In the paper the advantages of the service-oriented architecture of e-government and its prospects for Ukraine are revealed. Service-oriented e-government is governed by a service-oriented architecture. Service-oriented architecture is the functionality of software as services aiming to establish compatibility in their provision. The model of service-oriented e-government architecture is divided into five layers (levels), arranged from bottom to top: operational level, semantic level, service level, process level, presentation level. The practice of service-oriented e-government in foreign countries is studies: USA, Canada, and Great Britain. These countries implement the so-called Anglo-American model of informatization of the state, which is based on: removal of redundant functions of government, delivery of public services to citizens, meeting the needs of citizens through information technology. This model promotes the development of transactions, payment for services via the Internet. Foreign experience shows that a key feature of government activities is to ensure the success of the implemented actions, as well as to control the quality and scope of services. Therefore, when developing e-government projects, the governments take their efforts to get the corresponding positive consequences in the availability of services: providing quality services to citizens and businesses; increasing revenues; easing the financial burden on federal and local governments, primarily by reducing documents and electronic services on the Internet. The trends of the model implementation in Ukraine are studies. The evolution of the issue included the Program «Electronic Ukraine», the realization of the E-Government Information System. The further steps are analyzed based on the information from the official website of the Ministry of Digital Transformation of Ukraine which provides the cases of service-oriented state (Popular services). The projects of the Ministry on Digital State digitize many services, update their legal framework, streamline the activity of state registers, and provide technical capabilities and data protection. It is concluded that service-oriented architecture of e-government is characterized by the features of its implementation based on such principles as: information-centric approach; the principle of a common platform, which focuses on creating an open information environment and common technological infrastructure for more effective collaboration of all participants and users of e-government; the principle of user orientation (all e-government activities are aimed at meeting the needs of service consumers); the principle of security and confidentiality.

Web services are playing a pivotal role in business, management, governance, and society with the dramatic development of the Internet and the Web. However, many fundamental issues are still ignored to some extent. For example, what is the unified perspective to the state-of-the-art of Web services? What is the foundation of Demand-Driven Web Services (DDWS)? This chapter addresses these fundamental issues by examining the state-of-the-art of Web services and proposing a theoretical and technological foundation for demand-driven Web services with applications. This chapter also presents an extended Service-Oriented Architecture (SOA), eSMACS SOA, and examines main players in this architecture. This chapter then classifies DDWS as government DDWS, organizational DDWS, enterprise DDWS, customer DDWS, and citizen DDWS, and looks at the corresponding Web services. Finally, this chapter examines the theoretical, technical foundations for DDWS with applications. The proposed approaches will facilitate research and development of Web services, mobile services, cloud services, and social services.

Banking Industry in India, a major section of which constitute of nationalized Banks, is facing three important challenges- to continue its contribution in rapid growth of Indian Economy, to make pace with the International Prudential Norms of Banking and Accounting Practices and to contain NPAs (Non-Performing Assets) and recover, which has reached an alarming Rs 6.0 lakhs crores. The bulk of Bank advances go to the large industries and big and established business houses, the major share of NPAs are attributed to them presently. The share of MSMEs (Micro, Small and Medium Enterprises), a priority sector of Indian economy, towards growing NPAs may need equal attention as they are in large numbers. Laying stress on strengthening legal framework to overcome this challenge not proving very effective, a service oriented architecture framework may find a solution of advance diagnosis and prevention of MSMEs turning into NPAs. This chapter proposes data mining service in cloud computing environment to Banks which can be delivered as Platform-as-a-Service through Shiny.

The services landscape is changing with the growing adoption by businesses of the Service Oriented Architecture (SOA), the migration of business solutions to the cloud, and the proliferation of smartphones and Internet-enabled handheld devices to consume services. To meet their business goals, organizations increasingly demand services, which can satisfy their functional and non-functional requirements. Service Level Agreements (SLAs) are seen as the means to guarantee the continuity in service provisioning and required levels of service. In this paper, we propose a framework for service provisioning, which aims at providing support for automated SLA negotiation and management. The Service Broker component carries out SLA negotiation with selected service-providers on behalf of service-consumers. Multi-rounds of negotiations are very often required to reach an agreement. In each round, the negotiating parties bargain on multiple SLA parameters by trying to maximize their global utility functions. The monitoring infrastructure is in charge of observing SLA compliance monitoring using measurements obtained from independent third party monitoring services.

The established global business environment is under intense pressure from Asian countries such as Korea, China, and India. This forces businesses to concentrate on their core competencies and adopt leaner management structures. The coordination of activities both within companies and with suppliers and customers has become a crucial competitive advantage. At the same time, the Internet has transformed the way in which businesses run. As the Internet becomes a cheap and effective communication channel, businesses are quick to adopt the Web for integrating their systems together and linking them with their suppliers and customers. Current enterprise computing using J2EE (Java 2 Platform, Enterprise Edition) has yielded systems in which the coupling between various components in them are too tight to be effective for ubiquitous B2B (business-to-business) and B2C (business-to-consumer) e-business over the Internet. This approach requires too much agreement and shared context between business systems from different organizations. There is a need to move away from tightly coupled, monolithic systems and toward systems of loosely coupled, dynamically bound components. The emerging technology, Web services, provides the tools to accomplish this integration, but this approach presents many new challenges and problems that must be overcome. In this article, we will discuss the current approaches in enterprise application integration (EAI) and the limitations. There is also a need for service-oriented applications, that is, Web services. Finally, the challenges in implementing Web services are outlined.

The adoption of Cloud computing in the Service Oriented Architecture (SOA) world is continuously increasing. However, as developers try to optimize their application deployment cost and performance, they may also deploy application parts redundantly on different VMs. In such heterogeneous and distributed environments, it is important to have a clear view of the system's state and its components' interrelationships. This paper aims at proposing a novel monitoring and adaptation framework for Service-based Applications (SBAs) deployed on multiple Clouds. The main functionality of this framework is the discovery of critical event patterns within monitoring event streams, leading to specific Service Level Objective (SLO) violations. Furthermore, two main meta-models are proposed for describing the SBA's components and their dependencies, and the supported adaptation actions in a specific context respectively. The proposed approach is empirically evaluated based on a real-world traffic management application.

Digital Library System

Developing and maintaining Digital Libraries requires substantial investments that are not simply a matter of technological decisions but also organizational issues. While digital libraries hold plenty of promise both now and for the future, they have been slow in taking off. Some digital libraries have either been completely abandoned or they have been put on hold indefinitely. One of the reasons for this predicament is that developers of digital libraries have approached their implementation the same traditional way of building applications, which is also akin to how structures of physical information organizations are built. Digital Libraries with their universal functionality may be even more flexible and reusable, if designed in a service-oriented manner. Such design should allow decreasing the effort of the creation of new digital libraries and the maintenance and scaling of currently existing large installations. Service-oriented architecture offers a better approach to building digital libraries, including streamlining business components, employing reusable services and connecting existing applications to communicate efficiently. The SOA is still a fairly new concept in DL systems. This chapter investigates the applicability of SOA as a fundamental architecture within the system. Its objective is to design a Service-Oriented Architecture for Digital Library System (DLS) using Web Service technology. SORADLS includes different layers which provide primitive services to the library applications built on top of the DLS. DLS techniques of personalization, alert, and caching build SORADLS as services. This architecture provides a fast, safe, convenient, and efficient service to users connected through the Internet.
