Service-oriented workflows are the fundamental structures in service-oriented applications and changes in the workflow could cause dramatic changes in system reliability. In several ways to re-heal workflows in execution, re-sizing service pools in the workflow is practical and easy to implement. In order to quickly adjust to workflow or environmental changes, this paper presents a dynamic service pool size configuration mechanism from the point of view of maintaining workflow reliability. An architecture-based reliability model is used to evaluate the overall reliability of a workflow with service pools and an optimal method is proposed to get the combination of service pool size aiming at minimizing the sum of service pool size subject to the workflow reliability requirement. A case study is used to explain this method and experiment results show how to change service pool size to meet the workflow reliability requirements.

This paper presents a service-oriented After-sales services system in Mechanical Engineering Industry. Typical After-sales services include status tracking services by customers, customer services, assignors and assignees. Therefore, the proposed After-sales service tracking management system work in the progress from the case study is conducted. Our system can connect with other service-related systems, such as enterprise content management repository system and business process management system. The After-sales services system is developed by consulting and visiting the machine tools manufacturers.

This paper explores the difficulties of building a service-oriented government by taking the evaluation results of public service satisfaction of Guizhou province in 2019 as an example. This paper finds that building a service-oriented government is the process of improving the quality of public service in an all-round way. With the steady improvement of the public service quality in China, the public’s expectation of the public service quality has been improved by changing from the original “yes or no” to the current “good or not”. In order to speed up the construction of service-oriented government, government departments should pay attention to the change of public demand and take the comfort, richness and transparency of public service as the key points of quality improvement.

The service-oriented approach of the university academic library is highlighted: The social institution of services is to increase quality of living, to be a tool of socializing and adaptation. The authors conclude that in the context of the education new paradigm the services make the focus of Prioksky State University Library to foster efficient library operation and coordination within the university divisions.

In order to support legacy migration to the service-oriented architecture (SOA), this paper presents a pragmatic method that derives candidates of services from procedural programs. In the SOA, every service is supposed to be a process (procedure) with (1) open interface, (2) self-containedness, and (3) coarse granularity for business. Such services are identified from the source code and its data flow diagram (DFD), by analyzing data and control dependencies among processes. Specifically, first the DFD must be obtained with reverse-engineering techniques. For each layer of the DFD, every data flow is classified into three categories. Using the data category and control among procedures, four types of dependency are categorized. Finally, six rules are applied that aggregate mutually dependent processes and extract them as a service. A case study with a liquor shop inventory control system extracts service candidates with various granularities.

Component-based approaches generalize basic object-oriented implementations by allowing large collections of objects to be grouped together and externalized in terms of public interfaces. A typical component-based system will include a large number of interacting components. Service-Oriented Architecture (SOA) organizes a system in terms of components that communicate via services. Components publish services that they implement as business processes. Consequently, a change to a single component can have a ripple effect on the service-driven system. Component reconfiguration is motivated by the need to evolve the component architecture and can take a number of forms. The authors define a dynamic architecture as one that supports changing the behavior and topology of existing components without stopping, updating, and redeploying the system. This chapter addresses the problem of dynamic reconfiguration of component-based architectures. It proposes a reification approach that represents key features of a language in data, so that a system can reason and dynamically modify aspects of it. The approach is described in terms of a new language called µLEAP and validated by implementing a simple case study.

Security is one of the largest challenges facing the development of a Service-Oriented Architecture (SOA). This is due to the fact that SOA security is the responsibility of both the service consumer and service provider. In recent years, many solutions have been implemented, such as the Web Services Security Standards, including WS-Security and WS-SecurityPolicy. However, those standards are insufficient for the promising new generations of Web 2.0 applications. In this research, we describe an Intelligent SOA Security (ISOAS) framework and introduce four of its services: Authentication and Security Service (NSS), the Authorization Service (AS), the Privacy Service (PS) and the Service of Quality of Security Service (SQoSS). Furthermore, a case study is presented to examine the behavior of the described security services inside a market SOA environment.
