An overview of cloud portability

Abstract

The application cannot be moved to other cloud vendor on the same cloud service layer easily since it depends on the lower cloud services, as well as on the target vendor’s application and data structure. In general case the cloud applications are neither interoperable, nor portable. This paper overviews the cloud portability and its application on various service models. It analyzes and categorizes all aspects of cloud computing portability, puts perspective on each defined process and describes the current development stage for each perspective.
