I'm currently doing my last year internship. My project is to develop a full BI project for a company.
I'll need to take data from several places (flat files, DB, ...) put it in a DW (that I'll create) and make ad-hoc report. I'll certainly use pentaho or jasper.
I'll have a server (physical) for my DW of course. The question is, can I install the whole BI application on the same server (the ETL, reporting ...) where I put the DW?
If yes shoud I create 2 virtual server on my only physical server or it's useless?
You can install Whole BI Application on the same server. You can create several folders for each of BI Component such as BI Server, ETL, Reporting, etc. You needn't create 2 virtual server.
