Whether you are deploying your application on Kubernetes or not, chances are high your application sits behind a proxy. Certain proxies can do more than just route a request to an endpoint. A few years back, Envoy started supporting Wasm as a way for users to run custom filters within the proxy’s process, which lets you do… “stuff”… In this session, we’ll go over how Kuadrant leverages that extension point of nowadays proxies to support use-cases like authentication and rate limiting. We’ll then explore how much more can be done with the Wasm proxy ABI and the open source Rust SDK. With these tools, developers will be able to leverage the power of Rust & Wasm to provide their users with the best experience possible, while maintaining lean & slick deployment of their applications and keeping both their cloud costs & latency under control. By the end of this session you’ll be able to see how to leverage the Wasm Proxy ABI to bring your server-side applications to the next level.
