Creating a sustainable digital infrastructure: The role of service-oriented architecture

The United Nations’ goal of generating sustainable industry, innovation, and infrastructure is the point of departure for our reflective paper. The paper elaborates on the concepts of digital infrastructure, service-oriented architecture, and microservices. It emphasizes the benefits and challenges of creating a sustainable infrastructure based on a service-oriented environment, in which cloud services constitute an important part. We outline the prerequisites for obtaining a sustainable digital infrastructure based on services. Service-oriented architecture (SOA) and recently, microservice architecture, and cloud services, can provide organizations with the improved agility and flexibility essential for generating sustainability in a market focusing on digitalization. The reuse capability of SOA provides a common pool of information technology (IT) resources and qualifies as a green IT approach that impacts environmental protection. Previous research has identified IT and business alignment together with SOA governance as the most critical criteria when implementing SOA. This paper discusses these issues in-depth to explain sustainability.

Study on Service Oriented Architecture for Clinical Evaluation Using Computational Model

In the recent one and half decades the service oriented architecture (SoA) is the emerging technology and also inevitable for the web community people. The relevant applications are incorporated together through the web service component that provides bountiful Information to the people and the customers all over the world today. Here orchestration and choreography plays a vital role in SoA. Using the initial and the basic information, it is possible to predict the unforeseen schedule of the scenario through random process methodologies. In that particularly stochastic model is much appreciated for the above said. The recommendations can be obtained through the above method and provides all the necessary information’s to the customers using SoA interfaces. Normally hybrid linked applications were in the form of SoA. In the recent year of 2016 the leading journal established the role of SoA is an inevitable web services component and also acting as a aggregation in distributed systems (Traore, B.B., et al., 2016. Integrating MDA and SOA for improving telemedicine services. Telematics and Informatics, 33(3), pp.733–741). For any cross platform communication and commercial transactions can be possible via SoA modern architecture, which is emphasized in the journal published in the year 2014 (Su, X.Y., et al., 2014. A service oriented tele-health promotion information system with mobile application. Procedia Computer Science, 37, pp.274–281). The integration of Applications which has got some relevancy and homogeneity needs interoperable communications in health care systems. Decision making support can also be possible through the above said scenario which is accomplished through SoA [21]. In the research work 21 relevant papers were analyzed in deep and identified the gap about the methodology is the strenuous job. The real theme of the research work is to provide quicker information’s to the customers without making them in starvations.

The role of service-oriented architecture as a part of the business model

Digitalisation is affecting business models of many enterprises and changing the way information work is done. Service-oriented architecture SOA is one way of implementing this change, but despite its capability to model services on a business level, the enterprises are not able to link the value of the services with the related investments. This paper proposes the use of ontology as a tool to make service-oriented architecture an integrated part of the business model. This linkage enables the SOA investments to be evaluated as a part of the value delivery process of the enterprises.

An Analytical Model for Resource Characterization and Parameter Estimation for DAG-Based Jobs for Homogeneous Systems

High Performance Computing (HPC) systems demand and consume a significant amount of resources (e.g. server, storage, electrical energy) resulting in high operational costs, reduced reliability, and sometimes leading to waste of scarce natural resources. On one hand, the most important issue for these systems is achieving high performance, while on the other hand, the rapidly increasing resource costs appeal to effectively predict the resource requirements to ensure efficient services in the most optimized manner. The resource requirement prediction for a job thus becomes important for both the service providers as well as the consumers for ensuring resource management and to negotiate Service Level Agreements (SLAs), respectively, in order to help make better job allocation decisions. Moreover, the resource requirement prediction can even lead to improved scheduling performance while reducing the resource waste. This work presents an analytical model estimating the required resources for the modular job execution. The analysis identifies the number of processors required and the maximum and minimum bounds on the turnaround time and energy consumed. Simulation study reveals that the scheduling algorithms integrated with the proposed analytical model helps in improving the average throughput and the average energy consumption of the system. As the work predicts the resource requirements, it can even play an important role in Service-Oriented Architectures (SOA) like Cloud computing or Grid computing.

An Efficient WS-QoS Broker Based Architecture for Web Services Selection

Web Service selection is a key component in service-oriented computing. Service-oriented Architectures follow the find-bindexecute paradigm in which service providers register their services in public or private registries, which clients use to locate web services. The QoS based web service selection mechanisms plays an essential role in service-oriented architectures, because most of the applications want to use services that accurately meet their requirements. Currently, the UDDI catalogue supports only primitive matching mechanisms and provides no control over the quality of registered services. We propose a QoS broker based architecture for dynamic web service selection which facilitates the clients to specify the non-functional requirements like QoS along with functional requirements. The paper presents an efficient mechanism for finding the most suitable web service according to the consumer’s requirements.

Open process and open-source enterprise systems

Enterprise systems have become pervasive, especially at the high end of the market where SAP and Oracle service large organisations. There is a great deal of value in enterprise systems offered to all organisations, but many small and medium businesses (SMBs) cannot afford the excessive software costs of established ERP systems. There have been a number of alternative forms of enterprise systems developed, to include open-source software. Service-oriented architecture (SOA) allows vendors to efficiently adopt new processes within their products. Organisations (and open-source ERP systems) can use SOA in customising or improving their systems. Web 2.0 helps collaborative development of knowledge which can be invaluable in identifying better business processes. The Web 2.0 era makes innovative access to enterprise systems possible for many SMBs. This paper reviews the role of SOA and Web 2.0 in making ERP systems more open, and classifies open enterprise systems on the dimension of process. We propose that organisations should conduct knowledge development for business processes through Web 2.0 prior to implementing external to enterprise systems. Once better processes are developed, they can be implemented to improve enterprise systems.
