面向跨云协同计算的资源融合与优化共享研究

Cross-Cloud Collaborative Computing is a new stage of the cloud computing development. It integrates various forms of clouds with abstract method and realizes a more flexible and optimized configuration among mutiple clouds using an open-sharing cross-cloud integrated architecture. Currently,the Cross-Cloud Collaborative Computing is still confronted with many problems and challenges such as elasticity of service capability, convertibility of resource value, scalability of computing schema and ability of availablity reconfigurability. This project intends to use the cross-cloud integration and collaborative computing, and the adaptive resource optimizating schema based on the demand-respose mechanism, to build cross-cloud collaborative computing system with interoperable configuration among mutiple clouds. The research contents include the cross-cloud collaborative computing architecture that supports resource fusion and optimized sharing, the uniform modeling of resources in heterogeneous cloud platforms and cross-cloud sharing method, the adaptive resource optimizating schema based on the demand-respose mechanism and the cross-cloud interoperation arrangement and high availablility guaranteeing mechanism. This project will innovatively propose the cross-cloud seamless management mechanism under the heterogeneous cloud integrated schema, the cross-cloud sharing method based on the nested virtualization, the resource configuration and management based on the interoperable configuration among mutiple clouds, the adaptive resource optimizating schema based on the demand-respose mechanism and the high availablility guaranteeing mechanism adopting the technology of cross-cloud reconfiguration. The research results will improve the ability of cross-cloud resource fustion and sharing as well as the collaborative operation level for the next generation cloud systems.
