Modules

Introduction

From the Google App Engine Documentation:

App Engine Modules (or just "Modules" hereafter) let developers factor large applications into logical components that can share stateful services and communicate in a secure fashion. An app that handles customer requests might include separate modules to handle other tasks, such as:

• API requests from mobile devices
• Internal, admin-like requests
• Backend processing such as billing pipelines and data analysis
• Modules can be configured to use different runtimes and to operate with different performance settings.

Modules can be configured to use different runtimes and to operate with different performance settings.

Modules

Modules have become a central piece of App Engine application architecture. Even if an application is module-less, it is converted to use a single default module. An application that makes use of more than one module can set each module to different configurations.
