Explore the evolution of API Gateways and service mesh architecture in this conference talk from CNCF. Learn how to build a distributed API Gateway using service mesh technology, with a focus on extending Envoy's capabilities through WebAssembly (WASM). Discover how WASM enables dynamic runtime extension of Envoy, allowing for the integration of traditional API Gateway functions like token validation, rate limiting, and payload transformation into the service mesh layer. Gain insights into the Proxy WASM architecture, example filters, and real-world deployment scenarios. Understand the benefits of moving API Gateway functionality beyond the edge of deployments and into the service mesh itself. Delve into topics such as Envoy's dynamic configuration system, filter chains, and the relevance of API gateways in modern architectures. Explore practical demonstrations, including the "Ghettoemboy" project, and learn about WebAssemblyHub integration and using external services for rate control in distributed API Gateway implementations.
