JCLedger: A Blockchain Based Distributed Ledger for JointCloud Computing

With the development of Economic Globalization, traditional single-cloud providers can not meet the needs of the explosive, global, diverse cloud services. JointCloud aims at empowering the cooperation among multiple Cloud Service Providers (CSP) to provide cross-cloud services. Our work in this paper is mainly focused on the accounting technology for JointCloud computing and we propose the JCLedger — a blockchain based distributed ledger. A new participant CCP (Cryptocurrency Provider) is introduced into the JointCloud collaboration environment to provide the cryptocurrency transferred. We have a detailed description of JCLedger model. We further analyze the four most important mechanisms for JCLedger and provide basic perspectives for in-depth analysis. Finally, we discuss the innovations of JCLedger and our future work in this field.

Collaboration environment for JointCloud computing

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, JCCEs 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.
