    Architecture for Analysis of Streaming Data

    Full text link
    While several attempts have been made to construct a scalable and flexible architecture for analysis of streaming data, no general model to tackle this task exists. Thus, our goal is to build a scalable and maintainable architecture for performing analytics on streaming data. To reach this goal, we introduce a 7-layered architecture consisting of microservices and publish-subscribe software. Our study shows that this architecture yields a good balance between scalability and maintainability due to high cohesion and low coupling of the solution, as well as asynchronous communication between the layers. This architecture can help practitioners to improve their analytic solutions. It is also of interest to academics, as it is a building block for a general architecture for processing streaming data

    e-Business challenges and directions: important themes from the first ICE-B workshop

    A three-day asynchronous, interactive workshop was held at ICE-B’10 in Piraeus, Greece in July of 2010. This event captured conference themes for e-Business challenges and directions across four subject areas: a) e-Business applications and models, b) enterprise engineering, c) mobility, d) business collaboration and e-Services, and e) technology platforms. Quality Function Deployment (QFD) methods were used to gather, organize and evaluate themes and their ratings. This paper summarizes the most important themes rated by participants: a) Since technology is becoming more economic and social in nature, more agile and context-based application develop methods are needed. b) Enterprise engineering approaches are needed to support the design of systems that can evolve with changing stakeholder needs. c) The digital native groundswell requires changes to business models, operations, and systems to support Prosumers. d) Intelligence and interoperability are needed to address Prosumer activity and their highly customized product purchases. e) Technology platforms must rapidly and correctly adapt, provide widespread offerings and scale appropriately, in the context of changing situational contexts

    Trust and reputation policy-based mechanisms for self-protection in autonomic communications

    Currently, there is an increasing tendency to migrate the management of communications and information systems onto the Web. This is making many traditional service support models obsolete. In addition, current security mechanisms are not sufficiently robust to protect each management system and/or subsystem from web-based intrusions, malware, and hacking attacks. This paper presents research challenges in autonomic management to provide self-protection mechanisms and tools by using trust and reputation concepts based on policy-based management to decentralize management decisions. This work also uses user-based reputation mechanisms to help enforce trust management in pervasive and communications services. The scope of this research is founded in social models, where the application of trust and reputation applied in communication systems helps detect potential users as well as hackers attempting to corrupt management operations and services. These so-called “cheating services” act as “attacks”, altering the performance and the security in communication systems by consumption of computing or network resources unnecessarily

    Cloud computing adoption in regional councils

    Cloud computing is becoming increasingly important in information technology as an enabler for improved productivity, efficiency and cost reduction; and is expected to offer benefits for public sector organisations. Cloud computing has the potential to improve the reliability and scalability of information technology systems, which allows organisations such as regional municipal governments to focus more on their core business and strategy. Research about the use of cloud computing in the public sector in general is limited. There is a lack of exploratory studies that provide an in-depth and holistic investigation of the factors perceived to influence the adoption of cloud computing. There are no empirical studies about the factors that are perceived to influence the adoption of cloud computing in reference to Australia. This research aimed at exploring perceptions of the potential for value creation from cloud computing in regional councils, to identify factors that are likely to influence adoption of cloud computing including factors that need to be considered when planning to adopt cloud, anticipated benefits of cloud adoption, and challenges and issues that faced cloud adoption. This research aimed to improve understandings related to the factors that influence cloud computing adoption decision making in regional municipal governments. The research employed a mixed method approach (qualitative and quantitative). In-depth interviews of Australian councils’ IT managers were conducted with the aim of providing insights into the factors that are perceived likely to influence adoption of cloud computing including factors that need to be considered when planning to adopt cloud, anticipated benefits of cloud adoption, and challenges and issues that faced cloud adoption. Survey data from 480 IT staff across 47 local government councils were collected to confirm the findings of the exploratory stage. The factors that were examined included: compatibility, complexity, cost, security concern, top management support, organisation size, government regulation, and information intensity. The findings of this research are expected to assist in making investment decisions on cloud computing adoption
