    Size Matters: Microservices Research and Applications

    Full text link
    In this chapter we offer an overview of microservices providing the introductory information that a reader should know before continuing reading this book. We introduce the idea of microservices and we discuss some of the current research challenges and real-life software applications where the microservice paradigm play a key role. We have identified a set of areas where both researcher and developer can propose new ideas and technical solutions.Comment: arXiv admin note: text overlap with arXiv:1706.0735

    A Classification of BPEL Extensions

    Get PDF
    The Business Process Execution Language (BPEL) has emerged as de-facto standard for business processes implementation. This language is designed to be extensible for including additional valuable features in a standardized manner. There are a number of BPEL extensions available. They are, however, neither classified nor evaluated with respect to their compliance to the BPEL standard. This article fills this gap by providing a framework for classifying BPEL extensions, a classification of existing extensions, and a guideline for designing BPEL extensions

    Issues about the Adoption of Formal Methods for Dependable Composition of Web Services

    Full text link
    Web Services provide interoperable mechanisms for describing, locating and invoking services over the Internet; composition further enables to build complex services out of simpler ones for complex B2B applications. While current studies on these topics are mostly focused - from the technical viewpoint - on standards and protocols, this paper investigates the adoption of formal methods, especially for composition. We logically classify and analyze three different (but interconnected) kinds of important issues towards this goal, namely foundations, verification and extensions. The aim of this work is to individuate the proper questions on the adoption of formal methods for dependable composition of Web Services, not necessarily to find the optimal answers. Nevertheless, we still try to propose some tentative answers based on our proposal for a composition calculus, which we hope can animate a proper discussion

    UniFlexView : a unified framework for consistent construction of BPMN and BPEL process views

    Process view technologies allow organizations to create different granularity levels of abstraction of their business processes, therefore enabling a more effective business process management, analysis, interoperation, and privacy controls. Existing research proposed view construction and abstraction techniques for block-based (ie, BPEL) and graph-based (ie, BPMN) process models. However, the existing techniques treat each type of the two types of models separately. Especially, this brings in challenges for achieving a consistent process view for a BPEL model that derives from a BPMN model. In this paper, we propose a unified framework, namely UniFlexView, for supporting automatic and consistent process view construction. With our framework, process modelers can use our proposed View Definition Language to specify their view construction requirements disregarding the types of process models. Our UniFlexView's system prototype has been developed as a proof of concept and demonstration of the usability and feasibility of our framework. © 2019 John Wiley & Sons, Ltd

    Towards Connecting Online Interfacing and Internal Core Business Processes

    Get PDF
    Nowadays, organisations tend to do more business online by enabling their business processes to interact with customers, suppliers, etc., via different online channels. On the other hand, their core business processes, such as production, engineering, etc., may still stay inside the organisation. As a consequence, this makes an organisation rely on the collaboration between these two types of business processes to conduct its business, and this collaboration brings issues like multiple instance correlation, process view, and process evolution, to the business process management (BPM) of the organisation. This paper reports our research in progress on these issues. It firstly identifies the requirements to fully support such collaboration, and then presents a framework to illustrate how the collaboration can be facilitated using latest BPM technologies. This framework provides a reference architecture to incorporating online interfacing and internal core business processes
