Exploring Maintainability Assurance Research for Service- and Microservice-Based Systems: Directions and Differences

To ensure sustainable software maintenance and evolution, a diverse set of activities and concepts like metrics, change impact analysis, or antipattern detection can be used. Special maintainability assurance techniques have been proposed for service- and microservice-based systems, but it is difficult to get a comprehensive overview of this publication landscape. We therefore conducted a systematic literature review (SLR) to collect and categorize maintainability assurance approaches for service-oriented architecture (SOA) and microservices. Our search strategy led to the selection of 223 primary studies from 2007 to 2018 which we categorized with a threefold taxonomy: a) architectural (SOA, microservices, both), b) methodical (method or contribution of the study), and c) thematic (maintainability assurance subfield). We discuss the distribution among these categories and present different research directions as well as exemplary studies per thematic category. The primary finding of our SLR is that, while very few approaches have been suggested for microservices so far (24 of 223, ?11%), we identified several thematic categories where existing SOA techniques could be adapted for the maintainability assurance of microservices

Service Orientation and the Smart Grid state and trends

The energy market is undergoing major changes, the most notable of which is the transition from a hierarchical closed system toward a more open one highly based on a “smart” information-rich infrastructure. This transition calls for new information and communication technologies infrastructures and standards to support it. In this paper, we review the current state of affairs and the actual technologies with respect to such transition. Additionally, we highlight the contact points between the needs of the future grid and the advantages brought by service-oriented architectures.

Management and Service-aware Networking Architectures (MANA) for Future Internet Position Paper: System Functions, Capabilities and Requirements

Future Internet (FI) research and development threads have recently been gaining momentum all over the world and as such the international race to create a new generation Internet is in full swing: GENI, Asia Future Internet, Future Internet Forum Korea, European Union Future Internet Assembly (FIA). This is a position paper identifying the research orientation with a time horizon of 10 years, together with the key challenges for the capabilities in the Management and Service-aware Networking Architectures (MANA) part of the Future Internet (FI) allowing for parallel and federated Internet(s)

An Evolution Process For Service-Oriented Systems

Evolution of service-oriented systems is quite a new research area, which becomesmore and more important as engineering challenges move from enablingservice-orientation onto the maintenance and evolution of already developedservice-oriented systems. However, the development of suitable evolution processesand methodologies is still an open research problem. The evolution processpresented in this paper has been designed to address the evolution of serviceorientedsystems, which are technically built out of a set of service compositions.The presented process comprises phases and tasks compliant with ISO 20000.The underlying model of service-oriented system consisting of business processesand corresponding service composition models has also been presented. A traceabilitymodel and tools supporting change impact analysis have also beenprovisioned for. Preliminary industrial validation indicates that the evolutionprocess should be easy to adapt by the industry

Deferred Action: Theoretical model of process architecture design for emergent business processes

E-Business modelling and ebusiness systems development assumes fixed company resources, structures, and business processes. Empirical and theoretical evidence suggests that company resources and structures are emergent rather than fixed. Planning business activity in emergent contexts requires flexible ebusiness models based on better management theories and models . This paper builds and proposes a theoretical model of ebusiness systems capable of catering for emergent factors that affect business processes. Drawing on development of theories of the ‘action and design’class the Theory of Deferred Action is invoked as the base theory for the theoretical model. A theoretical model of flexible process architecture is presented by identifying its core components and their relationships, and then illustrated with exemplar flexible process architectures capable of responding to emergent factors. Managerial implications of the model are considered and the model’s generic applicability is discussed

Service Oriented Architecture Adoption: A Systematic Review

Service Oriented Architecture (SOA) has appeared as an absorbing architectural approach that empowers the available systems to reveal their performance in the act of services without creating important changes to the systems. This approach, due to its flexibility of adoption, has been widely appreciated by the businesses. Though there are many studies that depict successful factors of SOA, a few minor cases of failure have also been reported in the literature. In spite of the availability of rich material on SOA, there is no systematic literature review on the influential aspect of SOA adoption factors. Thus, this paper presents a systematic literature review of existing studies (from 2009 to 2015) related to the SOA adoption and its success and failure. The central purpose of the study is to focus on the existing issues and share the findings with researchers. Moreover, the findings of this paper would help the IT experts in organizations focus on the most important factors highlighted in this study, so they could decide whether it is advisable to adopt SOA in their context or not

A PROPOSITION OF CRITICAL SUCCESS FACTORS INFLUENCING SOA IMPLEMENTATION IN HEALTHCARE

Service Oriented Architecture (SOA) has been proved to be a significant integration paradigm in many sectors including healthcare. The importance of the development of integrated Information Technology (IT) services and infrastructures in healthcare is enormous as medical errors that occur due the non integrated nature of healthcare systems result in the loss of human lives. The normative literature demonstrates that organizations have difficulties in getting full benefits from SOA adoption for various reasons. Thus, we suggest that the investigation of Critical Success Factors (CSFs) related to SOA implementations in healthcare is important as the understanding of these factors may help organizations to increase the benefits they get from SOA and improve SOA acceptance rate. As a result we review the literature to identify SOA CSFs in healthcare and we classify them. Then we test them through a case study in a public healthcare organization. The results stress the crucial importance of governance and culture and proposed that a new CSF called ?Communications? should be considered. In doing so, we extend the body of literature and we suggest that further research is required to better understand SOA CSFs in healthcare
