Based on the diversified technology and the cross-validation mechanism, the N-variant system provides a secure service architecture for cloud providers to protect the cloud applications from attacks by executing multiple variants of a single software in parallel and then checking their behaviors' consistency. However, it is complex to upgrade current Software as a Service (SaaS) applications to adapt N-variant system architecture. Challenges arise from the inability of tenants to adjust the application architecture in the cloud environment, and the difficulty for cloud service providers to implement N-variant systems using existing API gateways. This paper proposes SecIngress, an API gateway framework, to overcome the challenge that it is hard in the cloud environment to upgrade the applications based on N-variants system. We design a two-stage timeout processing method to lessen the service latency and an Analytic Hierarchy Process Voting under the Metadata mechanism (AHPVM) to enhance voting accuracy. We implement a prototype in a testbed environment and analyze the security and performance metrics before and after deploying the prototype to show the effectiveness of SecIngress. The results reveal that SecIngress enhances the reliability of cloud applications with acceptable performance degradation.

Digital twin (DT) is a hot topic in information engineering, which has been introduced into the intelligent solution of the power grid system to deal with the reliability assurance issues of complex systems. Due to the lack of an operational application architecture model, it is impossible to map the complex system comprehensively. Based on the review of the concept model of DT and the current research situation in the smart grid (SG), an OKDD [i.e., ontology-body (OB), knowledge-body (KB), data-body (DB), and digital-portal (DP)] model of digital twin body (DTB) is proposed and specified in detail. Taking a vacuum circuit breaker and a 35 kV substation of the power grid as examples, the OKDD is applied in the DTB construction, and the developed prognostic and health management (PHM) system demo is practiced in a 110 kV substation simply. The approach is proved to be feasible preliminarily. This model provides a novel method for the unified description and standardization of DTB, which is conducive to the hierarchical creation (unit-system-system of systems) for complex systems. Meanwhile, it can represent complex physical entities more comprehensively, and enable the reuse of knowledge and the duplication of similar unit-level DTB rapidly. Thus, this research provides a new reference for the practical application of DT.

One of the key elements of precision agriculture is the farm management information system (FMIS) that is responsible for data management, analytics and subsequent decision support. Various FMISs have been developed to support the management of farm businesses. A key artefact in the development of FMISs is the software architecture that defines the gross level structure of the system. The software architecture is important for understanding the system, analysing the design decisions and guiding the further development of the system based on the architecture. To assist in the design of the FMIS architecture, several reference architectures have been provided in the literature. Unfortunately, in practice, it is less trivial to derive the application architecture from these reference architectures. Two underlying reasons for this were identified. First of all, it appears that the proposed reference architectures do not specifically focus on FMIS but have a rather broad scope of the agricultural domain in general. Secondly, the proposed reference architectures do not seem to have followed the proper architecture documentation guidelines as defined in the software architecture community, lack precision, and thus impeding the design of the required application architectures. Presented in this article is a novel reference architecture that is dedicated to the specific FMIS domain, and which is documented using the software architecture documentation guidelines. In addition, the systematic approach for deriving application architectures from the proposed reference architecture is provided. To illustrate the approach, the results of multi-case study research are shown in which the presented reference architecture is used for deriving different FMIS application architectures.

Data is stored in the cloud, and applications remain on traditional servers. This is also a common architecture that appears in the current process of migration from traditional application architecture to cloud computing architecture. This makes the efficiency and speed between traditional application servers and cloud storage a performance bottleneck for the entire system architecture. At present, the design of almost all cache systems in cloud storage addresses the performance bottlenecks of the system architecture based on the local characteristics of access, that is, the use of the temporal and spatial local characteristics of cloud storage to design the cache system. This article summarizes the prefetching technology and caching technology in cloud storage cache from the perspective of memory hierarchy, and verifies the temporal and spatial locality characteristics of cloud data access through the access of NASA-HTTP log data set.

Microservice-based edge computing is a key technology to support power system to adapt to the high concurrency and diversification of application in power Internet of Things. Workload modeling is not only the basis for analyzing the logical design and computing resource requirements of application, but also the premise of optimizing the computing resource configuration and scheduling of edge computing. In this paper, a workload modeling method for microservice-based edge computing is proposed. The composition of an application and the logical relationship among the microservices are elaborated. Then, the topological structure graph and model are proposed to describe the logical relationship of the microservices. Based on the established model, the workload model is formulated to calculate the computing resource demand and latency of the application. Besides, a microservice-based workload evaluation algorithm is proposed to obtain the configuration results and the latency performance. The influence of the application architecture, topological structure of microservices and virtualization technology of edge computing terminal are analyzed. Simulation results verify the validity of the proposed model and method.

Dynamic line rating is a technology that can be used to improve the transmission efficiency and capacity of the existing power system without changing the system structure or breaking the current technical specification. It is an economical and feasible method to meet the increasing power demands and the needs for new energy integration. In order to ensure the safe and stable operation of power system, the specific technologies and application methods affecting the reliability of DLR are discussed. The main limitations of data acquisition technology of transmission lines are analyzed, the advantages and disadvantages of different perception analysis methods are classified, several application architectures of the DLR system are compared, and some applications of current DLR technologies in actual engineering are discussed. The problems existed in the technologies of DLR are pointed out from four aspects: data acquisition, perception analysis, application architecture, and engineering practice, such as the quality of data acquisition is low, the dependence of perceptual analysis on parameters and the data collected is high, the application architecture is open-loop, the analysis on the overall security of the power grid is deficient. Finally, the future research direction is pointed out.

Fog computing promises to extend cloud computing to match emerging demands for low latency, location-awareness and dynamic computation. It thus brings data processing close to the edge of the network by leveraging on devices with different computational characteristics. However, the heterogeneity, the geographical distribution, and the data-intensive profiles of IoT deployments render the placement of fog applications a fundamental problem to guarantee target performance figures. This is a core challenge for fog computing providers to offer fog infrastructure as a service, while satisfying the requirements of this new class of microservices-based applications. In this article we root our analysis on the throughput requirements of the applications while exploiting offloading towards different regions. The resulting resource allocation problem is developed for a fog-native application architecture based on containerised microservice modules. An algorithmic solution is designed to optimise the placement of applications modules either in cloud or in fog. Finally, the overall solution consists of two cascaded algorithms. The first one performs a throughput-oriented partitioning of fog application modules. The second one rules the orchestration of applications over a region-based infrastructure. Extensive numerical experiments validate the performance of the overall scheme and confirm that it outperforms state-of-the-art solutions adapted to our context.

As the role of blockchain technology in various industries becomes more and more important, the technical limitations of its consensus mechanism, private key management and smart contracts are gradually emerging. However, security events such as blockchain platform applications are emerging one after another. As a new round of transformative power in the network era, it combines the blockchain with existing technologies to generate new formats and new models. Technology applications and existing cybersecurity regulatory policies have brought new challenges. This paper analyzes the typical application architecture of blockchain technology, and analyzes the security risks of blockchain application architecture from key layers such as storage layer, protocol layer, extension layer, and application layer. This article combines the DOC mechanism with IOT application scenarios to propose a blockchain-based confidential IOT service model (Beekeeper 1.0) that supports first-order homomorphic multiplication, and a blockchain-based confidential IOT service model that supports high-order homomorphic multiplication (Beekeeper 2.0), Beekeeper 2.0 significantly improves Beekeeper 1.0 in server capabilities, verification efficiency, verification key length, and device work diversity. This article finds that the chain code call delay basically increases with the increase in the transaction sending rate. When the transaction sending rate reaches 300TPS, the chain code calling delay only increases a little, and when the transaction sending rate reaches 300TPS, the success rate of the transaction on the chain increases. Finally, the average blockchain access delay increases with the increase in the transaction sending rate. The blockchain access delay is affected by less throughput, and the transaction success rate is stable at 98%.

Current trends in the housing and utilities sector are associated with a value-oriented approach, which implies that the key aspect in designing a product or service is the value received by the consumer.Aim.

The authors form the value proposition of a utility company (through the example of a water supply and disposal company), determine the role of data collection, transmission, processing, and analysis technologies in the implementation of this value proposition, and develop a model for an architectural solution for a value-oriented utility company.Methods. This study uses an architectural approach to the design of enterprise management systems.Results. The study proposes a model of an architectural solution for a value-oriented utility company that describes the interaction between the user and corporate architecture of value proposition implementation. This model serves as a basis for creating detailed requirements for the services of application architecture, data architecture, and technological architecture of the utility system.Conclusions. The architectural model of a utility company should make allowance for the requirements of compliance with the principles of value-oriented activity - from business services to IT systems and technological architecture. Personalized data collection is one of the most important conditions for the implementation of a value-oriented approach. A model for integrating data processing technologies in the architectural solution of a utility company will allow it to develop and implement the services necessary for value proposition implementation.

Resource sharing and mass storage in server farms provided by cloud platforms save huge amounts of energy. However, optimizing energy consumption at the server room is not enough, being desirable to perform energy optimization of cloud services at the application level. In cloud computing a tailored configuration of services is deployed for each client (tenant), requiring different energy consumption optimizations. Indeed, energy consumption of cloud services depends on several factors determined by the context and usage of the applications. So, to evolve a cloud application to new requirements of energy efficiency implies to perform custom-made adaptations for each tenant. Thus, managing the evolution of a multi-tenant application with hundreds of tenants and thousands of different valid architectural configurations can become intractable if performed manually. This paper proposes a product line architecture approach that: (1) uses cardinality-based variability models to model each tenant as a clonable feature, and (2) automatizes the process of evolving the multi-tenant application architecture when the energy requirements change. The implemented process is efficient for a high number of tenants in a reasonable time.

Blockchain-based cloud application (BCP) is an emerging cloud application architecture. By moving trust-critical functions onto blockchain, BCP offers unprecedented function transparency and data integrity. Ethereum is by far the most popular blockchain platform chosen for BCP. In Ethereum, special programs named smart contracts are often used to implement key components for BCP. By design, users can send transactions to smart contracts, which will automatically lead to code execution and state modification. However, unlike regular programs, smart contracts are restricted in execution by gas limit, i.e., a form of runtime resource. If a transaction uses up all available gas, an out of gas exception () will trigger, reverting state until right before that transaction.In this work, we study the out of gas exceptions (or gas exceptions in short) on Ethereum empirically for the very first time. In particular, we collect exception transactions using an instrumented Ethereum client. By investigation, we found gas exceptions stand out in terms of both occurrences and losses. Moreover, we focused on individual contracts and transactions, aiming at discovering and identifying common causing factors triggering these exceptions. At last, we also investigate existing tools in preventing gas exceptions. Our results suggest further research and study in this direction.

Sonny Medika Bidan Enen Clinic is a health service provider that has skilled medical personnel, but data management at the clinic is still done manually. The risk of errors in storing and managing medical record data caused by human error is still quite high, so that it can reduce the quality of service. With the design of the EMR (Electronic Medical Record) system it can help the process of managing medical record data, so that service and archive storage is better and can reduce errors that occur. The design of the EMR is done by the EAP (Enterprise Architecture Planning) method using the Zachman Framework. There are four stages carried out which include the seven main components of EAP, namely Design Initiation, Business Modeling, Current Technology Systems, Data Architecture Design, Application Architecture design, Technology Architecture Design, and Implementation Plan. The results of the EMR design by the EAP method successfully defined 3 business processes. In the data architecture produces 7 data entities, in the application architecture 4 application proposals are generated, and in the technology architecture the proposed architectural technology design is generated .

Human language is a versatile tool for communicating mental models between speakers of a language. This paper presents the TextMap system, a logic-based system for generating visuospatial representations from textual input. TextMap combines a minimalistic parser with a simple model counting mechanism to automatically extract coordinate information from propositional Horn-logic knowledge bases encoding spatial predications. The system is based on a biologically inspired low-level bit vector mechanism, the activation bit vector machine (ABVM). It does not require an ontology apart from a list of which tokens indicate relations. Its minimalism and simplicity make it a general purpose visualization or imagery tool. The paper describes the TextMap application architecture as well as the key algorithms forming the ABVM core. The system is evaluated with respect to a larger case study of a geographic layout of 13 cities demonstrating capabilities as well as current shortcomings for a complex scenario of a human mental map description.

Applications architecture is the baseline of any organizational activity, which main goal is to provide the executional environment for businessprocesses in order to deliver products or services to satisfy customer needs and generate revenue. Nowadays, large software engineering projectsalways begin with the architecture design phase, despite the waterfall or agile methodology is used by a software development team. Applicationsarchitecture design is the most important and, at the same time, error-prone stage of the whole software engineering project. It is well-known thatdesign shortcomings made on the design phase may increase drastically to testing and maintenance phases. Further costs to defects fixing may behundred times higher in the later project stages in compare to the design stage on which applications architecture is defined. Common system designsolutions, which were proven on practice and used in many projects, are known as architectural patterns. Software architecture patterns are consideredas building block for system implementation. The most popular and efficient way to share architectural patterns are graphical models that used as anyother blueprints of engineering solutions. Applications architecture models are built to represent system design, whereas, such models are alreadybased on certain patterns as the industry best practices. Hence, in this paper we consider a relevant problem of applications architecture modelsanalysis, which relevance is defined by those fact that designed blueprints of information systems and other software solutions should be carefullychecked for all presumable inefficiencies in order to avoid extra efforts and related costs for defects fixing in the later project stages. It is proposed touse ArchiMate enterprise architecture modeling language, since it can be used not only to represent applications architecture, but is connection tobusiness and technology layers. In order to evaluate applications architecture models, respective ArchiMate metamodel is considered and representedas labeled directed graph, and coupling software metric is selected for analysis.

На сегодняшний день крупные проекты программной инженерии всегда начинаются с фазы проектирования архитектуры, несмотряна то, что команда разработчиков программного обеспечения использует водопад или же гибкую методологию. Проектирование архитектуры приложений является важнейшим и одновременно наиболее уязвимым к ошибкам этапом всего проекта по разработке программногообеспечения. Хорошо известно, что значимость недостатков, предполагаемых на этапе проектирования, может резко увеличиться припереходе к этапам тестирования и сопровождения. Дальнейшие затраты на устранение дефектов могут быть в сто раз выше на более позднихстадиях проекта, чем на этапе проектирования, на котором определяется архитектура приложений. Распространенные решения попроектированию систем, проверенных на практике и используемых во многих проектах, известны как архитектурные шаблоны. Шаблоныархитектуры программного обеспечения рассматриваются как строительные блоки для реализации всей системы. Самым популярным иэффективным способом обмена архитектурными шаблонами являются графические модели, которые используются как и любые другиечертежи инженерных решений. Модели архитектуры приложений предназначены для представления проектов системы, причем такиемодели уже базируются на определенных шаблонах как лучших отраслевых практиках. Следовательно, в данной работе рассматриваетсяактуальная проблема анализа моделей архитектуры приложений, важность которой определяется тем, что разработанные проектыинформационных систем и других программных решений должны быть тщательно проверены на наличие всех вероятных неэффективных решений для того, чтобы избежать дополнительных усилий и связанных с этим расходов, направленных на устранение дефектов на позднихстадиях проекта.

На сьогоднішній день великіпроекти програмної інженерії завжди починаються з фази проектування архітектури, незважаючи на те, що команда розробниківпрограмного забезпечення використовує водоспад або ж гнучку методологію. Проектування архітектури застосунків є найважливішим і,водночас, найбільш вразливим до помилок етапом усього проекту з розробки програмного забезпечення. Добре відомо, що значущістьнедоліків, припущених на етапі проектування, може різко збільшитися при переході до етапів тестування та супроводу. Подальші витрати навиправлення дефектів можуть бути у сто разів вищими на більш пізніх стадіях проекту, ніж на етапі проектування, на якому визначаєтьсяархітектура застосунків.

In recent years, Solar power plants are currently developed rapidly, where solar power plants don't cause environmental damage. This generator utilizes sunlight as its input source which environmentally friendly, when sunlight is converted into direct current and voltage that can be stored in batteries. Therefore, the solar energy industry needs to have high efficiency, competitive pricing, and durability. With the right information technologies and developing application systems, it can help to optimize business processes and integrating information systems. But the fact there are many industries that do not apply information technology correctly into their business. In this research, provide to the best solution for applying the enterprise architecture framework correctly. The purpose of this paper is to design a manufacturing industry information system that is in accordance with the business model canvas and enterprise architecture. The design also discusses the development of a large and integrated information system with other systems. The study of Business Model Canvas is a business model that can explain and focus on nine business aspects with a solid strategy. Studies of the ArchiMate core Framework is the framework used to classify elements of the ArchiMate core language. These two methods are expected to be able to design an enterprise information system architecture consisting of business architecture, application architecture, information architecture and technology architecture as a result of the study. The result is a more complete system design to meet system requirements for users, integrated with existing system modules and no system duplication occurs.

Biodiversity data is obtained by a variety of methodological approaches—including observation surveys, environmental sampling and biological object collection—employing diverse sample processing protocols and data transformations. While complete and accurate accounts of these data-generating processes are important to enable integration and informed reuse of data, the structure and content of published biodiversity data currently are often shaped by specific application goals. For example, data publishers that export specimen-based data from collection management systems for inclusion in aggregations like those in the Global Biodiversity Information Facility (GBIF) must frequently relax their internal models and produce unnatural joins to fit GBIF’s occurrences-based data structure. Third-party assertions over these aggregated data therefore assume the risk of irreproducibility or concept drift. Here we introduce process- and state-based representation of object histories as the main organizing principle for data about specimens and samples in Digital Information System for Natural History Data (DINA, Glöckler et al. 2020)-compliant collection management software (Fig. 1). Specimens, samples and objects in general are subjected to a variety of processes, including planned actions involving the object, e.g., collecting, preparing, subsampling, loaning. Object states are any particular mode of being of an object at a certain point in time. For example, any one intermediate step in preparing a collected specimen for long-term conservation in a collection would constitute an individual object state. An object’s history is the entire chain of these interrelated processes and states. We argue that using object histories as main conceptual modeling paradigm in DINA offers the generality required to accommodate a diverse, open set of use cases in biodiversity data representation, yet also offers the versatility to serve as basis for use-case specific data aggregation and presentation. Specifically, a representation based on object histories provides a coherent structure for documenting individual processes and states for any given object and for linking this documentation (e.g., textual descriptions or images pertaining to a given process or state), a natural representational structure of the real-world sequence of processes an object participates in and for the data generated in these processes (e.g., a DNA-extraction procedure and sequence information generated on its basis), a straightforward structure to link data about related objects (e.g., tissue samples, the biological specimen a bone is derived from) in a network of connected object histories. a coherent structure for documenting individual processes and states for any given object and for linking this documentation (e.g., textual descriptions or images pertaining to a given process or state), a natural representational structure of the real-world sequence of processes an object participates in and for the data generated in these processes (e.g., a DNA-extraction procedure and sequence information generated on its basis), a straightforward structure to link data about related objects (e.g., tissue samples, the biological specimen a bone is derived from) in a network of connected object histories. The approach is designed to be embedded in DINA’s modular application architecture, so that information on object histories can be accessed via corresponding APIs either through its own interfaces (Fig. 2) or by integration with external web services (Fig. 3). Viewing collection management tasks as part of object histories also informs delineation of modules to support these tasks with specialized functions and interfaces. It also admits the use of persistent, dereferencable identifiers for individual processes and states in object histories and for linking their representations to elements in ontologies and controlled vocabularies. In this contribution to the symposium, DINA's object histories as a main organizing principle for collection object data will be discussed and the utility of using it in the context of modular application architecture, data federation, and data integration in projects like BiCIKL will be illustrated.

Cloud computing is a paradigm that has already evolved. Cloud computing moved widely to microservices from monoliths. The modular cloud application has gained attention for Microservices. Intensive network communication is required to call the interdependent microservices operating inside the cloud nodes. This research focuses on container-based microservices pre-distribution techniques and proposes two distribution strategies i.e. design pattern distribution and random distribution. The microservices are arbitrarily distributed to the available data centers in the random allocation method. While the microservices are clustered in the pattern distribution based on behavioral design patterns, which identify common contact patterns between entities. A custom-built modeling environment has been used to evaluate the proposed method. The findings revealed that the pre-distribution of microservices in accordance with the application architecture trend led to substantial less response time for the calls made to services hosted at geographically dispersed data centers.

This work proposes an application of the Internet of Multimedia Things (IoMT) for monitoring wildlife using edge computing. The application architecture was designed considering all stages from the collection of data in nature to delivery to the user. For this, the application architecture is organized into three services: edge, distribution and delivery. All application services were implemented without the use of commercial solutions, serving as a guide for developers who want to implement their own monitoring. As a study case, the application implemented in this work is that of monitoring birds calling, and was designed based on the Brazilian protocol for monitoring birds. Monitoring wildlife is a necessary task and often requires tasks in places that are difficult to access.

Knowledge graph technology has developed rapidly in recent years, and it is widely used in various scenarios, such as intelligent semantic search, intelligent in-depth question answering and mobile personal assistants.

The massive proliferation of sophisticated technologies into the heart of traditional Industrial Control Systems has given birth to “smart Industrial Cyber–Physical Systems” (ICPS). While this industrial revolution has brought upon a wide range of advantages, it also raised new design challenges and exposed ICPS to a new breed of cyber–physicalattacks. This paper aims to integrate security primitives (e.g., enforcing/verifying data authenticity) in control applications by formulating an innovative architectural paradigm shift. More specifically, our proposal is twofold. We elaborate a novel security-aware control application, which: (i) defines a new control application architecture embracing two security primitives that are called at the beginning and at the end of each program to verify and to enforce the required security properties; and (ii) runs the key management code as a separate program in order to isolate its implementation and to ensure its minimal interference with the rest of the programs. Then, we design a lightweight key distribution protocol exploiting the characteristics and computational advantages of symmetric key cryptography and hash functions. Extensive experimental results on a testbed replicating the precise hardware and software of a node from a Romanian gas transportation network, demonstrate the effectiveness of the proposed scheme and its applicability to resource-constrained ICPS.

The diversification of computing resources and the increasing complexity of resource demand from applications in terms of type, granularity, and quantity call for more efficiency in resource scheduling. To meet this challenge, this paper proposes a resource description model based on a quantized polygon. It explores the theoretical basis for the multilateral complementarity strategy (MCS), analyzes the basic mechanisms and application architecture of the MCS, and, finally, proposes the multi-dimensional quantized polygon (MQP) algorithm-a multi-dimensional resource scheduling algorithm based on multilateral complementarity (MC-MDRS algorithm). The experiments show that the multi-dimensional resource scheduling strategy based on the MQP, when implemented in an environment in which multi-dimensional (3 ≤ d ≤ 6) computing resources are provisioned, can effectively respond to the requests for various computing resources by granular services and facilitate the deployment of granular application services arriving in batches. The analysis of the experimental results indicates that the MQP algorithm outperforms other multi-dimensional resource scheduling algorithms by 2%-5% in node utilization.

The development of software applications has now shifted from desktop to mobile devices. Mobile application developers have been facing hardware configuration and network communication constraints in native, hybrid, and mobile web-based software architecture for a long time. Progressive Web Application is new research in this direction, created in order to overcome the limitations of native, hybrid, and mobile web-based application architecture for mobile devices. The Progressive Web Application architecture consists of a single software application which runs on multiple operating systems (android, iOS, and window phones) efficiently, uses device memory, and is even accessible in the event of no internet connection. Many IT companies have reported overall improvement in their mobile application user base after switching to Progressive Web Application. The recent discussions about Progressive Web Application on the google platform predict a demanding future. Hence, this article seeks to investigate the validity of claims that the Progressive Web Application has the edge over native, hybrid, and mobile web application architecture. The study uses the Analytical Hierarchy Process for deciding which of the architecture types suites the development of a mobile application based on three established constraints. The study outcome will aid software development communities in comprehending the Progressive Web Application and motivate them to use it in the development of an optimized mobile application.

The presented agent-based framework (Acromovi - an acronym in Spanish which stands for Cooperative Architecture for Intelligent Mobile Robots) was born from the idea that teamworking is an essential capability for a group of multiple mobile robots (Jung & Zelinsky, 1999; Mataric, 1998). In the last years, there is an increasing interest in the development of systems of multiple autonomous robots, so that they exhibit collective behaviour. This interest is due to the fact that having one single robot with multiple capabilities may waste resources. Different robots, each one with its own configuration, are more flexible, robust and cost-effective. Moreover, the tasks to achieve may be too complex for one single robot, whereas they can be effectively done by multiple robots (Arai et al., 2002). In this work is described the design and implementation of a distributed architecture for the programming and control of a team of coordinated heterogeneous mobile robots, which are able to collaborate among them and with people in the accomplishment of tasks of services in daily environments, the Acromovi architecture. Acromovi architecture is a framework for application development by means of embedding agents and interfacing agent code with native low-level code. It addresses the implementation of resource sharing among all the group of robots. Cooperation among the robots is also made easier in order to achieve complex tasks in a coordinated way. Moreover, in this work is emphasized the reusability of software, allowing the programmer to seamlessly integrate native software components (vision libraries, navigation and localization modules) , by means of agent wrappers, providing the programmer with a set of tools for mobile robots. Also, it allows sharing the robots’ resources among the team and an easy access to the robots’ elements by the applications. Other important characteristics of the Acromovi architecture are the scalability and ease-of-use. Though robot programming has been extensively done in C or C++ languages, a Java-based multiagent development system was chosen to develop the architecture of our team of robots (Nebot & Cervera, 2005a). Among Java strengths, those particularly pursued were the high-level communication capabilities, and the native interface to existing C/C++ code. On the other hand, Acromovi architecture is a distributed architecture that works as a middleware of another global architecture for programming robots. Though any common agent architecture can be used, it has been implemented by means of the JADE (Java Agent

Microservice is an architecture that can solve many problems in a monolithic architecture. One of the problems is the ability to handle many concurrent users. The existing monolithic application can be restructured into microservices to increase robustness in handling a lot of users, without exception native mobile application. This study aimed to restructure the existing native mobile application named TemanBisnis into microservices. The restructuring process can be done by splitting the application features according to its business domain into one service. Two microservice architecture designs were proposed in this study, named 3-1 architecture and 2-1-1 architecture. Both architectures can handle up to 100 concurrent users, although they start to produce errors. By performance, the 3-1 architecture is better than the 2-1-1 architecture. In the end, an existing native mobile application can be restructured into microservices. The 3-1 architecture should be adopted to achieve the best results between these two architectures.

Background Healthcare relies on health information systems (HISs) to support the care and receive reimbursement for the care provided. Healthcare providers experience many problems with their HISs due to improper architecture design. To support the design of a proper HIS architecture, a reference architecture (RA) can be used that meets the various stakeholder concerns of HISs. Therefore, the objective of this study is to develop and analyze an RA following well-established architecture design methods. Methods Domain analysis was performed to scope and model the domain of HISs. For the architecture design, we applied the views and beyond approach and designed the RA’s views based on the stakeholders and features from the domain analysis. We evaluated the RA with a case study. Results We derived the following four architecture views for HISs: The context diagram, decomposition view, layered view, and deployment view. Each view shows the architecture of the HIS from a different angle, suitable for various stakeholders. Based on a Japanese hospital information system study, we applied the RA and derived the application architecture. Conclusion We demonstrated that the methods of the software architecture design community could be used in the healthcare domain effectively and showed the applicability of the RA.
