Following things will help you decide

* what is your budget - ranging from few thousands to many million you can 
find different application servers. The lower ends like JRun from Allaire 
(www.allaire.com) and the very higher ends like Dyanmo by ATG (www.atg.com). 
BEA's Weblogic is a very popular and very good app server. Recently Oracle 
announced that they are dumping there App server and will be licensing 
Orion.

* the choice of operating system , if you are a Microsoft shop than IIS is a 
obvious choice other wise UNIX. same goes for the database, in case of MS - 
SQL Server will be a good choice, on UNIX Oracle, Informix, ....

* the language, - on MS platform its mainly Active Server Pages , on UNIX 
side you have a whole range of JAVA technology.

* are you going to host on your own or take up a third party hosting 
services.

of course this is not the end, but probably will give you a way of thinking. 
There are a lots of consulting companies that do these kind of evaluation. 
One of them is Cutter ( www.cutter.com).

Hi Richard,

     Thanks for your response. In fact the application that we're developing
is a normal C/S app. Our target size of users is a mere 5000 for now but may
increase to abt 200, 000 in the next 3 years. Would you have any application
server in mind that would suffice for this amount of transaction?



Regards,
Sio Poh
