Google App Engine是一个开发、托管网络应用进程的平台，使用Google管理的数据中心。它在2008年4月发布了第一个beta版本。

Google App Engine使用了云计算技术。它跨越多个服务器和数据中心来虚拟化应用进程。 其他基于云的平台还有Amazon Web Services和微软的Azure服务平台等。

Google App Engine在用户使用一定的资源时是免费的。支付额外的费用可以获得应用进程所需的更多的存储空间、带宽或是CPU负载。

Google App Engine (often referred to as GAE or simply App Engine) is a platform as a service (PaaS) cloud computing platform for developing and hosting web applications in Google-managed data centers. Applications are sandboxed and run across multiple servers. App Engine offers automatic scaling for web applications—as the number of requests increases for an application, App Engine automatically allocates more resources for the web application to handle the additional demand.
