  • Intercloud Architecture Framework for Heterogeneous Cloud Based Infrastructure Services Provisioning On-Demand
    2013 27th International Conference on Advanced Information Networking and Applications Workshops, 2013
    Co-Authors: Yuri Demchenko, Canh Ngo, Joan Antoni Garcia-espin, Cees De Laat, Juan Rodriguez, Luis M. Contreras, Giada Landi, Sergi Figuerola, Nicola Ciulli
    Abstract:

    This paper presents on-going research to develop the Intercloud Architecture Framework (ICAF) that addresses problems in multi-provider multi-domain heterogeneous cloud based infrastructure services and applications integration and interoperability, to allow their on-demand provisioning. The paper refers to existing standards and ongoing standardisation activity in Cloud Computing, in particular, recently published NIST Cloud Computing Reference Architecture (CCRA) and ITU-T JCA-Cloud activity. The proposed ICAF defines four complementary components addressing Intercloud integration and interoperability: multi-layer Cloud Services Model that combines commonly adopted cloud service models, such as IaaS, PaaS, SaaS, in one multilayer model with corresponding inter-layer interfaces, Intercloud Control and Management Plane that supports cloud based applications interaction, Intercloud Federation Framework, and Intercloud Operations Framework. The paper briefly describes the Service delivery and lifecycle management as an important ICAF component that provides a basis for consistent management and security of the provisioned on-demand complex cloud based services. The paper describes an implementation of the Intercloud Control and Management Plane in the GEYSERS project to allow optimal provisioning of the combined Network+IT resources in the inter-cloud environment. The proposed Architecture is intended to provide an architectural model for developing Intercloud middleware and in this way will facilitate clouds interoperability and integration.

  • the simple enterprise Architecture Framework giving alignment to it decisions
    International Conference on Conceptual Modeling, 2018
    Co-Authors: Giovanni Giachetti, Beatriz Marin, Estefania Serral
    Abstract:

    Context: Enterprise Architecture seeks to align organizational objectives with decisions associated to people, processes, information and technology. Different Frameworks have been proposed for designing an enterprise Architecture, such as TOGAF or Zachman. However, defining an enterprise Architecture following these Frameworks is not an easy task since it requires the alignment of organizational needs with technological decisions. Goal: This paper presents a methodological Framework, called Simple Enterprise Architecture (SEA), that eases the definition of an enterprise Architecture and provides concrete proof of the alignment between IT decisions and organizational needs. Method: The SEA Framework has been developed by integrating components from existing ones in order to generate a concrete process that guides analysts in the correct definition of an enterprise Architecture. Results: This Framework has been used in teaching system Architecture master courses for 5 years with positive results.

  • intercloud Architecture Framework for heterogeneous multi provider cloud based infrastructure services provisioning
    International Journal of Next-Generation Computing, 2013
    Co-Authors: Yuri Demchenko, Canh Ngo, Cees De Laat, Marc X Makkes, Rudolf Strijkers
    Abstract:

    This paper presents on-going research to develop the Intercloud Architecture Framework (ICAF) that addresses problems in multi-provider multi-domain heterogeneous cloud based infrastructure services and applications integration and interoperability. The paper refers to existing standards in Cloud Computing, in particular, recently published NIST Cloud Computing Reference Architecture (CCRA). The proposed ICAF defines four complementary components addressing Intercloud integration and interoperability: multi-layer Cloud Services Model (CSM) that combines commonly adopted cloud service models, such as IaaS, PaaS, SaaS, in one multilayer model with corresponding inter-layer interfaces including also access and delivery infrastructure layer; Intercloud Control and Management Plane (ICCMP) that supports cloud based applications interaction; Intercloud Federation Framework (ICFF), and Intercloud Operation Framework (ICOF). The paper provides general definition of the ICFF, its generic components and interfaces. The paper briey describes the architectural Framework for cloud based infrastructure services provisioned on-demand being developed in the Framework of the GEYSERS project that provides a basis for CSM and ICCMP implementation allowing optimized provisioning of computing, storage and networking resources. The proposed Architecture is intended to provide an architectural model for developing Intercloud middleware and in this way will facilitate clouds interoperability and integration.

  • Architecture Framework and Components for the Big Data Ecosystem
    Journal of System and Network Engineering, 2013
    Co-Authors: Yuri Demchenko, Canh Ngo, Peter Membrey
    Abstract:

    Big Data are becoming a new technology focus both in science and in industry and motivate technology shift to data centric Architecture and operational models. There is a vital need to define the basic information/semantic models, Architecture components and operational models that together comprise a so-called Big Data Ecosystem. This paper discusses a nature of Big Data that may originate from different scientific, industry and social activity domains and proposes improved Big Data definition that includes the following parts: Big Data properties ( also called Big Data 5V: Volume, Velocity, Variety, Value and Veracity), data models and structures, data analytics, infrastructure and security. The paper discusses paradigm change from traditional host or service based to data centric Architecture and operational models in Big Data. The Big Data Architecture Framework (BDAF) is proposed to address all aspects of the Big Data Ecosystem and includes the following components: Big Data Infrastructure, Big Data Analytics, Data structures and models, Big Data Lifecycle Management, Big Data Security. The paper analyses requirements to and provides suggestions how the mentioned above components can address the main Big Data challenges. The presented work intends to provide a consolidated view of the Big Data phenomena and related challenges to modern technologies, and initiate wide discussion.

  • Cinders: The continuous integration and delivery Architecture Framework
    Information and Software Technology, 2017
    Co-Authors: Daniel Ståhl, Jan Bosch
    Abstract:

    Context: The popular agile practices of continuous integration and delivery have become an essential part of the software development process in many companies, yet effective methods and tools to support design, description and communication of continuous integration and delivery systems are lacking. Objective: The work reported on in this paper addresses that lack by presenting Cinders — an Architecture Framework designed specifically to meet the needs of such systems, influenced both by prominent enterprise and software Architecture Frameworks as well as experiences from continuous integration and delivery modeling in industry. Method: The state of the art for systematic design and description of continuous integration and delivery systems is established through review of literature, whereupon a proposal for an Architecture Framework addressing requirements derived from continuous integration and delivery modeling experiences is proposed. This Framework is subsequently evaluated through interviews and workshops with engineers in varying roles in three independent companies. Results: Cinders, an Architecture Framework designed specifically for the purpose of describing continuous integration and delivery systems is proposed and confirmed to constitute an improvement over previous methods. This work presents software professionals with a demonstrably effective method for describing their continuous integration and delivery systems from multiple points of view and supporting multiple use-cases, including system design, communication and documentation. Conclusion: It is concluded that an Architecture Framework for the continuous integration and delivery domain has value; at the same time potential for further improvement is identified, particularly in the area of tool support for data collection as well as for manual modeling.

  • a comparative analysis of concepts for capability design used in capability driven development and the nato Architecture Framework
    Conference on Advanced Information Systems Engineering, 2017
    Co-Authors: Janis Stirna
    Abstract:

    Recently an approach for information system design and delivery according to run-time context has been developed. It uses the concept of capability to express the organization’s ability and capacity that enables it to achieve a business goal in a certain context, and hence is denoted Capability Driven Development (CDD). The concept of capability has also been used in other approaches because it facilitates business investment focus, it can be used as a baseline for business planning, and it directly leads to service specification and design. For example, several Enterprise Architecture Frameworks have included capability as a key concept for analyzing organization’s abilities to deliver desired functions. A notable contribution in this area is The NATO Architecture Framework (NAF), which aims at being a de facto standard for organizations operating in the areas of NATO. This paper analyses the possibilities of mapping the CDD concepts to NAF concepts that are relevant for capability design.
