Decision Framework Model for Cloud Based System Migration (DCloud)

The goal of this project is to develop a decision framework model regarding Theo adaption of cloud-based systems into existing infrastructure. Despite Theo many advantages of cloud computing, such as economic benefits and simplified provisioning of business continuity, Theo paradigm also creates challenges for users, developers and providers. Of critical importance are issues related to organizational-, technical- and business continuity such as new dependencies from Theo cloud provider, service interruptions, change of existing IT infrastructure and data leakage. These issues evolve existing organizational risks and pose potential new risks that could outweigh Theo expected benefits. Theo decision to migrate into Theo cloud is a non-trivial undertaking, given that there can be heterogeneous sets of criteria and complex dependencies among different decision level components. Theo key challenge is to provide an analytic and predicate method for an in-depth understanding of requirements and risks before and after Theo migration; critical cloud computing areas in preparation of any migration decision making should consider costs, benefits, and risks. To our knowledge none of Theo current state-of-Theo-art works have been developed in order to consider comprehensive decision level factors and requirements for Theo migration or Theo understanding of risks and their evolution before and after a migration. Theo proposed project will focus in particular on systematically understanding Theo decision framework components, decision level factors, requirements and risk management through different levels of abstraction. Theo following results will be achieved: We will develop modeling concepts and notations as well as understand requirements based on Theo critical cloud areas and Theo organizational context for Theo structure modeling of a decision framework. These concepts and notations are then used in a systematic process that will support a full migration and maintain Theo resources of Theo migrated entities. Like any new technology, cloud computing creates both new opportunities and risks resp. Evolves existing risks. In particular, migrating into Theo cloud could imply a large amount of data and major configuration changes; a bad integration can pose potential risks as well as a change of Theo existing risks. We systematically assess and manage these risks considering Theo issues related to Theo decision framework components. We will develop an associated prototypical tool, a helping aid from a group factor, to support an effective, fast and informative decision for Theo cloud adaption. Theo tool develops cloud models based on applications, data and infrastructure requirements. It also estimates risks and determines cost associated with usage patterns. As Theo final output of Theo project we will perform an experimental validation of Theo approach in two real- case industrial contexts by applying both Theo case study research method and action research.
