Create Istio Filters with Any Programming Language

This talk explores how to create Istio/Envoy filters using WebAssembly (Wasm) with virtually any programming language, including interpreted languages like JavaScript and PHP. The presenters demonstrate how to extend Istio's functionality beyond compiled languages like Go and Rust, enabling developers to leverage existing language skills. They cover the process, tools, and limitations of developing custom filters with Wasm and ProxyWasm.
