SummaryService Oriented Architecture (SOA) has become a mainstream approach for enterprises to integrate their disparate systems — and at the same time create a closer alignment between business processes and IT. In this paper we present an overview of how to implement a Service Oriented Architecture using open standards and open source software (OSS). In particular we will look at the prevalence of open source in SOA, and explore the use of an Enterprise Service Bus (ESB) in creating and managing an SOA deployment.

The Cost

Since the early 1980s, Open Source Software (OSS) has gained a strong interest and an increased acceptance in the software industry that has to date initiated a “paradigm shift” (O’Reilly, 2004). The Open Source paradigm has introduced wholly new means of software development and distribution, creating a significant impact on the evolution of numerous business processes. In this chapter we examine the impact of the open source paradigm in the e-Procurement evolution and identify a trend towards Open Source e-Procurement Application Frameworks (AFs) which enable the development of tailored e-Procurement Solutions. Anchored in this notion, we present an Open-Source e-Procurement AF with a two-phase generation procedure. The innovative aspect of the proposed model relates to the combination of the Model Driven Engineering (MDE) approach with the Service-Oriented Architecture (SOA) paradigm for enabling the cost-effective production of e-Procurement Solutions by facilitating integration, interoperability, easy maintenance, and management of possible changes in the European e-Procurement environment. The assessment process of the proposed AF and its resulting e-Procurement Solutions occurs in the context of G2B in the Western-Balkan European region. Our evaluation yields positive results and further enhancing opportunities for the proposed Open Source e-Procurement AF and its resulting e-Procurement Solutions.

The growing interest in business integration and interoperability of IT systems led to an increase in the importance of Service-Oriented Architecture (SOA), which provides tools for Enterprise Application Integration (EAI). In this sense, Enterprise Service Bus (ESB) provides technical capabilities for communication between IT systems. The aim of this article is to present the results of performance tests of selected ESBs of Open Source type. The basis for our performance analysis was a business case of the order realization in the Internet shop of electronics retailer. The order realization requires a collaboration of three IT systems. The business case has been implemented with the use of each selected ESBs: WSO2, Mule, and Talend. Test scenarios were defined and performance tests were conducted for each of the three selected ESBs. On the basis of the collected results it can be concluded that each service bus has its own strengths and weaknesses. Focusing on the merits it should be noted that WSO2 copes very well with files of small size, for small number of users, and also does not burden the CPU significantly. Results for Talend ESB, show that it does well with both kind of files, small and large sizes, for large number of users, but harder utilizes CPU. Research shows that it is worth to analyze the parameters of transmitted messages while selecting ESB for building integration solution. The results show that the Talend ESB may be a good choice for construction of integration solution in a business environment with a large number of users and diversified communications.

Lately, the building of Enterprise Application Integration (EAI) where different legacy-applications may interoperate between them has gained the focus of business research. In this sense, the Service Oriented Architecture (SOA), and particularly the utilization of Web services standards, has attracted the attention of several researchers and practitioners for implementing the needs of EAI. More concretely, the emergence of Enterprise Service Bus (ESB) has brought a layer for favouring the mediation, transformation, and thus, the communication between these diverse applications, services, or business processes in a decoupled way. Indeed, the ESB technology integrates a wide range of current technologies and business standards. The aim of this chapter is to offer the design and necessities of Future Business Environments comparing how open ESBs fulfils these requirements. Furthermore, this chapter compares six of the most well-known open ESBs considering the characteristics provided in the design of Future Business Environments.

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.

Many benefits from implementation of e-business solutions are related to network effects which means that there are many interconnected parties utilizing the same or compatible technologies. The large-scale adoption of e-business practices in public sectors and in small and medium enterprises (SMEs)-prevailing economic environments will be successful if appropriate support in the form of education, adequate legislative, directions, and open source applications is provided. This case study describes the adoption of e-business in public sectors and SMEs by using an integrated open source approach called e-modules. E-module is a model which has process properties, data properties, and requirements on technology. Therefore e-module presents a holistic framework for deployment of e-business solutions and such e-module structure mandates an approach which requires reengineering of business processes and adoption of strong standardization that solves interoperability issues. E-module is based on principles of service-oriented architectures with guidelines for introduction into business processes and integration with ERP systems. Such an open source approach enables the spreading of compatible software solutions across any given country, thus, increasing e-business adoption. This paper presents a methodology for defining and building e-modules.

Typical Component

Component-based approaches generalize basic object-oriented implementations by allowing large collections of objects to be grouped together and externalized in terms of public interfaces. A typical component-based system will include a large number of interacting components. Service-Oriented Architecture (SOA) organizes a system in terms of components that communicate via services. Components publish services that they implement as business processes. Consequently, a change to a single component can have a ripple effect on the service-driven system. Component reconfiguration is motivated by the need to evolve the component architecture and can take a number of forms. The authors define a dynamic architecture as one that supports changing the behavior and topology of existing components without stopping, updating, and redeploying the system. This chapter addresses the problem of dynamic reconfiguration of component-based architectures. It proposes a reification approach that represents key features of a language in data, so that a system can reason and dynamically modify aspects of it. The approach is described in terms of a new language called µLEAP and validated by implementing a simple case study.
