In the beginning of the e-commerce era, retailers mostly adopted vertically integrated solutions to control the entire e-commerce value chain. However, they began to realize that to achieve agility, a better approach would be to focus on certain core capabilities and then create a partner ecosystem around them. From a technical point of view, this means it is advised to have a lightweight platform architecture with small core e-commerce functionality which can be extended by additional services from third party providers. In a typical e-commerce ecosystem with diverse information systems of network partners, integration and interoperability become critical factors to enable seamless coordination among the partners. Furthermore an increasing adoption of cloud computing technology could be observed resulting in more challenging integration scenarios involving cloud services. Thus, an e-commerce platform is required that suites the advanced needs for flexible and agile service integration. Therefore, this paper aims to present a reference architecture of a novel pluggable service platform for e-commerce. We investigate on currently available online shop platform solutions and integration platforms in the market. Based on the findings and motivated by literature on service-oriented design, we develop an architecture of a service-based pluggable platform for online retailers. This design is then instantiated by means of a prototype 123Inf Syst E-Bus Manage (2016) 14:469-489 DOI 10.1007 for an e-commerce returns handling scenario to demonstrate the feasibility of our architecture design.

Organizations operating in a network require strong information technology support to successfully collaborate. In a business service network, the links between partners must enable quick connect and disconnect relationships, in order to harness market opportunities. Scholars claim that information technology platforms are necessary to enhance this quick connect capability and to transform business networks into digital ecosystems. However, the state of the art in inter-organizational collaboration relies on static collaboration patterns between individual partners, and current systems are engineered without interoperability in mind. In this study, we follow a design science approach to promote the concept of platform-based collaboration. More precisely, we propose an architecture for an inter-organizational platform that facilitates the provisioning of collaboration services. Furthermore, we present a prototype in the context of e-commerce as a means of evaluating the proposed design. We conclude that the platform approach is beneficial in achieving increased flexibility in business-to-business collaboration.

Current e-commerce architectures rely on a small number of monolithic application systems. The adoption of innovative IT functionality within these architectures is a tedious and complex task. The purpose of this article is to present a design for a novel platform architecture to improve the pluggability of e-commerce services. More precisely, the pluggability of services in current architectures is described, a platform architecture is introduced, and its effect on pluggability is evaluated by means of a prototype. The enablers for this architecture are the recent innovations of web programming interfaces, delegated resource access, and client-side web application frameworks. Those technologies are common in social media and their potential in enterprise computing is revealed in this work, based on the example of a trade compliance service for cross-border retail. The results of this study suggest that the architectural design has merits as it improves the pluggability of e-commerce services. Hence, e-commerce companies should consider a paradigm shift and move from using self-contained application components to a platform-based adoption of complementary services.

Cloud services have recently gained popularity and play an increasing role in enterprise architectures. Organizations adopting cloud services expect not only improvements in flexibility and scalability, but also a means of outsourcing IT tasks. In contrast to custom or packaged applications, software as a service offerings help to reduce the technical expertise required to provide the necessary IT resources. Software quality models help organizations to assess the state of their application systems and have been subject to research for a couple of decades. However, the stakeholder of the existing quality models is mainly concerned with the internal structure of software components. With the shift towards cloud based service offerings, a different conception of quality arises. Current quality models consider resource owner and provider as a single entity. Thus, most of the quality characteristics covered in the models reflect the internal view of a software service. To address the deficiency, this paper puts forward a new quality characteristic that reflects the priorities of the service user as a distinct party, implying six different phases of service consumption. We introduce the notion of pluggability to illustrate the aspired user experience of a service and propose a preliminary measurement instrument.
