Definition Of

E-Business research and practice can be situated on following multiple levels: applications, technological issues, support and implementation (Ngai and Wat 2002). Here we consider technological components for realizing business processes and discuss their foundation architecture for technological enabling. The article provides an introduction to the terms, techniques and realization issues for eventdriven and service-oriented architectures. We begin with a definition of terms and propose a reference architecture for an event-driven service-oriented architecture (EDSOA). Possible applications in the area of E-Business and solution guidelines are considered in the second part of the article. Service-oriented Architectures (SOA) have gained momentum since their introduction in the last years. Seen as an approach to integrate heterogeneous applications within an enterprise architecture they are also used to design flexible and adaptable business processes. An SOA is designed as a distributed system architecture providing a good integration possibility of already existing application systems. Furthermore, SOA is mostly suitable for complex and large system landscapes.

Web Based System

Web Services (WS) technologies create the potential for an organization to collaborate with partners and customers by enabling its software applications to transact over the Internet. This collaboration is achieved by carefully incorporating Web Services in the organization’s software applications, resulting in comprehensive Service-Oriented Architecture (SOA) for the enterprise. This incorporation of WS-enabled applications and components in the organization’s overall enterprise architecture requires understanding of the service at three interrelated yet distinct layers: policies, activities, and standards. This chapter describes how the existing business processes of an organization are transitioned in to collaborative business processes that would result in a Collaborative Web- Based System (CWBS). The ideas presented in this chapter have been validated through an action-research carried out by the authors in a large energy supplier organization in Melbourne, Australia.

Enterprise Applications are difficult to implement and maintain because they require a monolith of code to incorporate required business processes. Service-oriented architecture is one solution, but challenges of dependency and software complexity remain. We propose Event-Driven Service-Oriented Architecture, which combines the benefits of component-based software development, event-driven architecture, and SOA.

The One

In a service-oriented architecture, business processes are executed as composition of services, which can suffer from vulnerabilities. These vulnerabilities in services and the underlying software applications put at risk computer systems in general and business processes in particular. Current vulnerability analysis approaches involve several manual tasks and, hence, are error-prone and costly. Service-oriented architectures impose additional analysis complexity as they provide much flexibility and frequent changes within orchestrated processes and services. Therefore, it is inevitable to provide tools and mechanisms that enable efficient and effective management of vulnerabilities within these complex systems. Model-based security engineering is a promising approach that can help to fill the gap between vulnerabilities on the one hand, and concrete protection mechanisms on the other. The authors present an approach that integrates model-based engineering and vulnerability analysis in order to cope with the security challenges of a service-oriented architecture.

Considering the lack of resources in health centers located in rural zones, a part of Colombian population goes affected by the quality of the health Service received. If this is added the low level socioeconomic of some rural population, it is generated a geographic vulnerability. For that reason in this work is presented a Service Oriented Architecture that has as objective support health centers with low technical resources with technology that allows a physical rehab attention independently of the localization of patient and health professional. By way of this, a distributed system it is proposed, using a dispersed communication media like the internet. It is planned to make a modeling process based on a formal tool like the Petri Nets to assure the definition of the services, assistant dispositive teleoperation and the integration and coordination of the system.

In this paper we will discuss Outsourcing is the commissioning of a third party (or a number of third parties) to manage a client organization.s IT assets, people and/ or activities to required results. Business process outsourcing (BPO) is a more comprehensive definition of the current situation within the outsourcing domain. BPO has become increasingly interesting as more and more business processes are commoditized and thus easier to be hosted by an external party. Cloud Computing has all the attributes and potential to support a global BPO environment. These attribute are: virtualization, service oriented architecture (SOA), utility based pricing and grid computing. Cloud Computing involves the movement of IT services . application, infrastructure and platform . onto the Internet and deployment models. Because of the high availability, high bandwidth and the increased use of the Internet it has become easier to access a variety of services, traditionally originating from within a company.s data center.

Service Oriented Architecture (SOA) is a framework for integrating business processes and supporting IT infrastructure as secure, standardized components-services-that can be reused and combined to address changing business priorities. Services are the building blocks of SOA and new applications can be constructed through consuming these services and orchestrating services within a business process. In SOA, services map to the business functions that are identified during business process analysis. Upon a successful implementation of SOA, the enterprise gain benefit by reducing development time, utilizing flexible and responsive application structure, and following dynamic connectivity of application logics between business partners. This paper presents SOA reference architecture blueprint as the building blocks of SOA which is services, service components and flows that together support enterprise business processes and the business goals.Keywords: Service Oriented Architecture, SOA Reference Architecture

Layanan Berorientasi Arsitektur (SOA) merupakan framework untuk mengintegrasikan proses bisnis dan mendukung infrastruktur TI secara aman, layanan komponen standar yang dapat digunakan kembali dan dikombinasikan untuk mengatasi perubahan prioritas bisnis. Layanan merupakan blok bangunan SOA, di mana aplikasi baru dapat dibangun melalui konsumsi layanan ini dan merancang layanan dalam proses bisnis. Dalam SOA, layanan dipetakan ke fungsi bisnis yang diidentifikasi selama analisis proses bisnis. Setelah keberhasilan implementasi SOA, perusahaan memperoleh keuntungan diantaranya mengurangi waktu pengembangan, memanfaatkan fleksibilitas dan struktur aplikasi responsif, dan mengikuti konektivitas dinamis dari logika aplikasi antara mitra bisnis. Paper ini menyajikan cetak biru referensi arsitektur SOA sebagai blok bangunan SOA yang merupakan komponen pelayanan jasa, dan arus yang bersama-sama mendukung proses bisnis perusahaan dan tujuan bisnis.
