Implementation of Service Oriented Architecture in Mobile Applications to Improve System Flexibility, Interoperability, and Scalability

This research aims to apply Service Oriented Architecture (SOA) to mobile applications to improve the flexibility, interoperability, and scalability of the system. SOA is an approach that enables better integration between different components in an application architecture. Mobile applications, as an integral part of everyday life, require high flexibility and adaptability to changing user needs. The research method used involves application requirements analysis, SOA architecture design, and implementation on an existing mobile application. Through the implementation of SOA, resource management and service distribution become more efficient, making it easy to add or change features without affecting the entire system. Test results show improved application performance and responsiveness, along with the ability to easily integrate services from multiple sources. In addition, the SOA architecture provides flexibility in the development and maintenance of mobile applications, accelerating the development process and minimizing the impact of changes. This research contributes to the development of mobile applications by introducing the SOA approach as an architectural foundation. The implementation of SOA in mobile applications is expected to guide developers in creating systems that are more resilient, adaptive, and easy to integrate with rapidly evolving software environments.

Boosting the visibility of services in microservice architecture

Monolithic software architectures are no longer sufficient for the highly complex software-intensive systems, which modern society depends on. Service Oriented Architecture (SOA) surpassed monolithic architecture due to its reusability, platform independency, ease of maintenance, and scalability. Recent SOA implementations made use of cloud-native architectural approaches such as microservice architecture, which has resulted in a new challenge: the discovery difficulties of services. One way to dynamically discover and route traffic to service instances is to use a service discovery tool to locate the Internet Protocol (IP) address and port number of a microservice. In the event that replicated microservice instances are found to provide the same function, it is crucial to select the right microservice that provides the best overall experience for the end-user. Parameters including success rate, efficiency, delay time, and response time play a vital role in establishing a microservice’s Quality of Service (QoS). These assessments can be performed by means of a live health-check service, or, alternatively, by making a prediction of the current state of affairs with the application of machine learning-based approaches. In this research, we evaluate the performance of several classification algorithms for estimating the quality of microservices using the QWS dataset containing traffic data of 2505 microservices. Our research also analyzed the boosting algorithms, namely Gradient Boost, XGBoost, LightGBM, and CatBoost to improve the overall performance. We utilized parameter optimization techniques, namely Grid Search, Random Search, Bayes Search, Halvin Grid Search, and Halvin Random Search to fine-tune the hyperparameters of our classifier models. Experimental results demonstrated that the CatBoost algorithm achieved the highest level of accuracy (90.42%) in predicting microservice quality.

Finding a conceptual approach to developing an architecture of general-purpose services for economic researches

The object of research is the architecture of general-purpose services for economic researches. The excessive popularity of service-oriented architecture implementations has led to consideration of the application of this approach in the production of organizations engaged in processing statistical and economic information for analytical research. This is due to the possibility of reusing services, each of which is designed to perform specific statistical functions, and the availability of design solutions for compiling these functions into a program for implementing a statistical task solution, using orchestration as a basis for dynamic service calls. The paper proposes an approach to the development of external statistical services as a set of software products for solving analytical tasks by groups of independent researchers. Since such researchers do not have sufficient financial support, the use of external statistical services will allow them to conduct an in-depth analysis of their research results. The proposed approach assumes that such a service should have its typical data storage structure with fixed types and attributes, to which the researcher imports their own data, selects a calculation execution scheme, initializes their execution, and receives results. Taking into account this storage scheme, the authors have identified the main groups of metadata necessary to describe the implementation of the statistical process. A statistical business process typically consists of a set of procedures that implement certain statistical operations and data transformations, and the provided set of metadata allows for the realization of the process goal and activity. Issues that require further in-depth research for the practical implementation of the proposed idea have been identified. The use of service-oriented architecture for building statistical processes allows for standardizing the approach by unifying the functions of individual services. The availability of possibilities for practical implementation of software products in a service-oriented architecture using a cloud environment in modern IT industry serves as a guide for further research direction.

Applications Integration in a Semi-Virtualized Environment

Enterprise application integration quickly arose as a problem for companies and solutions were proposed including point-to-point architecture, ETL (Extract, Transform and Load), EAI (Enterprise Application Integration) and ESBs (Enterprise Service Bus). With the rise of virtualization, how applications in a physical environment could interact with those that are in a virtualized environment. The objective of this paper is to study and define a Service Oriented Architecture (SOA) in a semi-virtualized environment. The authors propose an architecture which allows service integration in a semi-virtualized environment. This study uses a survey-based technique to seek which technology can be used in the considered environment. A state-of-the-art of the various IT designs and solutions enabling SOA implementation is presented. ESB technology has been retained for this study. A literary review is done on ESB to examine how it could be used in the semi-virtualized context. The findings of this study propose an architecture which allows service integration in a semi-virtualized environment. After an in-depth examination of different deployment possibilities and technical solutions proposed for this purpose, a new architecture based on the Enterprise Service Bus (ESB) is proposed for semi-virtualized context. This architecture is organized around two ESB solutions each deployed in an environment and interconnected by a communication bridge which ensures message routing between the two ESB buses. A practical deployment phase is carried out for illustration under Talend Open Studio with encouraging results. The proposed architecture is a good solution for companies whose information systems operate in a semi-virtualized environment.

Fuzzy Based Optimal QoS Constraint Services Composition in Mobile Ad Hoc Networks

In recent years, computational capability of mobile devices such as Laptops, mobile phones, PDAs, etc., are greatly improved. Implementation of SOA ("Service Oriented Architectures") in mobile ad hoc networks increases the flexibility of using mobile devices. On composing different available services to satisfy end user requirement is a critical challenge in MANETs ("Mobile Ad Hoc Network") due to dynamic topology, Resource heterogeneity, Band width constraint and highly distributed service providers. Existing composition services approaches are not suitable for MANETs due to lack of constraints consideration while choosing services. In this paper, we proposed Fuzzy based optimal QoS constrained Service Composition in MANETs. We consider Energy constraint, hop count, Response time & service throughput as QoS Constraints composing optimal services. We proposed fuzzy logic based system to provide rating to the services for optimal selection of services. We also considered that each node can provide one or more services. The service composition failure rate will be reduced by selecting optimal services in available services. The simulation result demonstrates that the proposed method outperformed than the traditional AODV in terms of average packet delay, energy constraint, throughput and turnaround time.

Overview of Service-Oriented Architecture Implementations for Calculating the Impact of External Influences on all Output Functions of an Electronic Circuit

The principles of building information systems based on service-oriented architecture are considered. The advantages of using this architectural approach, as well as a model of the component composition of the system, are described. A description of various technologies for building software using a service-oriented approach based on web services is given. The main limitations of using the CORBA technology standard for writing distributed applications are determined. The technology of building web services based on the SOAP data exchange protocol is described in the context of using the ESB service bus for the interaction of heterogeneous services in a single information system. The architectural style of microservice organization of distributed software is considered as a way to increase the granularity of the system in order to ensure the best scalability and fault tolerance of the system. Methods for constructing the mathematical support of web services for distributed schematic CAD systems for calculating the influence of external influences (changes in temperature, radiation, etc.) on all output functions of the simulated circuit are presented. Parameters of two-terminal type R, L, and C and transmission parameters of dependent current or voltage sources controlled by potential or current variables are taken as variable values of the components.

An adaptive authentication and authorization model for service oriented enterprise computing

Service oriented enterprise computing is an integration architectural style aimed to expose and consume coarse grained and fine grained modularization of business functionalities as services that are being deployed in the loosely coupled organizational environment. The web service is the implementation technology of service oriented architecture (SOA) where it is built on the existing networking and web interfacing standards as it has to use the web as a medium of communication and does not have any specialized in-built layer for security. The majority of the vendor security products in the market need specialized hardware/software components, eventually, they break the standards and principles of service oriented architecture. The traditional way of problem solving is not effective for developing security solutions for service oriented computing, as its boundaries keep expanding beyond a single organiza-tional environment due to the advent of communication and business technologies such as the Internet of Things (IoT), hyper-personalization, and edge computing. Hence, it is a mandatory entity in this digital age of enterprise computing to have a specialized authentication and authorization solution exclusively for addressing the existing security gaps in SOA in an adaptive way forward approach. In this paper, the security gaps in the existing Identity and Access Management (IDAM) solutions for service oriented enterprise computing are analyzed, and a novel intelligent security engine which is packed with extended authentication and authorization solution model for service consumption is presented. The authentication and authorization security requirements are considered as cross cutting concerns of SOA implementation and the solution is constructed as Aspect-Oriented Programming (AOP) advices, which enables the solution can be attached as a ‘plug & play’ component without changing the underlying source code of the service implementation. For Proof-of-Concept (PoC), the proposed authentication and authorization security model is tested in a large scale service oriented enterprise computing environment and the results have been analyzed statistically. It is evident from the results that the proposed security model addresses security issues comparatively better than existing security solutions.

Evaluating Service-Oriented and Microservice Architecture Patterns to Deploy eHealth Applications in Cloud Computing Environment

This article proposes a new framework for a Cloud-based eHealth platform concept focused on Cloud computing environments, since current and emerging approaches using digital clinical history increasingly demonstrate their potential in maintaining the quality of the benefits in medical care services, especially in computer-assisted clinical diagnosis within the field of infectious diseases and due to the worsening of chronic pathologies. Our objective is to evaluate and contrast the performance of the architectural patterns most commonly used for developing eHealth applications (i.e., service-oriented architecture (SOA) and microservices architecture (MSA)), using as reference the quantitative values obtained from the various performance tests and their ability to adapt to the required software attribute (i.e., versatile high-performance). Therefore, it was necessary to modify our platform to fit two architectural variants. As a follow-up to this activity, corresponding tests were performed that showed that the MSA variant functions better in terms of performance and response time compared to the SOA variant; however, it consumed significantly more bandwidth than SOA, and scalability in SOA is generally not possible or requires significant effort to be achieved. We conclude that the implementation of SOA and MSA depends on the nature and needs of organizations (e.g., performance or interoperability).

Integration of Library Data on Reference Books: with Service Oriented Architecture Implementation methods and (ESB) Enterprise Service Bus

Libraries have an important role in mastering science and technology as well as a center for information activities. Currently, the library extends its services not only in hardcopy but also in softcopy and provides faster information retrieval capabilities. Service Oriented Architecture (SOA) provides better multi-platform integration through network infrastructure. This job is to implement SOA in a Library Information System based on Glassfish Enterprice Service Bus and MySQL database. The methods for implementing library application design using SOA and ESB are built using a business process approach with several stages (M. Weske, 2006). The application of the methodology to be implemented with SOA and ESB is built using a business process approach with the following stages: The first stage, map design for integration of library requirements, the second stage is service interface design, the third stage builds relationships between services combine services that have been previously created by interaction with other services. The fourth stage is determining the logic flow that will evaluate the service logic flow that has been created with existing business processes. The fifth stage builds scenarios for shared perceptions and refining existing processes. The results show that the design has faster search capabilities that match the needs of the library.

Service-Oriented Architecture: A Review of State-of-the-Art Literature From an Organizational Perspective

Over the past two decades, the topic of service-oriented architecture (SOA) has attracted considerable attention among researchers and practitioners. Despite a lot of efforts to study it from different points of view (mostly from a technological perspective), little is done to develop our understanding of SOA from an organizational perspective. Therefore, this study aims at reviewing the literature on SOA from an organizational point of view. To this end, 65 journal papers (published between 2005 and 2020) were selected from different electronic databases for study. After a careful review of selected papers, four distinct categories of research themes were identified: SOA adoption, implementation, governance, and organizational impacts and applications. Moreover, major factors influencing SOA adoption as well as potential areas of impact of SOA in firms were determined.

And from the test can prove that 74.74% of the questions answered "Yes" are successful.

IWSN: A novel method for modeling the interaction of web services

As the most notable implementation of service-oriented architectures, web services has brought some challenging research issues, one of which is the composition. Correct interaction among web services is the prerequisite of their successful composition. In this paper, we propose a novel approach to model dynamic interactive behavior of web services, aiming to effectively take advantage of the flexibility of service composition technology and guarantee the behavior compatibility of web services and further to facilitate the application of web service composition in healthcare field. An interaction model of web services based on Kahn process network (KPN) is presented in this paper, which is a data-flow and channel-based model supporting parallel and cooperative computation. Formal behavioral semantics of this model is defined by Pi-calculus process algebra and formal properties of the proposed model are discussed. An application case is demonstrated to illustrate how the proposed model can be applied to describe services behavior and their interaction. The reachability analysis of the application case is performed based on modal -calculus. How the supporting tool, i.e. CWB-NC, can be utilized to verify the properties we anticipate is presented.

Accelerated Service Oriented Architecture Implementation of Deduplication Principle

The phrase “Web Services (WSs)” are emerging as a creative scheme for furnishing the services to various immanent devices over the World Wide Web. The hasty intensification of the WSs applications and the availability of the vast count of the Service Providers create the certainty of selecting the “efficient” Service Provider by the consumers. The scenario Deduplication and Quality-of-Service (QoS) swears out as an objective to distinguish various Service Providers (SPs). The process of selecting proficient WSs / SPs, positioning and optimization of WSs Compositions are exigent dimensions of research with momentous entailments for the fruition of the “Web of Services” revelation. The term “Semantic WSs” follows appropriate semantic descriptions of WS functionality and a medium to facilitate programmed cogitating over WS Compositions (WSCs). The persisting model of the Semantic Web Services (SWSs) deals with the intriguing emerges like wretched forecast of best WSs and gemination of services with effective SPs, which heads to Quality level degradation on the Semantic Web. To deal the above identified issues, the anticipated research is planned to construct a model to manipulative the content similarities (semantic), consumption of a mixture of WSs and its corresponding SPs. After assessing these params, all the WSs are stratified on the basis of its consumption. Ultimately, the nominated scheme, selects the best and non duplicated copy of the WSs on the basis of its rating and placed it in the WSC. The process of detecting the duplicate copy would be performed by the Cryptographic Hash value of the Services. From the experimental annotations, it is recognized that our anticipated design amends the functionality of the SWSs in terms of Processor Utilization, Accessing Time, and its Space optimizations.

NFV is an emerging key technology that overcomes many challenges facing network service providers, such as reducing the capital and the operating expenses and satisfying the growing demand for mobile services. Integrating NFV with MEC and cloud environments requires an architecture that enables efficient implementations and deployments of NFV entities. Microservices architecture is a promising implementation of service-oriented architecture with recognized advantages in terms of modularity and continuous delivery. This article envisions microservices architecture as the solution of choice for building NFV platforms that are hosted in a dynamic environment ranging from MEC to cloud environments. This article addresses the major challenges and requirements of the microservices architecture to fully-exploit the potential of its adoption in NFV. It also proposes potential solutions that alleviate these issues. The article also discusses the need for agile and modular NFV entities along with MEC to realize various applications. To this end, the article discusses explicitly a novel NFV microservices entities scheduler optimization model. The proposed scheduler aims at minimizing network delays while taking into consideration various functional and non-functional constraints. The evaluation of the simulation results demonstrates that the proposed model minimizes the computational paths' latencies and improves the performance and availability of the NFV service chains.

Usklađivanje poslovne i digitalne strategije preduzeća primenom SOA "middle-out" i servisno-baziranog pristupa

The organization's agility represents its ability to respond fast to changes by the transformation and/or optimization of business processes. In the conditions of the ever-increasing use of digital technologies, the agility of organization can be compromised if the digital strategy and IT resources are not flexible enough to adequately respond to changed business conditions. Service-Oriented Architecture (SOA) promotes better alignment of business goals and IT resources to faster respond to changes. However, given the challenges of the digital era, especially when it comes to distribution, complexity, scalability, and delivery speed, the success of the SOA initiatives increasingly depends on the choice of delivery strategy and implementation approach. The SOA middle-out delivery strategy is guided by business strategy, strategic vision and goals, with reuse of existing IT resources and focus on urgent requirements, tactical and operational goals. On the other hand, SOA evolves towards increasing agility and a simpler, service-based implementation approach that supports fast delivery. This paper, in general, discusses the ways of more efficient alignment of business and digital enterprise strategy, based on the implementation of SOA initiatives for the development of business software systems. Within the framework of the research, the significant challenges and best practices have been identified and clearly distinguished, as well as the advantages and disadvantages, which are related to the key architectural and methodological aspects of the SOA implementation using the middle-out delivery strategy and service-based approach.

Semantic interoperability and pattern classification for a service-oriented architecture in pregnancy care

Semantic interoperability represents one of the main challenges in health information systems. The development of novel interoperability models should promote the integration of heterogeneous information in the acquisition and semantic analysis of complex data patterns, which are typically used in clinical information. The purpose of this study is to develop a knowledge-based decision support system that uses ontologies for integrating data related to hypertensive disorders in pregnancy. This model allows, when dealing with new cases, inferring from a knowledge base and predicting high-risk situations that could lead to serious problems during gestation in both pregnant women and fetuses. Results demonstrate that the use of ontologies to address semantically acquired patterns from different electronic health records has the potential to significantly influence a service-oriented architecture implementation for clinical decision support systems.
