É possível usar as extensões de serviço
para executar seu próprio código WebAssembly (Wasm) em um
ambiente de computação totalmente sem servidor e gerenciado pelo Google. Nesta página, descrevemos a extensibilidade usando extensões de serviço.
Sobre as extensões de borda das extensões de serviço para o Cloud CDN
Você cria plug-ins usando Wasm e a ABI Proxy-Wasm.
A ABI do Proxy-Wasm oferece suporte a Rust, C++ e Go.
Os plug-ins de extensões de serviço
são executados em uma infraestrutura totalmente sem servidor gerenciada pelo Google. Eles são executados perto do plano de dados, e a otimização de latência é gerenciada.
Os plug-ins das extensões de serviço são destinados a casos de uso leves
com limites rígidos de CPU e memória. Você anexa um
plug-in de extensões de serviço a um balanceador de carga de aplicativo externo global
por uma extensão de borda.

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.
