Python Backend Design Patterns
Use Apache, Django and Piston.
Use REST as the protocol.
Write as little code as possible.  
Django models, forms, and admin interface.
Piston wrapppers for your resources.
I am now working on a big backend system for a real-time and history tracking web service.
I am highly experienced in Python and intend to use it with sqlalchemy (MySQL) to develop the backend.
I don't have any major experience developing robust and sustainable backend systems and I was wondering if you guys could point me out to some documentation / books about backend design patterns? I basically need to feed data to a database by querying different services (over HTML / SOAP / JSON) at realtime, and to keep history of that data.  
Thanks!
