Service Life Cycle

A large number of concepts such as, composition, abstraction, autonomy, lose-coupling, are introduced with Service Oriented Architecture (SOA). This diversity of concept is at the same time the strength and weakness of SOA because it may affect the realization of its benefits if not well controlled. Therefore, it is necessary to adopt an appropriate model based on SOA governance. In this paper, we propose a generic SOA governance model for all service life cycle, from design Time, Run Time to change Time. This model is mainly based on the communication of each phase within a service life cycle among all stakeholders, developers and different department leaders of the organization, so as to check services concerning capability, security and strategic business alignment. This model contains 3 kinds of groups: SOA Board Team is concerned with applying enterprise governance strategy; SOA Core Team is a group of business which takes direction from the SOA Board to help implement the required services, and IT team department which oversees the implementation of SOA related activities. The Case study and its analysis show that the more flexible & efficient organization structure, and a permanent supervisor of the service’s operations and organization goals can be obtained by using our proposed model.

Dynamic Services

Service Oriented Architecture (SOA) is changing the way in which software applications are designed, deployed and maintained. A service-oriented application consists of the runtime composition of autonomous services that are typically owned and controlled by different organizations. This decentralization impacts on the dependability of applications that consist of dynamic services agglomerates, and challenges their validation. Different techniques can be used or combined for the verification of dependability aspects, spanning over traditional off-line testing approaches, monitoring, and on-line testing. In this chapter we discuss issues and opportunities of SOA validation, we identify three different stages for validation along the service life-cycle model, and we overview some proposed research approaches and tools. The emphasis is on on-line testing, which to us is the most peculiar stage in the SOA validation process. Finally, we claim that on-line testing is only possible within an agreed governance framework.

This chapter sets out to introduce relevant foundations concerning evolution and adaptation of service-oriented systems. It starts by sketching the historical development of software systems from monolithic and mostly static applications to highly-dynamic, service-oriented systems. Then, it provides an overview and more thorough explanation of the various kinds of changes that may need to be faced by service-oriented systems. To understand how such changes could be addressed, the chapter introduces a reference service life-cycle model which distinguishes between evolution, viz. the manual modification of the specification and implementation of the system during design-time, and (self-)adaptation, viz. the autonomous modification of a service-oriented system during operation. Based on the discussion of the key activities prescribed by that life-cycle, the chapter elaborates on the need for agility in both adaptation and evolution of service-oriented systems.

Secure Element

NFC enabled mobile phones are equipped with SE combined with NFC infrastructure like readers and POS terminals. The actors in the NFC infrastructure are the pre requisites but not sufficient for the use of NFC payments. There has to be a secure way to download, install, personalize, upgrade and delete an application in SE without the need to go to the service provider or mobile operator stores. TSM solution provide means of managing the NFC service life cycle OTA by using built upon and emphasizes the role an importance in NFC ecosystem. Mobile device needs to have a trusted Execution environment a place where sensitive data can be stored in secure fashion. It is a piece of hardware called as SE.

Service Oriented

Companies’ IT Systems are confronted with constantly changing market conditions, new competitive threats and a growing number of legal regulations. The service-oriented architecture (SOA) paradigm provides a promising way to address these challenges at the level of a company’s IT infrastructure. These challenges, as well as the management of the newly introduced complexity and heterogeneity, are targeted by SOA Governance approaches. In recent years, a number of concrete frameworks for SOA Governance addressing these issues have been proposed. There is no holistic approach considering all proposed elements, consolidating them in order to form a universally applicable model. In this contribution, we motivate SOA Governance, investigate and compare different approaches, identify common concepts, and derive a generic model for governance of Service-oriented Architectures.

Nowadays, it becomes more and more critical and essential for the vendors in the business-related markets to tailor their products and software to meet the needs of the Small and Medium Businesses (SMB) since their market share has been enormously raised and the issues related to the Business-to-Business (B2B) environment are becoming great challenges to be considered. The semantic Service-Oriented Architecture (SOA)-based model involves Semantic Web Services to be applied in business environments in order to have a consistent framework that makes the data understandable for both humans and machines. The ultimate goal for using the authors’ proposed model is to transfer the enterprise Web into a medium through which data and applications can be automatically understood and processed. The main components of the proposed model and the vision of applying it to one of the business solutions will be illustrated in order to show how these components can work together to overcome the traditional SOA-based solutions weakness.

As Web service technologies mature in recent years, a growing number of geospatial Web services designed to interoperate spatial information over the network have emerged. Geospatial Web services are changing the way in which spatial information systems and applications are designed, developed and deployed. This chapter introduces all aspects of geospatial Web services from service-oriented architecture to service implementation. It covers the life cycle of geospatial Web services in terms of geospatial interoperable standards, including publish, discovery, invocation and orchestration. To make geospatial Web services more intelligent, semantic issues about geospatial data and services are discussed here. Furthermore, the applications of standard-compliant geospatial Web service are also reviewed.
