cloud computing

Microservices is an architectural style in software development that involves constructing a big solution using small, self-contained services. A set of services are connected via well-defined APIs and work together like a coherent system. The application of microservices architecture spans a wide range of domains, e.g., healthcare, finance, government, military, gaming, and entertainment. This article analyzes existing project architecture approaches for Node.js, and improves scalable project architecture for Node.js using shared dependencies.

Workflow is a sequence of repeated and controlled steps aimed at completing a specific task or work. The urgency of the task of optimizing such works contributed to the development of methods and means  of  operations  research  to  optimize  such  processes  for  the  needs  of  various  subject  areas. Information technologies to support such workflow are workflow engines that enable faster automation, ensure compliance with norms and standards, formalize business processes, improve communication, etc.

Cloud computing is emerging as a powerful computing paradigm for the efficient use of resources. However, decisions to move to cloud computing always remain risky from the customer's point of view, considering the benefits they get from it.

Serverless computing is a new and still evolving type of cloud computing, which brings a new approach to the development of information systems. The main idea of serverless is to give an approach of doing computing without dealing with a server to a user. Such approach allows to reduce the cost of the system building and system support. It allows small companies to concentrate on their own system designing instead of thinking about infrastructure building and supporting. Also, a big problem of providing the system security on high level is on cloud’s provider engineering support service.

An intellectual system of data deduplication and distribution in cloud storage facilities was developed. The resulting software has a user-friendly interface that allows you to backup and restore data. An analytical review of the methodological principles of the research is carried out, existing approaches to data backup with the use of data deduplication and distribution in cloud storage were analyzed, their advantages and disadvantages are highlighted. The advantages and disadvantages of modern data deduplication technologies are considered in detail.

The paper proposes a structure for implementing of the system for calculating the parameters of microelectromechanical systems using cloud technologies. Considered the advantages of this system over existing models.

The article reviews the architectural transformation of modern networks and their (mobile) services and applications. Periods of network services, Internet and cloud computing are posted. We describe the requirements for telecommunication networks in each of the individual stages of development and performance criteria specified network technologies.
The paper presents the measures that should be taken to improve the energy efficiency of modern technology making in the development of telecommunications networks of the future.

The problem of growth of the mobile data traffic and the number of services becomes global, moreover, volume and frequency of control traffic transmitted through the network are increasing, and therefore there is a need for its effective management to ensure the quality of service required by users and optimal use of mobile network resources. In such circumstances, the load on the server that is created in the process of establishing the connection and its serving has its considerations.

This paper is devoted to the numerical investigation of the availability at cloud service systems. In this paper criteria and constraints calculations were performed and obtained results were analyzed for synthesis purposes of distributed service platforms based on the cloud service-oriented architecture such as availability and system performance index variations by defined set of the main parameters.

The paper presents the main approaches to distributed organization of data in computer networks processing and organization of distributed applications. The main approaches to organization of distributed computing systems are described. The conception of GRID computing and comparative analysis of technologies and architectures of "cloud computing" and GRID systems creation are outlined. The estimations of the advantages and disadvantages of computing processes in web-systems are presented. The analysis of analytical models of cloud computing nodes is made.
