We have focused on determining the principle cloud migration processes. Our investigation have 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. 2 Assumptions and Background

– SaaS.

– PaaS.

– IaaS.

3 Cloud Migration Case studies

The three case studies SaaS, PaaS and IaaS, as well as the systems integrator

Case study shall now is looked at individually. 3.1 Saas-level Migration

3.2 Paas-level Migration

Isv:independent Software Vendors

3.3 Iaas-level Migration

3.4 Systems Integrator
