This study provides an overview over legislation, case law and administrative guidelines applicable to cloud computing contracts. It explains how the existing specific and/or general legal principles apply to certain key contractual issues. The study is carried out in three work packages. The first work package provides a general overview over relevant legislation, case law and administrative guidelines in relation to cloud computing contracts in 27 EU Member States and the U.S. level. Under work package 2, eight countries out of this group were selected to be further analysed during work... package 3. During this last phase, several key legal issues are subjected to an in-depth analysis. This input is further subjected to a comparative law assessment as a result of which several conclusions are presented in relation to the suitability of the current legal framework of the selected countries for cloud computing contracts.
