SOFTWARE MODERNIZATION AND CLOUDIFICATION USING THE ARTIST MIGRATION METHODOLOGY AND FRAMEWORK

Abstract. Cloud computing has leveraged new software development and provisioning approaches by changing the way computing, storage and networking resources are purchased and consumed. The variety of cloud oerings on both technical and business level has considerably advanced the development process and established new business models and value chains for applications and services. However, the modernization and cloudication of legacy software so as to be oered as a service still encounters many challenges. In this work, we present a complete methodology and a methodology instantiation framework for the eective migration of legacy software to modern cloud environments.

Nowadays, cloud computing [4] appears as one of the most popular and mature techno-logical and business environments for engineering, hosting and provisioning software applications. A continu-ously increasing set of cloud-based solutions across the cloud stack layers [11] is available to application owners and developers to tailor their applications and exploit the advanced features of this paradigm for elasticity, high availability and performance. These solutions provide many benefits to new applications but they also intro
