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.

Microservice Architecture

Service oriented architecture (SOA) has been widely used in the design of enterprise applications over the last two decades. Though SOA has become popular in the integration of multiple applications using the enterprise service bus, there are few challenges related to delivery, deployment, governance, and interoperability of services. To overcome the design and maintenance challenges in SOA, a new architecture of microservices has emerged with loose coupling, independent deployment, and scalability as its key features. With the advent of microservices, software architects have started to migrate legacy systems to microservice architecture. However, many challenges arise during the migration of SOA to microservices, including the decomposition of SOA to microservice, the testing of microservices designed using different programming languages, and the monitoring the microservices. In this paper, we aim to provide patterns for the most recurring problems highlighted in the literature i.e, the decomposition of SOA services, the size of each microservice, and the detection of anomalies in microservices. The suggested patterns are combined with our experience in the migration of SOA-based applications to the microservices architecture, and we have also used these patterns in the migration of other SOA applications. We evaluated these patterns with the help of a standard web-based application.

Client Server Architecture

In Service-Driven Computing, the client-server architecture describes the relationship of cooperating programs in a distributed application. The providers of a resource or service execute workloads submitted by service requestors. Web service, Grid, and Cloud Computing technologies are based on the client-server architecture. A true service-oriented architecture describes everything, anywhere, anytime as a service. This chapter presents the SORCER (Service-ORiented Computing EnviRonment) platform, which provides service-oriented modeling or programming or both (mogramming) environments within its operating system that runs front-end service-oriented mograms and dynamically manages corresponding federations of local and remote service providers. The architecture of SORCER is described with the focus on service-oriented mogramming, service context-awareness, and its operating system managing everything as a service type. A case study report illustrates how SORCER is used for a conceptual design of the next generation of efficient supersonic air vehicles.

The current E-government system faced the problem of system heterogeneous and government information scattered. The traditional E-government system architecture can’t properly solve the problem of information islands because of its slow response, not easy to expand. This paper put forward system architecture based on SOA-ESB, and analyzed its principle. SOA (Service-Oriented Architecture) changed function into service, then the ESB (Enterprise Service Bus) provide the intelligent management and integrated to service, at the last, realize the electronic government affairs system integration and information sharing. The structure has characteristics of loose coupling, scalability and maintainability.

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.

Present is the era of fast processing industries or organization gives more emphasis for planning of business processes. This planning may differ from industry to industry. Service oriented architecture provides extensible and simple architecture for industry problem solutions. Web services are a standardized way for developing interoperable applications. Web services use open standards and protocols like http, xml and soap. This chapter provides a role of enterprise service bus in building web services.

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.

Multi Agent

In this paper the authors present the design and software development of an E-learning system based on a multi-agent (MAS) architecture. The multi-agent architecture is established on the client-server model. The MAS architecture is combined with the Dynamic Content Manager (DCM) model of E-learning developed at Bergen University College, Norway. The authors first present the quality requirements of the system before they describe the architectural decisions taken. They then evaluate and discuss the benefits of using a multi-agent architecture. Finally, the MAS architecture is compared with a pure service-oriented architecture (SOA) to observe that a MAS architecture has a lot of the same qualities as this architecture, in addition to some new ones.
