A Web service is a software system designed to support interoperable application-to-application interactions over the Internet. Web services are based on a set of XML standards, such as Web services description language (WSDL), simple object access protocol (SOAP) and universal description, discovery and integration (UDDI). A key role in the Web service architecture is played by UDDI registries, i.e., a structured repository of information that can be queried by clients to find the Web services that better fit their needs. Even if, at the beginning, UDDI has been mainly conceived as a public registry without specific facilities for security, today security issues are becoming more and more crucial, due to the fact that data published in UDDI registries may be highly strategic and sensitive. In this chapter, we focus on authenticity issues, by proposing a method based on Merkle hash trees, which does not require the party managing the UDDI to be trusted wrt authenticity. In the chapter, besides giving all the details of the proposed solution, we show its benefit wrt standard digital signature techniques.

Service provided by one electronic device to the other electronic device or devices is generally called as a web service. It may be a block of code that can be remotely accessed and utilized. In the present IT industry web services are playing a vital role in application development by providing a facility of using the existing modules to make up an application without coding from the scratch. This improves the productivity and reduces the overall project development cost and time. This paper provides the basic information of the components that supports the usage of web service along with the web service architecture. The components that are required for the web service architecture such as SOAP: simple object access protocol: used for establishing connection between components, UDDI (Universal Description, Discovery, and Integration):a registry that stores all the web services and WSDL: web service description language.

In recent years, the number and size of Web services on the Internet have a rapid development. Industry and academia start to study the web service. In Internet resources, if the web cannot be found, the web service will become meaningless. So for web services, large-scale managements and problems are the keys of the study of Internet service resources. This paper studies large-scale distributed web services in network resources based on SOA architecture ideas. It also designs the unified management and organization system of ideological and political education which treat the ideological and political education as the content. It proposes SN network resource service model of ideological and political education. With the development and popularization of the Internet today, the study on Internet resources of ideological and political education in this paper provides a theoretical reference for the innovation of the ideological and political education.

Web services are programs which perform some elementary business process of an application and are distributed over the Internet. These services are described, discovered and executed using standard languages WSDL, SOAP and UDDI. Proliferation of web services has resulted in intense competition between providers, which provide the same service. To survive in such a competitive environment, they need to advertise the quality of their service. Web service description language does not provide support to describe quality attributes. Recently, DAmbrogio proposed QOS model of web services based on a meta model of WSDL. In this paper, we present a platform to advertise QOS as declared by the service provider. This tool generates a WSDL file from Java code along with its quality of service attributes. It accepts Java code and a file containing quality attributes. These attributes include reliability, availability, and operation demand and operation latency. These attributes are included in WSDL file as a content of description element.

Web services have become a significant technology in the evolution of the Web and distributed computing. Web services represent a set of related standards that allow any two applications to communicate and exchange data via the Internet. The main components of these standards are the general architecture, the delivery protocol (SOAP), the description language (WSDL), and the discovery directory (UDDI).

Abstract There are many websites on the Internet in the early stage of development, its Web service performance is not strong enough, resulting in the failure to run the system and finally the system crash. Based on this situation, in order to ensure the accurate and efficient service of the Internet website, it is necessary to analyze and study the service performance of the Web. Distributed LAMP architecture studies and analyzes the performance of Web services, which can accurately discover the performance defects and problems of Web, and research a more appropriate configuration of service performance, and the final results presented are more accurate and effective. With the deepening development of the Internet application, the website has become a key window for many people’s information sources. Through the Internet website, we can not only understand the world more comprehensively, but also learn more knowledge. Therefore, building Web services with better performance is something we should consider. In this paper, the performance of the Web server was optimized and improved through the analysis and research of the load of the Web server, and the tuning test was carried out through distributed LAMP architecture by observing the Web service’s access to users, data information maintenance and monitoring, etc.

The rapid growth of the mobile devices market and the increasing requirements of mobile users augment the need to develop Web Service clients that could be deployed and run on both mobile and desktop devices. Different developers attempt to address this heterogeneity requirement and provide solutions that simplify and automate the development of device-aware services. This chapter proposes a Model-Driven Web Service oriented approach, which allows designing and automatically generating mobile and desktop-based clients that are able to invoke ubiquitously Web Services from different devices. This is further enabled via the Web Services Description Language that allows generating the required proxy classes, which support the communication with platform-specific clients. The applicability and efficiency of the approach is demonstrated via the design and development of a device-aware Web Service prototype.

UDDI registries are today the standard way of publishing information on Web services. They can be thought of as a structured repository of information that can be queried by clients to find the Web services that better fit their needs. Even if, at the beginning, UDDI has been mainly conceived as a public registry without specific facilities for security, today security issues are becoming more and more crucial, due to the fact that data published in UDDI registries may be highly strategic and sensitive. In this paper, we focus on authenticity issues by proposing a method based on Merkle Hash Trees, which does not require the party managing the UDDI to be trusted with authenticity. In the paper, besides giving all the details of the proposed solution, we show its benefit with standard digital signature techniques.
