“SOA是一种IT体系结构样式,支持将客户的业务或系统功能点封装成为可重复调用的服务进行集成,并可以随时随地的通过网络访问或调用这些服务以实现其业务需求。SOA的优势之一说起来就应该是做应用集成了,我们已经为客户做了很多基于SOA架构的应用集成项目,比如南京油运的SOA项目和邮政的物流系统的SOA项目等等。公司自己内部的应用集成也用了SOA架构。”北京华胜天成科技股份有限公司的首席信息官陈其伟说。 相似文献

首先介绍了面向服务的架构(SOA)的体系结构和有色Petri网的概念;然后,使用SOA的方法,通过对调度命令系统业务流程的梳理,提取出调度命令系统的一组服务模型,形成服务总线模式的调度命令系统的SOA架构;最后,以调用下达命令服务为例,将系统拆分为服务提供者、服务请求者和服务总线三个组件,再将服务总线组件拆分为接入访问组件、权限认证组件、服务路由组件和消息转换组件,利用有色Petri网在动态建模方面的优势,分别对其进行建模,详细说明了其内部流程.SOA架构提高了调度命令系统的灵活性和可扩展性,结合有色Petri网对系统内部结构和控制逻辑的形式化描述,这种架构方法与建模语言相结合的方法对调度命令系统的开发有一定的指导意义. 相似文献

Service-oriented system engineering (SOSE) and its applications to embedded system development 总被引:1,自引:0,他引:1

In the past few years, we witnessed a rapid progress in service-oriented computing (SOC), which represents a new computing
paradigm. SOC changes the way we develop and use software and hardware. Major enabling techniques, including service-oriented
architecture (SOA), service-oriented enterprise (SOE), service-oriented infrastructure (SOI), Web services (WS), and associated
protocols and standards are being established. This paper focuses on the system engineering issues and how these engineering
issues manifested in SOA development processes. SOSE differs from traditional system engineering because it emphasizes on
reusability, dynamic and adaptive nature, and unique model-driven approach. 相似文献

In this modern era of enterprise computing, the enterprise application integration (EAI) is a well-known industry-recognized architectural principle that is built based on loosely coupled application architecture, where service-oriented architecture (SOA) is the architectural pattern for the implementation of EAI, whose computational elements are called as “services.” Though SOA can be implemented in a wide range of technologies, the web services implementation of SOA becomes the current selective choice due to its simplicity that works on basic Internet protocols. Web service technology defines several supporting protocols and specifications such as SOAP and WSDL for communication with client and server for data interchange. A new architectural paradigm has emerged in SOA in recent years called REpresentational State Transfer (REST) that is also used to integrate loosely coupled service components, named RESTful web services, by system integration consortiums. This SOA implementation does not possess adequate security solutions within it, and its security is completely dependent on network/transport layer security that is obsolete owing to latest web technologies such as Web 2.0 and its upgraded version, Web 3.0. Vendor security products have major implementation constraints such as they need secured organizational environment and breach to SOA specifications, hence introducing new vulnerabilities. Herein, we examine the security vulnerabilities of RESTful web services in the view of popular OWASP rating methodologies and analyze the gaps in the existing security solutions. We hence propose an adaptive security solution for REST that uses public key infrastructure techniques to enhance the security architecture. The proposed security architecture is constructed as an adaptive way-forward Internet-of-Things (IoT) friendly security solution that is comprised of three cyclic parts: learn, predict and prevent. A novel security component named “intelligent security engine” is introduced which learns the possible occurrences of security threats on SOA using artificial neural networks learning algorithms, then it predicts the potential attacks on SOA based on obtained results by the developed theoretical security model, and the written algorithms as part of security solution prevent the SOA attacks. This paper is written to present one of such algorithms to prevent SOA attacks on RESTful web services along the discussion on the obtained results of the conducted proof-of-concept on the real-time SOA environment. A comparison of the proposed system with other competing solutions demonstrates its superiority. 相似文献
