需要服务器端的iOS / Android应用程序的标准架构

Are there any standard architectures employed when building iOS/Android applications that require server-side functionality?

What infrastructure is generally preferred for such applications?

Will a simple spring/hibernate web-app work?Are there any standard architectures employed w
