Cloud computing answers some of the challenges in the ICT world, including the high investment that must be spent. This study aims to examine the adoption of the Roadmap for Cloud Computing Adoption model used for cloud computing implementation at the Indonesian Institute of Sciences. This research model uses cloud computing analysis along with each phase of ROCCA and compared with conditions in Non-Ministry Government Institutions (LPNK). The results of this study are a modification of the adoption model of ROCCA, which consists of 5 (five) stages, namely the Analysis, Design, Adoption, Migration, and Management stages.
