1 Introduction

Our work has focused on determining the principle cloud migration processes. Our investigation has shown di?erences between the cloud deployment models IaaS, PaaS and SaaS. We use an independent broker acting as a systems integrator (in contrast to the other more provider-based

migration) to broaden the view and evaluate previous results.
