This paper presents Deployment Factory, a modeldriven unified environment for deploying componentbased applications. While there are projects aiming to develop a unified deployment environment for component-based applications, none of them is generic enough - they do not support heterogeneous applications, they are targeted for a single component technology and/or impose modifications of the underlying technologies. The Deployment Factory targets all these issues. It is based on (i) the OMG Deployment and Configuration Specification [18], (ii) an analysis of contemporary used component technologies, and (iii) our experience from component-based development. Moreover, the paper also shows that a plain MDA approach (the one used in the OMG Deployment and Configuration specification) for building real systems is not always appropriate.
