Web Service Architecture gives a compatible and scalable structure for web service interactions with performance, responsiveness, reliability and security to make a quality of software design. Systematic quantitative approaches have been discussed for designing and developing software systems that meet performance objectives. Many companies have successfully applied these techniques in different applications to achieve better performance in terms of financial, customer satisfaction, and other benefits. This paper describes the architecture, design, implementation, integration testing, performance and maintenance of new applications. The most successful best practices used in world class organizations are discussed. This will help the application, component, and software system designers to develop web applications and fine tune the existing methods in line with the best practices. In business process automation, many standard practices and technologies have been used to model and execute business processes. The emerging technology is web applications technology which provides a great flexibility for development of interoperable environment services. In this paper we propose a Case study of Automatic Gas Booking system, a business process development strategy and best practices used in development of software components used in web applications. The classification of QWS dataset with 2507 records, service invocations, integration and security for web applications have been discussed.

Web Services can be invoked from anywhere through internet without having enough knowledge about the implementation details. In some cases, single service cannot accomplish user needs. One or more services must be composed which together satisfy the user needs. Therefore, security is the most important concern not only at single service level but also at composition level. Several attacks are possible on SOAP messages communicated among Web Services because of their standardized interfaces. Examples of Web Service attacks are oversize payload, SOAPAction spoofing, XML injection, WS-Addressing spoofing, etc. Most of the existing works provide solution to ensure basic security features of Web Services such as confidentiality, integrity, authentication, authorization, and non-repudiation. Very few of the existing works provide solutions such as schema validation and schema hardening for attacks on Web Services. But these solutions do not address and provide attack specific solutions for SOAP messages communicated between Web Service. Hence, it is proposed to provide solutions for two of the prevailing Web Service attacks. Since new types of Web Service attacks are evolving over time, the proposed security solutions are implemented as APIs that are pluggable in any server where the Web Service is deployed.
 

Web Service (WS) plays an important role in today's word to provide effective services for humans and these web services are built with the standard of SOAP, WSDL & UDDI. This technology enables various service providers to register and service sender their intelligent agent based privacy preserving modelservices to utilize the service over the internet through pre established networks. Also accessing these services need to be secured and protected from various types of attacks in the network environment. Exchanging data between two applications on a secure channel is a challenging issue in today communication world. Traditional security mechanism such as secured socket layer (SSL), Transport Layer Security (TLS) and Internet Protocol Security (IP Sec) is able to resolve this problem partially, hence this research paper proposes the privacy preserving named as HTTPI to secure the communication more efficiently. This HTTPI protocol satisfies the QoS requirements, such as authentication, authorization, integrity and confidentiality in various levels of the OSI layers. This work also ensures the QoS that covers non functional characteristics like performance (throughput), response time, security, reliability and capacity. This proposed intelligent agent based model results in excellent throughput, good response time and increases the QoS requirements.
