  • Model-Driven Cloud Resource Management with OCCIware
    Future Generation Computer Systems, 2019
    Co-Authors: Faiez Zalila, Stéphanie Challita, Philippe Merle
    Abstract:

    Cloud computing has emerged as the main paradigm for hosting and delivering computing resources as Services over Internet. It provides a delivery Model for computing resources at infrastructure, platform, and software levels. However, there is a plethora of Cloud providers offering different resource management interfaces. Due to this diversity, the consumption, provisioning, management, and supervision of Cloud resources are subjected to four key issues, i.e., heterogeneity, interoperability, integration, and portability. To cope with these issues, Open Cloud Computing Interface (OCCI) is proposed as a community-based and open recommendation standard for managing any kind of Cloud resources. Currently, only runtime implementations exist for OCCI, and each one targets a specific Cloud Service Model such as Infrastructure as a Service (IaaS), Platform as a Service (PaaS), or Software as a Service (SaaS). Thus, OCCI lacks an approach to Model and execute different OCCI artifacts. Our approach provides a generic Modeling framework coupled with a generic runtime implementation. In this article, we propose the OCCIware approach, which represents the first approach to design, validate, generate, implement, deploy, execute, and supervise everything as a Service with OCCI. This approach provides OCCIware Studio, the first Model-driven tool chain for OCCI. It is built around OCCIware MetaModel, which defines the static semantics for the OCCI standard in Ecore and OCL. In addition, it proposes OCCIware Runtime, the first generic OCCI runtime implementation targeting all the Cloud Service Models (IaaS, PaaS, and SaaS). OCCIware provides a unique and unified framework to manage OCCI artifacts and, at the same time, it represents a factory to build Cloud domain-specific Modeling frameworks where each framework targets a specific Cloud domain. OCCIware has been applied in various Cloud domains and use-cases, which validate its applicability.

  • Study on Cloud Service mode of digital libraries based on sharing alliance
    IFIP Advances in Information and Communication Technology, 2015
    Co-Authors: Xiaorong Yang, Jian Ma, Dan Wang, Lihua Jiang, Hui Xie
    Abstract:

    As a new Service Model, Cloud Services have become the growth point of the Service innovation of digital libraries. By analyzing and summarizing the Cloud Service mode of the digital libraries at home and abroad, this paper presents three-layer Cloud Service Model of digital libraries which includes data layer, automated management layer and Service layer from bottom to top. Based on this Model, this paper puts forward the union mechanism established by some libraries which joint provide intelligence research Service, knowledge push Service, reference Service and so on.

  • CCTA (1) - Study on Cloud Service Mode of Agricultural Information Institutions
    Computer and Computing Technologies in Agriculture VII, 2013
    Co-Authors: Xiaorong Yang, Dan Wang, Lihua Jiang
    Abstract:

    As a new Service mode, Cloud Services become the growth point of the Service innovation of agricultural information institutions. This paper presents three-layer Cloud Service Model of agricultural information institutions which includes infrastructure layer, automated management system layer and Service layer from bottom to top. Based on this Model, this paper studies the Cloud Service mode and construction content of agricultural information institutions from four angles of IaaS, PaaS, DaaS and SaaS. Finally, the Cloud Service mode facing internal member institutions and readers of the national science and Technology Library is designed to verify the Cloud Service Model.

  • MCC-OSGi: An OSGi-based Mobile Cloud Service Model
    2013
    Co-Authors: Nadia Houacine, Samia Bouzefrane, Dijiang Huang, Li Li
    Abstract:

    In this article, a mobile Cloud Service Model is presented, in which it offers a dynamic and efficient remote access to information Services and resources for mobile devices. Mobile Cloud computing has been evolved as a distributed Service Model, where individual mobile users are Cloud Service providers. Compared to traditional Internet-centric Cloud Service Models, the complexity of mobile Service management in a dynamic and distributed Service environment is increased dramatically. To address this challenge, we propose to establish an OSGi-based mobile Cloud Service Model ? MCC-OSGi ? that uses OSGi Bundles as the basic mobile Cloud Service building components. The proposed solution supports OSGi bundles running on both mobile devices and Cloud-side virtual machine OS platforms, and the bundles can be transferred and run on different platforms without compatibility issues. The presented solution is achieved: 1) by incorporating OSGi into Android software development platform, 2) by setting up a Remote-OSGi on the Cloud and on mobile devices, and 3) by defining three Service architecture Models. The presented solution is validated through a demonstrative application with relevant performance measurements.
