Major evolutions have took place starting with primary structure counting on initiated request via way of means of a customer to a processing facet known as the server. Such architectures had been now no longer sufficient to manage up with the quick ever-growing range of requests and want to make use of community bandwidth. Mobile sellers tried to triumph over such drawbacks however did cope up for see you later with the developing era platforms. Service Oriented Architecture (SOA) then developed to be one of the maximum a success representations of the customer-server structure with an introduced commercial enterprise price that offers reusable and loosely coupled services. SOA did now no longer meet clients and commercial enterprise expectancies because it changed into nevertheless counting on monolithic systems. Resilience, scalability, rapid software program shipping and the usage of fewer assets are incredibly applicable features.

Network Management Architecture

Traditional NM (Network Management) techniques can not be applied on WSN (Wireless Sensor Network) due to its features of low computing ability, tiny memory space, and limited energy. A new NMA (Network Management Architecture) for WSN is needed. In this paper, we design a loosely coupled NMA of WSN based on SOA (Service-Oriented Architecture), and have well defined NM interfaces. Finally, we develop a SOA platform for WSN operations according to the NMA. Based on SOA platform, users can compose and use various NM Web Services by internet depending on their requirements. Heavy tasks which need a great deal of computing resources and storage are executed on the SOA platform. Thus, energy consumption and node computation can be decreased. Moreover, external applications use Web Services to integrate SOA platform for WSN. It lowers the difficulty in integrating different sensor platforms and heterogeneous devices.

The visionary promise of Service-Oriented Computing (SOC) is a world-scale network of loosely coupled services that can be assembled with little effort in agile applications that may span organizations and computing platforms. In practice, services are assembled in a Service-Oriented Architecture (SOA) that provides mechanisms and rules to specify, publish, discover and compose available services. The aim of this chapter is to present the different technologies implementing the new paradigm of SOA: Web Services, UPnP, DPWS, and service-oriented component OSGi and iPOJO. These technologies have been developed and adapted to multiple domains: application integration, pervasive computing and dynamic application integration.

Current protocols to agree to Web/Grid service usage do not have the capability to form negotiated agreements, nor do they take into account the legal requirements of the agreement process. This article presents a framework and a domain-independent negotiation protocol for creating legally binding contracts for service usage in a distributed, asynchronous service-oriented architecture. The negotiation protocol, which builds on a simple agreement protocol to form a multiround “symmetric” negotiation protocol, is based on an internationally recognized contract law convention. By basing our protocol on this convention and taking into account the limitations of an asynchronous messaging environment, we can form contracts between autonomous services across national and juridical boundaries, necessary in a loosely coupled, widely geographically distributed environment such as the Grid.

Contemporary architectural approach is for an orchestrated, agnostic, federated enterprise through the adoption of loosely-coupled open Service interfaces. The Service-Oriented Architecture (SOA) paradigm unifies dis­parate, heterogeneous technologies. It resurrects legacy technology silos with a Service ‘face-lift’ while maintaining their autonomy. Somewhat in its infancy as standards and methodologies are evaluated and adopted, the differences between theory and praxis of SOA remain to be fully de­termined, predominately due to the size and complexity of the conundrum it addresses.

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.

Server Architecture

This Distributed systems have evolved rapidly as the demand for independent design, and deployment ofsoftware applications has increased. It has emerged from the monolithic style of client-server architecture toservice-oriented architecture, and then to the trending microservices. Monolithic applications are difficult toupdate, maintain, and deploy as it makes the application code very complex to understand. To overcome the designand deployment challenges in monolithic applications, service oriented architecture has emerged as a style ofdecomposing the entire application into loosely coupled, scalable, and interoperable services. Though SOA hasbecome popular in the integration of multiple applications using the enterprise service bus, there are fewchallenges related to delivery, deployment, governance, and interoperability of services. Additionally, the servicesin SOA applications are tending towards monolithic in size with the increase in changing user requirements. Toovercome the design and maintenance challenges in SOA, microservices has emerged as a new architectural styleof designing applications with loose coupling, independent deployment, and scalability as key features.

The success of the Internet and the ongoing globalization led to a demand for new solutions to meet the requirements for ITsystems. The paradigm of service-oriented and event-driven architecture with fine grained and loosely coupled services tries to cope with those needs. Service Oriented Architecture (SOA) and Event Driven Architecture (EDA) are two acknowledged architectures for the development of business applications and information systems, which have evolved separately over the years. Today both architectures are acknowledged, but their synergy is not. There are numerous benefits of having an architecture that supports coexistence between operations and events, and composition of services based on operation invocation and event triggering. As part of our ongoing research work, we have tried to analyze in this paper, the basic design of Event based systems, issues that have to be addressed when event based approach is used for composing and coordinating web services. Then we have specified the techniques available that handle these issues, and gave a comparative study on these techniques. Finally we have attempted to sort out the unhandled/ partially handled issues that could be addressed as part of our research.

Cbd Method

Components-Based Development (CBD) and Web Services (WS) nowadays are prominent paradigms for implementing and deploying advanced distributed information systems. They have been proposed as the ways to support effective business/IT alignment and produce high quality and flexible software solutions that fulfill business goals within short time-to-market. However, current achievements in these areas at the level of methodology are much behind the technology ones. CBD methods proposed so far lack a comprehensive support for component and service concepts throughout the development process. By treating components as packages of implementation artifacts during software deployment or as larger-grained business objects during analysis and design, these methods are not well equipped for modeling loosely coupled coarse-grained components that offer business meaningful services organized in a Service-Oriented Architecture (SOA). This chapter presents an evaluation framework that highlights the extent to which a particular method is component-based and service-oriented. The CBD method sample is selected and evaluated using the framework’s concepts and requirements. Based on the evaluation, the method improvements are proposed in order to provide consistent, systematic, and integrated CBD and WS methodology support throughout the lifecycle.

The Impact

The aspect-oriented programming (AOP) paradigm offers software developers with powerful modularization abstractions to help them explicitly separate design concerns at the source code level. However, the impact of AOP in the service-oriented architecture (SOA) paradigm has been dwarfed by the fact that existing AOP solutions are tightly coupled to a particular programming language, middleware system or execution platform. Clearly, this not only restricts the implementation choices available to application developers, but it also clashes with the heterogeneous and loosely coupled nature of SOA. This paper presents the Web Service Aspect Language (WSAL) that seamlessly integrates AOP and SOA concepts, thus avoiding the drawbacks of existing solutions. In WSAL, aspects themselves are freely specified, implemented and executed as loosely coupled web services. This characteristic allows WSAL aspects to be easily woven into the message flow exchanged between service consumers and service providers, in a way that is completely independent from any particular implementation technology. This paper also reports on the implementation and preliminary evaluation of a prototype aspect weaver for WSAL, which is based on an existing web intermediary technology.
