many applications face today.

As a long time Kubernetes user, it can be real confusing what all of this hype around WebAssembly (Wasm) means for the future. Join Taylor, a long-time Kubernetes community member and contributor, as he talks about Wasm; how and why it should be used; and what you can do to experiment with it. This talk will be focused on concrete strengths and weaknesses of both Kubernetes and Wasm, with a practical (and live!) demonstration of how they can be used to alongside one another. Using the CNCF sandbox project wasmCloud, Taylor will show how Wasm can be used as a complement to Kubernetes to solve many of the pain points of running applications today. To finish, Taylor will provide some practical advice on how you can try things out and get involved!
