Cloud Migration Process A Survey Evaluation Framework and Open Challenges
This survey addresses the need for a systematic understanding of cloud migration processes for IT professionals and researchers, though it is incremental as it synthesizes existing work.
The paper reviews and compares existing cloud migration approaches using a proposed evaluation framework to highlight their features and differences, providing an overarching view of the process for academia and practitioners.
Moving mission-oriented enterprise applications to cloud environments is a major IT strategic task and requires a systematic approach. The foci of this paper are to review and examine existing cloud migration approaches from the process models perspective. To this aim, an evaluation framework is proposed and used to analyse and compare existing approaches for highlighting their features, similarities, and key differences. The survey distills the state of the art in cloud migration research and makes a rich inventory of important activities, recommendations, techniques, and concerns that are commonly involved in the migration process in one place. This enables academia and practitioners in the cloud computing community to get an overarching view of the cloud migration process. Furthermore, the survey identifies a number challenges that have not been yet addressed by existing approaches, developing opportunities for further research endeavors.
