Cloud services might offer several benefits to small and medium companies, such as on-demand resource provisioning, pay-as-you-go, and scalability. Although there are several studies and tools to support the application migration to the cloud, the lack of guidelines to support a systematic cloud migration often leads to ad hoc migrations, which significantly increase costs and compromise the migration success. This research uses the KAOS, a goal-oriented requirement engineering technique, to devise a catalogue of goals that guide migration teams when migratingWeb applications to five widely used cloud services: relational databases, virtual machines, storage, deployment and queuing. Goals, which represent migration objectives, were identified following a systematic process based on the KAOS goal, responsibility and obstacle model. A rigorous evaluation with qualified professionals showed that the catalogue assists novice companies and professionals regarding cloud migration. In addition, the catalogue contributes to identifying critical and relevant aspects of the migration process. Small and medium companies might save a significant effort by using the catalogue as a guide when analysing the migration of applications to the cloud. |
