    This presentation discusses a strategy for migrating to a service-oriented architecture. The starting point is legacy code in a procedural or object-oriented language. The result is a set of web services that can be accessed in a private or public cloud. The technique used is to cut out selected portions of code and to wrap them behind a service interface. The code itself can be left in the origin... View full abstract»

    The incessant trend where software engineers need to redesign legacy systems adopting a service-centric engineering approach brings new challenges for software architects and developers. Today, engineering and deploying software as a service requires specific Internet protocols, middleware and languages that often complicate the interoperability of software at all levels. Moreover, cloud computing... View full abstract»

  • Modeling and evaluation of mixed redundancy strategy with instant switching in cloud-based systems

    Mixed redundancy strategy is generally used in cloud-based systems, with different node switch mechanism from traditional mixed strategy. However, related researches often concentrates on traditional mixed redundancy strategy in which cold standby components is working only after all active nodes fail. So a model is developed to evaluate the reliability and performance of cloud-based degraded syst... View full abstract»

    As data continues to grow rapidly, NoSQL clusters have been increasingly adopted to address the storage and processing demands of these large amounts of data. In parallel, cloud computing is also increasingly being adopted due to its flexibility, cost efficiency and scalability. However, evaluating and modelling NoSQL clusters present many challenges. In this work, we explore these challenges by p... View full abstract»

  • Sustainability forecast for cloud migration

    Publication Year: 2015, Page(s):31 - 35
    Request permission for reuse | Click to expandAbstract | PDF file iconPDF (440 KB) | HTML iconHTML

    In this paper, a sustainability driven approach is proposed to measure the viability of cloud migration. The decision on cloud migration is based on sustainability dimensions, i.e., economic, environmental, social and technology, and risks associated with in these dimensions. We use Analytic Hierarchy Process and fuzzy scale to prioritize the sustainability dimensions based on a migration context ... View full abstract»

  • Architectural run-time models for operator-in-the-loop adaptation of cloud applications

    Building software systems by composing third-party cloud services promises many benefits. However, the increased complexity, heterogeneity, and limited observability of cloud services brings fully automatic adaption to its limits. We propose architectural run-time models as a means for combining automatic and operator-in-the-loop adaptations of cloud services. View full abstract»

    Over the last years several standards and reports have been published and released (ISO CCRA, TOSCA), where best practices with respect to Cloud based application design, development and deployment are described. Other frameworks such as ITIL or EFQM provide recommendations for identifying, planning, delivering and supporting IT services to the business through adaptation of the business models an...

    Measuring the quality of cloud computing provision from the client's point of view is important in order to ensure that the service conforms to the level specified in the service level agreement (SLA). With a view to avoid SLA violation, the main parameters should be determined in the agreement and then used to evaluate the fulfillment of the SLA terms at the client's side. Current studies in clou... View full abstract»

  • Service-oriented toolchains for software evolution

    Software evolution projects need to be supported by integrated toolchains, yet can suffer from inadequate tool interoperability. Practitioners are forced to deal with technical integration issues, instead of focusing on their projects' actual objectives. Lacking integration support, the resulting toolchains are rigid and inflexible, impeding project progress. This paper presents SENSEI, a service-... View full abstract»

  • Measuring test coverage of SoA services

    Publication Year: 2015, Page(s):59 - 66
    Request permission for reuse | Click to expandAbstract | PDF file iconPDF (295 KB) | HTML iconHTML

    One of the challenges of testing in a SoA environment is that testers do not have access to the source code of the services they are testing. Therefore they are not able to measure test coverage at the code level, as is done in conventional white-box testing. They are compelled to measure test coverage in other ways which satisfy the constraints of black-box testing. We propose some alternate mean... View full abstract»
