cloud computing

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.

The article deals with virtualization technology, its development and methods development and communication of cloud computing, analysis of technical feasibility of implementing virtualisation and current problems, described the benefits of virtual infrastructure.

The paper analyzes the architectural approaches for building cloud data warehouses. The different approaches, including concentrated and distributed storages, were examined and effectiveness of their use was analyzed.

The paper describes the infrastructure of cloud technology platform for the development of tourism business planning and proposes its architecture, based on five performance levels of service tourist business. Also a library of software modules to address optimization tasks and planning data security platform tourism are described.
