Nowadays, the cloud computing ecosystem is more and more distributed and heterogeneous. Cloud service providers begin to build their services using cloud-based services offered by other service providers. This raises several issues due to integration between services and provider themselves. In this paper, we propose a practice addressing such a concern in a "Vertical Supply Chain" scenario of distributed clouds.
