Reengineering process of legacy systems for the cloud: An overview

Cloud computing has expressed the global vision of utility computing with promising trends to a new world of information and communication technology. The transformation of the already existing systems into new ones compatible with target cloud computing framework is one of the most important cloud computing issues. Reengineering and migration are the popular and efficient approaches to be deployed for the alteration of the legacy systems. The need of efficient reengineering approaches is very intensive with the rapid change in user demands and technological advances.
