Enhancing applications with cloud services by means of aspects

摘要: In order to use remote cloud-based services, existing legacy applications need be adapted, hence partially rewritten include calls such services and take decisions on the basis of dynamic state these services. This knowledge cloud makes run smoothly, however it also more complex. this paper we propose a general software architecture, making aspect-orientation, that allows storage-related code within redefined in integrate with appropriate available several clouds. Our provided components allow integration while keeping cloud-and application-related concerns well separated, obtaining modularity. Additional provide enhanced features, as monitoring behaviour resources, connecting providers, generating replicas most accessed contents. As result, availability contents will increased, i.e., given moment unloaded service automatically selected accessed.
