    Get PDF
    Financial applications demand better performance and accuracy in a cloud than the traditional computing platforms. Therefore, designing financial software as a service (FSaaS) requires engineering and systematic approach. This paper has designed a financial SaaS component model and a service architecture supporting required flexibility, scalability, and allowing change in environment. This paper has proposed an integrated service-oriented architecture and a SaaS component model for financial domain that provides trequired scalability, flexibility and customisation. We have also demonstrated the design and customisation of service component interfaces to the financial simulation so that it provides automatic prediction models for investors to know accurate results in buy and sale prices. Therefore, large-scaled simulations can be achieved within a matter of seconds (13.5 seconds)

    Get PDF
    Service oriented architecture (SOA) is a platform and language-independent that guide different services to work together in order to perform business process.The benefits of using SOA such as interoperability, discoverability, loose coupling, flexibility and reliability have led previous researchers to use it as their fundamental basis in designing their software architecture framework.Previous researchers also have exploit SOA and implement it into flood management domain to manage the complex systems that are distributed across the network.However, previous works do not provide the detail process of emergency management into their flood management framework.Therefore, this study aims to propose a conceptual SOA framework for an integrated flood management (IFM) in order to increase the effectiveness and efficiency of managing flood.Furthermore the feasibility of using SOA and the required process of flood management in order to construct the conceptual framework are being investigated by means of a comparative study.In addition, this study also suggests the Service oriented architecture Modeling Language (SoaML) as a technique to model the services for anIFM

    Norms, organisations and semantic web services: The ALIVE approach

    Get PDF
    ALIVE is an EU FP7 STREP whose goal is the convergence of organisational and normative modelling with and service-oriented architectures (SOAs) using model-driven software engineering. The project provides a framework for designing and implementing systems, taking into account organisational, coordination and service perspectives. A key project aspect is the integration of normative systems with live SOAs, through the distributed monitoring of normative state. Here we give a brief overview of the project, explore of the domain from a service context, outline the architecture under construction and sketch the use-cases that illustrate and inform the project.Peer ReviewedPostprint (published version

    A Service-Oriented Approach for Network-Centric Data Integration and Its Application to Maritime Surveillance

    Get PDF
    Maritime-surveillance operators still demand for an integrated maritime picture better supporting international coordination for their operations, as looked for in the European area. In this area, many data-integration efforts have been interpreted in the past as the problem of designing, building and maintaining huge centralized repositories. Current research activities are instead leveraging service-oriented principles to achieve more flexible and network-centric solutions to systems and data integration. In this direction, this article reports on the design of a SOA platform, the Service and Application Integration (SAI) system, targeting novel approaches for legacy data and systems integration in the maritime surveillance domain. We have developed a proof-of-concept of the main system capabilities to assess feasibility of our approach and to evaluate how the SAI middleware architecture can fit application requirements for dynamic data search, aggregation and delivery in the distributed maritime domain

    Designing community care systems with AUML

    Get PDF
    This paper describes an approach to developing an appropriate agent environment appropriate for use in community care applications. Key to its success is that software designers collaborate with environment builders to provide the levels of cooperation and support required within an integrated agent–oriented community system. Agent-oriented Unified Modeling Language (AUML) is a practical approach to the analysis, design, implementation and management of such an agent-based system, whilst providing the power and expressiveness necessary to support the specification, design and organization of a health care service. The background of an agent-based community care application to support the elderly is described. Our approach to building agent–oriented software development solutions emphasizes the importance of AUML as a fundamental initial step in producing more general agent–based architectures. This approach aims to present an effective methodology for an agent software development process using a service oriented approach, by addressing the agent decomposition, abstraction, and organization characteristics, whilst reducing its complexity by exploiting AUML’s productivity potential. </p

    UML-SOA-Sec and Saleem's MDS Services Composition Framework for Secure Business Process Modelling of Services Oriented Applications

    Get PDF
    In Service Oriented Architecture (SOA) environment, a software application is a composition of services, which are scattered across enterprises and architectures. Security plays a vital role during the design, development and operation of SOA applications. However, analysis of today's software development approaches reveals that the engineering of security into the system design is often neglected. Security is incorporated in an ad-hoc manner or integrated during the applications development phase or administration phase or out sourced. SOA security is cross-domain and all of the required information is not available at downstream phases. The post-hoc, low-level integration of security has a negative impact on the resulting SOA applications. General purpose modeling languages like Unified Modeling Language (UML) are used for designing the software system; however, these languages lack the knowledge of the specific domain and "security" is one of the essential domains. A Domain Specific Language (DSL), named the "UML-SOA-Sec" is proposed to facilitate the modeling of security objectives along the business process modeling of SOA applications. Furthermore, Saleem's MDS (Model Driven Security) services composition framework is proposed for the development of a secure web service composition

    Architectures v/s Microservices

    As it evolves, technology has always found a better way to build applications and improve their efficiency. New techniques have been learned by adapting old technologies and observing how markets shift towards new trends to satisfy their customers and shareholders. By taking Service Oriented Architecture (SOA) and evolving techniques in cloud computing, Web 2.0 emerged with a new pattern for designing an architecture evolved from the conventional monolithic approach known as microservice architecture (MSA). This new pattern develops an application by breaking the substantial use into a group of smaller applications, which run on their processes and communicate through an API. This style of application development is suitable for many infrastructures, especially within a cloud environment. These new patterns advanced to satisfy the concepts of domain-driven, continuous integration, and automated infrastructure more effectively. MSA has created a way to develop and deploy small scalable applications, which allows enterprise-level applications to dynamically adjust to their resources. This paper discusses what that architecture is, what makes it necessary, what factors affect best-fit architecture choices, how microservices-based architecture has evolved, and what factors are driving service-based architectures, in addition to comparing SOA and microservice. By analyzing a few popular architectures, the factors which help in choosing the architecture design will be compared with the MSA to show the benefits and challenges that may arise as an enterprise shifts their developing architecture to microservices

    Middleware Technologies for Cloud of Things - a survey

    The next wave of communication and applications rely on the new services provided by Internet of Things which is becoming an important aspect in human and machines future. The IoT services are a key solution for providing smart environments in homes, buildings and cities. In the era of a massive number of connected things and objects with a high grow rate, several challenges have been raised such as management, aggregation and storage for big produced data. In order to tackle some of these issues, cloud computing emerged to IoT as Cloud of Things (CoT) which provides virtually unlimited cloud services to enhance the large scale IoT platforms. There are several factors to be considered in design and implementation of a CoT platform. One of the most important and challenging problems is the heterogeneity of different objects. This problem can be addressed by deploying suitable "Middleware". Middleware sits between things and applications that make a reliable platform for communication among things with different interfaces, operating systems, and architectures. The main aim of this paper is to study the middleware technologies for CoT. Toward this end, we first present the main features and characteristics of middlewares. Next we study different architecture styles and service domains. Then we presents several middlewares that are suitable for CoT based platforms and lastly a list of current challenges and issues in design of CoT based middlewares is discussed.Comment: http://www.sciencedirect.com/science/article/pii/S2352864817301268, Digital Communications and Networks, Elsevier (2017
