Distributed Deployment architecture: implementation of the application of loose coupling, will Web application server and caching, database services and other modules decoupling, and physically isolated deployment, so that the level of functional modules can be extended, but also to avoid the cloud server IO scramble to bring about the performance degradation problem. Eliminate the single point of deployment: More than one login server, the back-end game area deployed more than one, all provide the same service; both are configured load balanced sharing flow, to avoid single point of failure. Game Update Service: can be based on Aliyun OSS+CDN provide static file distribution of low latency, if the game has a lot of ...

It is easy to compare the cost of cloud computing vendors, but it is not easy to compare the performance of the application. A performance comparison of the different types of database applications running in the same cloud or across different cloud computing environments will be a particularly challenging task.
