Abstract
In incremental development approaches, the integration of new services into the actual cloud application may trigger the dynamic reconfiguration of the cloud application architecture, thus changing its structure and behavior at runtime. This paper presents a model driven approach that uses the specification of how the integration of new services will change the current cloud application architecture to obtain: i) the orchestration of services, ii) skeletons of interface implementations, and iii) the operationalization of reconfiguration actions to be applied at runtime. This approach follows the DIARy-process, which defines the activities needed to reconfigure dynamically the architecture of cloud services. The feasibility of the approach is illustrated by means of a case study that uses Microsoft Azure© as a service deployment platform. WCF Workflow services are generated and deployed for orchestration, whereas XML transformation files are generated to update services’ binding configurations at runtim
