Abstract. Companies keep trying various strategies in order to reduce the cost of their computer systems. The trend through which “everything is as a service” seems like the most effective solution used. By benefiting from the advantages of Cloud Computing, companies can minimize the cost of their systems and focus on their core businesses, by placing their IT parts into cloud providers. New companies can build their entire systems based on the clouds from the scratch. For legacy systems, however, the adaptation to the Cloud Computing paradigm remais the more effective solution. By proposing a methodology to adapt collaborative architectures to Cloud Computing, we intend to contribute to the first application of this technology in the industrial world. In order to validate the proposed approach, we have adapted our team’s collaborative system to the clouds.
