Microservice Architecture

The approach to organizing the automated calculations’ execution process using the web services (in particular, REST-services) is reviewed. The given solution will simplify the procedure of introduction of the new functionality in applied systems built according to the service-oriented architecture and microservice architecture principles. The main idea of the proposed solution is in maximum division of the server-side logic development and the client-side logic, when clients are used to set the abstract computation goals without any dependencies to existing applied services. It is proposed to rely on the centralized scheme to organize the computations (named as orchestration) and to put to the knowledge base the set of rules used to build (in multiple steps) the concrete computational scenario from the abstract goal. It is proposed to include the computing task’s execution subsystem to the software architecture of the applied system. This subsystem is composed of the service which is processing the incoming requests for execution, the service registry and the orchestration service. The clients send requests to the execution subsystem without any references to the real-world services to be called. The service registry searches the knowledge base for the corresponding input request template, then the abstract operation description search for the request template is performed. Each abstract operation may already have its implementation in the form of workflow composed of invocations of the real applied services’ operations. In case of absence of the corresponding workflow in the database, this workflow implementation could be synthesized dynamically according to the input and output data and the functionality description of the abstract operation and registered applied services. The workflows are executed by the orchestrator service. Thus, adding some new functions to the client side can be possible without any changes at the server side. And vice versa, adding new services can impact the execution of the calculations without updating the clients.

В настоящее время большинство сервисов переходят в онлайн, что позволяет пользователям получать услугу в любое время. Высокая доступность услуги приводит к росту количества пользователей, что влечет за собой повышение нагрузки на систему, поэтому необходимо уделить особое внимание отказоустойчивости системы перед началом ее разработки. Рассматриваются основные проблемы высоконагруженных систем, способ оптимизации приложения путем распараллеливания задач по ядрам процессора. В данной статье описывается необходимость перехода на микросервисную архитектуру, ее недостатки и способы их устранения. В процессе решения проблем масштабирования, затрагиваются проблемы распределенных транзакций и долгого ответа от сервера. Nowadays, most of the services are moving online, which allows users to receive the service at any time. The high availability of the service leads to an increase in the number of users, which entails an increase in the load on the system, therefore, it is necessary to pay special attention to the fault tolerance of the system before starting its development. The main problems of high-load systems, a way to optimize an application by parallelizing tasks across processor cores are considered. This article describes the need to migrate to a microservice architecture, its weaknesses, and how to fix them. In the process of solving scaling problems, the problems of distributed transactions and long response from the server are addressed.

UNSTRUCTURED The Internet of Medical Things (IoMT) combines medical devices and applications connected to healthcare information technology systems using network technologies. With the flourishing adaptation rate of Internet-enabled medical devices in healthcare applications, we need to guarantee the security and privacy of electronic health records (EHRs) and communications among these IoMT devices, exposed web services, and the underlying infrastructure. This research is a proof-of-concept (PoC) study for implementing an integrated security solution with Spring Security and KeyCloak open-access platform (SSK) to safeguard microservice architecture application programming interfaces (APIs). Subsequently, we extended the security solution with a virtual private network (VPN), Bcrypt hash, API key, network firewall, and secure socket layer (SSL) to build up a digital infrastructure following the Norwegian data protection policies and General Data Protection Regulation (GDPR). In this study, we have not proposed any new security solution; however, we have focused on accomplishing a hybrid security solution based on the established frameworks (e.g., Spring Security) and open-access software product (e.g., Keycloak) to protect microservice APIs for a health eCoach system as a PoC study. This study describes the methodological, technical, and practical considerations to protect REST interfaces only and ensuring the privacy of data in the system. We validate our SSK security implementation by theoretical evaluation and experimental testing. In addition, we compare the test results with related studies qualitatively to determine the effectiveness of the hybrid security solution (SSK).
