Need design solution : Closed bid Auction application

Question

I am working on an online auction[closed-bid] web application.
I have to develop two modules, an administration module and actual auction module.
The Administration module should be able to manage the auction items.
The auction module runs the auction and takes the bid from the bidders for the auction items.
Administration domain:
     AuctionItem --> Category --> Specification Group --> Specifications
95'Honda --> Car --> General --> Make: Nissan
     All domain objects in the administration module are manageable units.
Auction domain:
     Bidder --> AuctionItem --> Category --> SpecificationGroup --> Specifications
Tom --> 95' Honda --> Car --> General --> Make: Nissan
Administration module will run on the intranet app server and Auction module will be on the internet app server.
How would I design this application?
Do I need to make two war files for each module and deploy them on the respective server?
Appreciate your feedbacks and suggestions.
Please let me know if more clarifications needed.
Thanks,
Mohideen.

Answer 1

I feel it is better to seperate the Admin from the application, ie two seperate war file on two seperate app server, this makes your application little more secure. provided your client is ready to invest in another server for the admin
