AI for Sustainable Cloud Architectures

Cloud systems provide elastic execution environments of resources that link application and infrastructure/platform components, which are both exposed to uncertainties and change. Change appears in 2 forms: the evolution of architectural components under changing requirements and the adaptation of the infrastructure running applications. Cloud architecture continuity refers to the ability of a cloud system to change its architecture and maintain the validity of the goals that determine the architecture. Goal validity implies the satisfaction of goals in adapting or evolving systems. Architecture continuity aids technical sustainability, that is, the longevity of information, systems, and infrastructure and their adequate evolution with changing conditions. In a cloud setting that requires both steady alignment with technological evolution and availability, architecture continuity directly impacts economic sustainability. We investigate change models and change rules for managing change to support cloud architecture continuity. These models and rules define transformations of architectures to maintain system goals: Evolution is about unanticipated change of structural aspects of architectures, and adaptation is about anticipated change of architecture configurations. Both are driven by quality and cost, and both represent multidimensional decision problems under uncertainty. We have applied the models and rules for adaptation and evolution in research and industry consultancy projects.

Electronic learning or e-learning is the use of technology to enable learners to learn from anywhere and anytime. The delivery involves the use of electronic devices in some way to make available learning contents. Today, e-learning has drastically changed the educational environment. The e-learning methodology is a good example of green computing. Green computing refers to the study and practice of using computing resources in an eco-friendly manner. It is the practice of using computing resources in an energy efficient and environmentally friendly manner. In order to reduce costs, education services can be provided using cloud technology. The green cloud computing solutions save energy, reduce operational costs, and reduce carbon footprints on the environment. Hence, the objective is to provide a green cloud architecture to e-learning solutions. This architecture is addressing the issues such as improving resource use and reducing power consumption.
