Extending and Customizing Istio with WebAssembly

Explore how WebAssembly (WASM) enhances Istio's capabilities in this 21-minute conference talk. Learn about the recent developments in WASM that enable dynamic configuration of L3/L4 and L7 proxies like Envoy, opening up new possibilities for customizing service meshes. Discover practical approaches to building sophisticated routing features, dynamically debugging requests, implementing application firewall use cases, and enforcing network policies using WASM - tasks that can be challenging with native Istio configurations. Witness demonstrations using the Proxy-Wasm Go SDK, showcasing the deployment of WASM modules in multi-cluster environments to highlight the ease of development, maintainability, and agility of WASM plugins in networking infrastructure.
