A Novel Effort Estimation Approach for Migration of SOA Applications to Microservices

Microservices architecture's popularity is rapidly growing as it eases the design of enterprise applications by allowing independent development and deployment of services. Due to this paradigm shift in software development, many existing Service Oriented Architecture (SOA) applications are being migrated to microservices. Estimating the effort required for migration is a key challenge as it helps the architects in better planning and execution of the migration process. Since the designing style and deployment environments are different for each service, existing effort estimation models in the literature are not ideal for microservice architecture. To estimate the effort required for migrating SOA application to microservices, we propose a new effort estimation model called Service Points. We define a formal model called service graph which represents the components of the service based architectures and their interactions among the services. Service graph provides the information required for the estimation process. We recast the use case points method and model it to become suitable for microservices architecture. We have updated the technical and environmental factors used for the effort estimation. The proposed approach is demonstrated by estimating the migration effort for a standard SOA based web application. The proposed model is compatible with the design principles of microservices and provides a systematic and formal way of estimating the effort. It helps software architects in better planning and execution of the migration process.

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.

Reflections on Cyber Security Automation via SOA IoT Middleware

The Covid-19 pandemic forced companies to both alter their operation and adapt their activities and services provided. Indicatively, remote working, hybrid work models and teleconferences became the new reality, leading to the exponential increase of businesses’ dependency on IT infrastructures, including internet usage and cloud computing. Moreover, the geopolitical environment affects cybersecurity and the likelihood of cyber-attacks on critical infrastructures. To address these issues, companies must update their digital infrastructure and reduce cyber vulnerabilities; this can be achieved through the use of middleware. In this article, we define the terms “middleware” and “Service Orientated Architecture” (SOA). Then, we explain how SOA can be fused with current middleware systems, using Automated Teller Machines (ATMs) as a case study. Finally, we review how a Cyber IoT Middleware uses SOA.

Pengembangan Kapasitas Mahasiswa Menuju Generasi Unggul di Era 4.0

The purpose of this community service is to face the Industrial Revolution 4.0, every individual, especially students, seeks to master the talents or skills needed to give birth to a professional workforce that can adapt to current conditions. To be able to adapt to the Industrial Revolution 4.0, a student must have qualities that machines do not have. One example is the ability to solve problems or creativity, and soft skills are very important for a student to have. The result of community service is that students are equipped with competencies such as complex problem solving, critical thinking, creativity, management, coordination with others, emotional intelligence, judgment, and decision making, service orientation, negotiation, and cognitive flexibility needed to meet future developments. In addition, students who already have expertise must continue to improve their abilities, while those who currently have skills but are no longer relevant must immediately adjust their skills to meet current market demands.

Exploring the Effectiveness of Service Decomposition in Fog Computing Architecture for the Internet of Things

The Internet of Things (IoT) aims to connect everyday physical objects to the internet. These objects will produce a significant amount of data. The traditional cloud computing architecture aims to process data in the cloud. As a result, a significant amount of data needs to be communicated to the cloud. This creates a number of challenges, such as high communication latency between the devices and the cloud, increased energy consumption of devices during frequent data upload to the cloud, high bandwidth consumption, while making the network busy by sending the data continuously, and less privacy because of less control on the transmitted data to the server. Fog computing has been proposed to counter these weaknesses. Fog computing aims to process data at the edge and substantially eliminate the necessity of sending data to the cloud. However, combining the Service Oriented Architecture (SOA) with the fog computing architecture is still an open challenge. In this paper, we propose to decompose services to create <italic xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">linked-microservices</i> (LMS). <italic xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">Linked-microservices</i> are services that run on multiple nodes but closely linked to their linked-partners. <italic xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">Linked-microservices</i> allow distributing the computation across different computing nodes in the IoT architecture. Using four different types of architectures namely cloud, fog, hybrid, and fog+cloud, we explore and demonstrate the effectiveness of service decomposition by applying four experiments to three different type of datasets. Evaluation of the four architectures shows that decomposing services into nodes reduce the data consumption over the network by 10 - 70 percent. Overall, these results indicate that the importance of decomposing services in the context of fog computing for enhancing the quality of service.

Crop protection market segmentation: relationship between buyer segments and the use of digital sales channels

Digital technologies are revolutionizing agricultural trade, enabling farm input suppliers to reach customers through multiple channels. The aim of this study was to segment farmers based on their purchasing behavior for crop protection products and to examine segment-specific characteristics in the digital environment. A cluster analysis of 590 German farm managers was used to identify five distinctive buyer segments based on five characteristics: dealer, brand and service orientation, price affinity and autonomous decision making. The results demonstrate that farmers place high value on personal contacts to stationary suppliers when purchasing crop protection products. Service orientation turned out to be a strong mediator of segment membership, while price and product brand are secondary to farmer segmentation. However, traditional typologies are only suitable for the digitization topic to a limited extent, as digital search and information behavior hardly differs. Even though digital information procurement is becoming increasingly interesting for all segments, an openness to e-commerce applies only to a small group of independent buyers. Concerning e-commerce attitudes, the perception of its advantages and the lack of personal contact differentiates the clusters the most. The results contribute to the scientific understanding of farmers’ information and purchasing behavior and provide initial approaches for the development of customer-centric corporate marketing strategies.

Consumers\u2019 adverse drug event reporting via community pharmacists: three stakeholder perception

BackgroundAdverse drug event (ADE) reporting is a significant process to increase consumer care and consumer safety associated with the use of medicines. An in-depth investigation into low ADE reporting by consumers and community pharmacists was undertaken to uncover interventions to improve reporting.MethodIn-depth interviewing of the three parties; consumers, pharmacists and employees of the Pharmacovigilance Center in Thailand, was used to collect the data. They were interviewed about ADE reporting experiences and contributing factors and problems of ADE reporting. Thematic analysis was used to interpret the results.ResultThe HPVC received few ADE reports from consumers. Most community pharmacists received ADE reports from consumers; however, the Pharmacovigilance Center received few ADE reports from community pharmacists. ADE reporting of community pharmacists and consumers were influenced by many factors which were categorized into four themes which were (1) “Cognition” (awareness, attitude and responsibility); (2) “Reporting process” (complication, competency, information deficiency, feedback, and resource); (3) “Inducer” (service orientation, acquaintanceship, motivation, severity level, regulatory and reward); and (4) “Obstacle” (doubt, belief and prosecution).ConclusionHealth professionals should motivate consumers to report ADEs. Building social responsibility and benefits and increasing knowledge of reporting process, channels, and system to both community pharmacists and consumers were recommended. Providing rewards and making community pharmacists feel comfortable to report ADEs by simplifying the ADE form and providing training, guidelines, and an ADR assessment tool can drive them to report ADEs. Feedback to consumers by confirming whether it was ADE and feedback to pharmacists that the Pharmacovigilance Center received their reports and their reports were utilized were also important.

From care packages to Zoom cookery classes: youth work during the COVID-19 “lockdown”

PurposeThis paper aims to explore the experience of one large Irish youth work organisation, Foróige, to measures introduced during the initial phase of COVID-19 in 2020. In the face of the unprecedented crisis including the closure of schools and curtailment of many youth services, this paper examines how the organisation responded and adapted its service offering.Design/methodology/approachQualitative semi-structured interviews were conducted with 12 senior managers and youth officers in Foróige to explore their perspectives on the organisation’s response. Participants were purposively sampled from across the operational management functions and also from regional levels and youth workers engaging in work “on the ground”.FindingsShifting from a face-to -face, relationship-based to a distanced mode of engagement with young people, colleagues and volunteers required significant adaptation of Foróige’s service model. Innovation took place both in the delivery platform and fundamentally, in its service orientation. The accelerated move to online youth work brought about by the pandemic enabled the organisation to embrace and learn from the challenges and opportunities posed by digital technology. Responding to the immediate and tangible needs of young people in receipt of services, staff found themselves working with families at the more basic levels of intervention.Originality/valueThis paper provides new insights into the nature of non-profit service innovation during a time of unprecedented crisis management. It highlights characteristics of organisational agility that can assist organisations in managing crises, while also pointing the way towards a more flexible operating model for youth work service delivery.

Penggunaan Metode Analytic Hierarchy Process Untuk Pembobotan Perilaku Kerja Dalam Penilaian Prestasi Kerja Dosen

Assessment of work performance consists of two elements, they are the employee's work goals and work behavior. The assessment of work behavior which consists of service orientation, integrity, commitment, discipline, cooperation and leadership that has been running so far is not considered objective between lecturers who have structural positions and ordinary lecturers. The purpose of this research is to produce a database information system that uses the AHP method to assist leaders in assessing work behavior. Work behavior between lecturers and structural officials will have different weights for some of the behavioral points assessed. AHP method is used to determine the weight of work behavior whose value is generated from the value of the interest ratio that has been entered. Result of this research is the value of work behavior according to the weight of each position and with predetermined criteria.. The system also generates the value of the Tri Dharma Tinggi activities for lecturers which include teaching and education, research, community service and supporting elements. System is made using visual basic programming and has been automated for AHP calculations and the value of lecturer activities. The weights generated by the AHP method are values that are consistent and feasible to use because they have been tested for consistency.

Kepemimpinan dan Inovasi Sektor Publik: Kunci Sukses Otonomi Daerah

Some successes stories of local government in the autonomy era, has proven urged by the courage of leader to make and apply innovations strategies. Keep in mind here is that not all changes are innovations, when the changes made an impact even less favorable for society and government. The role of leader is to determine the existence of innovation and organiza-tional change processes. But innovations and changes will not be run effectively when not supported by the parties affected by these changes both internal and external. In facts, there are many local governments that are still managed under the old pattern, that more advanced the power orientation and less put forward the spirit of public services orientation. Public managers who are committed and really want to realize these commitments are the souls that entrepreneurs seize opportunities as well as weaknesses smartly and follow them with prob-lem solving actions-oriented and increasing outputs. These leaders seem to become really agent of change and transformative leader.

A data management infrastructure for the integration of imaging and omics data in life sciences

BackgroundAs technical developments in omics and biomedical imaging increase the throughput of data generation in life sciences, the need for information systems capable of managing heterogeneous digital assets is increasing. In particular, systems supporting the findability, accessibility, interoperability, and reusability (FAIR) principles of scientific data management.ResultsWe propose a Service Oriented Architecture approach for integrated management and analysis of multi-omics and biomedical imaging data. Our architecture introduces an image management system into a FAIR-supporting, web-based platform for omics data management. Interoperable metadata models and middleware components implement the required data management operations. The resulting architecture allows for FAIR management of omics and imaging data, facilitating metadata queries from software applications. The applicability of the proposed architecture is demonstrated using two technical proofs of concept and a use case, aimed at molecular plant biology and clinical liver cancer research, which integrate various imaging and omics modalities.ConclusionsWe describe a data management architecture for integrated, FAIR-supporting management of omics and biomedical imaging data, and exemplify its applicability for basic biology research and clinical studies. We anticipate that FAIR data management systems for multi-modal data repositories will play a pivotal role in data-driven research, including studies which leverage advanced machine learning methods, as the joint analysis of omics and imaging data, in conjunction with phenotypic metadata, becomes not only desirable but necessary to derive novel insights into biological processes.

The Relationship between Service Climate, Employee Experience and Organizational Loyalty

The study aimed to explore the relationship between service climate, employee experience (EX) and employee organizational loyalty. Three questionnaires were used as research tools: Service Orientation Scale - Serv * or (Lytle, Hom, &amp; Mokwa, 1988), Employee Experience Index (Morgan, 2017) and Employee Loyalty Index -eNPS (Reichheld, 2011). 370 subjects participated in research, who evaluated the organization in which they were currently working. The Georgian version of Service Climate scale was developed in the research. The results of the research confirmed the research hypotheses: employee perceived service climate is positively related to employee experience and loyalty, the management service vision is the strongest predictor of employee experience and loyalty; In turn, the employee's loyalty to the organization will be influenced positively by employee's experience.

Employee Performance Evaluation at IPDN North Sulawesi Campus

Human Resources are the main principle in an organization to achieve the expected goals. The performance of employees, especially at the Institute of Domestic Administration (IPDN) North Sulawesi Campus, requires evaluation, especially for civil service educators, namely caregivers. This study aimed to determine the performance and factors that affect the performance of employees (caregivers) at IPDN North Sulawesi Campus. The research used a qualitative approach, while the data collection techniques in this study are observation, interviews, and documentation. The informants in this study were the Head of the Civil Service Administration, the Head of the Parenting Subdivision, the employees (caregivers), and the IPDN Praja North Sulawesi Campus. In general, the results of this research are; 1) The performance of employees (caregivers) of IPDN North Sulawesi Campus is in a reasonably good category, this is based on the results of research where from five employee performance indicators, there are still two indicators included in the good enough category, namely “service orientation and work discipline, 2) Factors that affect the performance of employees (caregivers) of IPDN North Sulawesi Campus, there are four namely a) HR development, b) work motivation, c) supervision and d) work environment. It can also be seen that of the four factors that affect employee performance, only one factor supports the performance of IPDN North Sulawesi Campus employees, namely the work environment. In comparison, the other factors are HR development and work motivation. Furthermore, supervision does not support IPDN North Sulawesi Campus employees (caregivers) taking out the job.

Генезис суворовского образования или где сегодня готовят государственного человека?

the review article presents a historical and pedagogical retrospective of Suvorov military education in educational organizations of the Ministry of Internal Affairs of Russia from the 40s of the XX century to the present, identifies problems and trends in the training of pupils of the Suvorov military schools of the Ministry of Internal Affairs of Russia, defines the essence of professional orientation of graduates-Suvorov service in the internal affairs bodies of the Russian Federation. The genesis of Suvorov education from the depths of cadet training and upbringing, the state and social nature of Suvorov education: the preparation of a statesman and the care of orphans of the dead servicemen and employees of internal affairs bodies. It has been determined that the Suvv military schools exercise the individual's right to choose an individual educational trajectory, on the one hand, and are obliged to fulfill the state order for training personnel for the activities of the internal affairs bodies of the Russian Federation, on the other.&#x0D; Such dualism gives rise to the contradictory interpretation of constitutional norms associated with the right of a citizen to choose not only the direction of education, but also the direction of professional activity.

A call for the library community to deploy best practices toward a database for biocultural knowledge relating to climate change

PurposeIn this paper, a call to the library and information science community to support documentation and conservation of cultural and biocultural heritage has been presentedDesign/methodology/approachBased in existing Literature, this proposal is generative and descriptive—rather than prescriptive—regarding precisely how libraries should collaborate to employ technical and ethical best practices to provide access to vital data, research and cultural narratives relating to climate.FindingsCOVID-19 and climate destruction signal urgent global challenges. Library best practices are positioned to respond to climate change. Literature indicates how libraries preserve, share and cross-link cultural and scientific knowledge. With wildfires, drought, flooding and other extreme or slow-onset weather events presenting dangers, it is imperative that libraries take joint action toward facilitating sustainable and open access to relevant information.Practical implicationsAn initiative could create an easily-accessible, open, linked, curated, secure and stakeholder-respectful database for global biocultural heritage—documenting traditional knowledge, local knowledge and climate adaptation traditions.Social implicationsOngoing stakeholder involvement from the outset should acknowledge preferences regarding whether or how much to share information. Ethical elements must be embedded from concept to granular access and metadata elements.Originality/valueRooted in the best practices and service orientation of library science, the proposal envisions a sustained response to a common global challenge. Stewardship would also broadly assist the global community by preserving and providing streamlined access to information of instrumental value to addressing climate change.

Explaining High Performance Among Indian Administrative Service (IAS) Officers: A Job Demands-Resources Perspective

Indian Administrative Service (IAS) officers are careerist senior civil servants (SCS) in the world’s largest democracy, holding senior roles of policymaking and implementation. Therefore, identifying exceptionally performing SCS to unravel their “job demands” along with “personal resources” should help with understanding how best to manage these critical human resources. Employing a qualitative approach, we interviewed 11 high performing IAS officers identified through a unique career progression index. Our data analysis revealed that the IAS suffers from the following job demands: difficulty in coordination with other departments and stakeholders, financial inadequacy, and dishonest subordinates or coworkers. This study also found that self-directed learning, personal reputation, empathy, and service orientation are essential personal resources for high-performing SCS. While expanding the list of job demands and personal resources in the public administration context, our research provides a deeper insight into the challenges confronting careerist SCS in lower-middle income developing countries.
