摘　　要：云际计算(Joint Cloud computing)是以多个云服务实体之间开放协作为基础,通过多方云资源深度融合,方便开发者通过"软件定义"方式定制云服务、创造云价值的新一代云计算模式.如何实现云服务交易是云际计算面临的重要课题.本文提出支持不同云交易参与者之间自主对等交易资源和服务的支撑环境——云际协作环境(Joint Cloud cooperation environment,JCCE),JCCE包括分布云交易、分布云社区、分布云监管以及基于区块链的分布记账系统,JCCE中与信息交换尤其是价值交换相关的支撑技术,利于打破云际协作参与方之间的信息不对称,为参与各方创造多赢机会,实现对云际计算商业模式创新的强有力支撑.论文从云服务消费者、云服务提供者、云服务代理等视角出发,分别提出了JCCE的消费服务模式、供给服务模式和磋商服务模式,便于指导交易各方高效、便捷获取JCCE价值交换支撑服务.本文以云资源交易、数据交易和定制软件服务交易等场景为对象,阐述了JCCE中有关价值交换支撑服务的运行机理.JointCloud computing is a new generation of cloud computing mode based on the cooperation among multicloud service entities. Through the deep integration of multicloud resources, it facilitates developers to customize cloud services by the method of ＂software definition＂, and to create cloud value. Achieving successful cloud service transactions is the most important challenge that JointCloud faces. This paper originally puts forward a supporting environment of cross-stakeholders＇ peer-to-peer transactions, including resources and services,named JointCloud Cooperation Environment（JCCE）. The core of JCCE architecture involves distributed cloud transaction, distributed cloud community, distributed cloud monitoring, and the blockchain-based distributed ledger system. In such primary services, the related information exchange techniques, especially value exchange techniques, are conducive to breaking the information asymmetry among the participants in JointCloud, creating win-win opportunities for each party, and forming strong support for the JointCloud computing business innovation. From the perspective of cloud service consumers, cloud service providers, and cloud service brokers,JCCE＇s consumption service mode, supply service mode, and consultation service mode are put forward to guide the transaction participants to apply the value-exchange service of JCCE efficiently and conveniently. Finally,with regard to the support service of value exchange, the operation mechanism of JCCE is expounded in different scenarios including cloud resource transaction, data transaction, and custom software service transaction.
