System requirements for ADempiere ERP Implementation

on
 In a production environment such a simple installation may not be sufficient, especially when there are more than a handful of concurrent users. Performance demands will require more attention to the architecture of the installation. In a production environment, it is highly recommended to separate the servers, with the Application Server and Database Server on different machines.

Technology Overview

 ADempiere can be setup with the database, server and client all running on the same machine. This setup is good only up to 100 concurrent users. In a production environment, where more than 100 concurrent users are using the system, it is highly recommended to separate the servers, with the Application Server and Database Server on different machines. This is the best architecture for better performance. Based on the estimate, I can give you the system specification on demand.
