Method of data dedublication and distribution in cloud warehouses during data backup

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.

Stages of the modern it services development and energy effectiveness of network technologies

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.

Management of Multiple Stage Queuing Systems

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.

The Investigation of the Availability at Cloud Service Systems

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.
