Over the past decade, cloud services emerged as one of the mostpromising technologies in IT. Since cloud computing allows improving the qual-ity of software and, at the same time, aims at reducing costs of operating softwareand hardware, more and more software is delivered as a service in the cloud. How-ever, moving existing software applications to the cloud and making them behaveas software as a service is still a major challenge. In fact, in addition to technicalaspects, business aspects also need to be considered. The ARTIST EU project(FP7) proposes a comprehensive model-based modernization approach, coveringboth business and technical aspects, tocloudifyalready existing software. In par-ticular, ARTIST employs MDE techniques to automate the reverse engineeringand forward engineering phases in a way that modernized software truly benefitsfrom targeted cloud environments. In this paper we describe the overall ARTISTapproach and present several lessons learned.
