Migrating SOA applications to cloud:a systematic mapping study

Cloud Computing has emerged as an economical option to use IT resources when needed without considerations about where they are allocated or how they are delivered. Cloud Computing expands the SOA capabilities by adding scalability, elasticity and other relevant quality attributes. In this context, many companies have started to migrate their SOA applications to Cloud environments without proper support. We conducted a systematic mapping study to gather the current knowledge about existing strategies for migrating SOA applications to cloud computing. 105 papers were identified and the results show that most of the approaches follow a semi-automated (conventional) strategy for migrating to the Cloud (93%) and that most of the reported works follow a hybrid deployment model (60%). We additionally identify several research gaps such as the need for more technology-independent solutions, a common definition for concepts and resources, tool support, and validation.
