Framework for Dynamic Architecture Reconfiguration of Cloud Services

Cloud computing is a paradigm that is transforming the way in which organization acquire computational resources and is receiving more attention from the research community. The incremental deployment of cloud services is particularly important in agile development of cloud services, where successive cloud service increments must be integrated into existing cloud service architectures. This requires dynamic reconfiguration of software architectures, especially in cloud environments where services cannot be stopped in order to apply reconfiguration changes. A model-driven architecture reconfiguration process uses models to represent architectural and technological concepts at a high level of abstraction. Then transformations are applied on models to add the necessary detail in order to generate specific reconfiguration operations. This demands development efforts that could be alleviated not only by defining the models and transformation sequences, but also by providing tools that facilitate tasks. The aim of this research work is to propose a framework to facilitate the dynamic architectures reconfiguration of cloud services, triggered by the incremental deployment of cloud services. The aforementioned aim will be satisfied by dealing with the following sub-goals, which are:
