Google App Engine is cloud computing technology. It virtualizes applications across multiple servers and data centers. Other "cloud"-based platforms include offerings such as Amazon Web Services and Microsoft's Azure Services Platform. App Engine differs from services like Amazon Web Services, though, in that AWS is Infrastructure as a Service while App Engine is Platform as a Service. Google App Engine is free up to a certain level of used resources. Fees are charged for additional storage, bandwidth, or CPU cycles required by the application. |
