Puedes usar Service Extensions para ejecutar tu propio código WebAssembly (Wasm) en un entorno de procesamiento completamente sin servidores y administrado por Google. En esta página, se describe la extensibilidad con las extensiones de servicio.
Acerca de las extensiones perimetrales de Service Extensions para Cloud CDN
Compilas complementos con Wasm y la ABI de Proxy-Wasm.
La ABI de Proxy-Wasm ofrece compatibilidad con Rust, C++ y Go.
Los complementos de extensiones de servicio se ejecutan en una infraestructura completamente sin servidores y administrada por Google. Se ejecutan cerca del plano de datos y se administra la optimización de la latencia.
Los complementos de Service Extensions están diseñados para casos de uso ligeros con límites estrictos en la CPU y la memoria. Conectas un complemento de Service Extensions a un balanceador de cargas de aplicaciones externo global a través de una extensión de borde.

This page describes\nextensibility by using Service Extensions.\n\nAbout Service Extensions edge extensions for Cloud CDN\n------------------------------------------------------\n\nYou build plugins using Wasm and the [Proxy-Wasm ABI](https://github.com/proxy-wasm).\nThe Proxy-Wasm ABI offers support for Rust, C++, and Go.\n[Service Extensions plugins](/service-extensions/docs/plugins-overview)\nrun on a fully serverless, Google-managed infrastructure. They run close to the\ndata plane, and latency optimization is managed.\nService Extensions plugins are intended for lightweight use\ncases with tight limits on CPU and memory. You attach a\nService Extensions plugin to a global external Application Load Balancer\nthrough an edge extension.\n\nFor more information, see\n[How edge extensions work](/service-extensions/docs/lb-extensions-overview#edge-extensions).\n\nCommon use cases\n----------------\n\nUse Service Extensions plugins with global external Application Load Balancers in\nthe following sample scenarios:\n\n**Custom traffic steering**\n: Manipulate request headers to influence backend service selection.\n\n**Cache optimization**\n: Influence which content is served from a Cloud CDN cache.\n\n**Exception handling**\n: Redirect clients to a custom error page for certain response classes.\n\n**Custom logging**\n: Log user-defined headers or custom data into Cloud Logging.\n\n**Header addition**\n: Create new headers relevant for your applications or specific customers.\n: Insert new headers for request.\n\n**Header manipulation**\n: Rewrite existing request headers or override client headers on their way\n to the backend.\n\n**Security**\n: Write custom security policies based on client requests and make enforcement\n decisions within your plugin.\n\nGet started\n-----------\n\n1.
