Questions about clustering and fail over

2006-11-30 Thread Yamagami

Hi there,

I'm trying to evaluate if Django might be fit for a project I'm going
to be working on. The main requirement is to be bulletproof in regards
to availability even in very high volume.

I assume a setup of a few web/app servers and one or more database
servers and a load balancer (software).
Caching is good if your data doesn't need to reflect real time state of
the database. The application in question will require real time access
all the time, so caching might not be used.

I understand that Django uses the share-nothing approach, but:

1. What happens when an app server crashes? What happens to the users
on it? Are they forced to log in again? is their session lost?
2. How are the sessions stored? Is it RAM? disk? DB perhaps?

Does anyone have more information in regards to the actual setup
recommended for clustered enviroments?
I've looked around but haven't found answers to these 2 questions.

Thanks, 

Harel
