Item Cloud Key-Value Storage(Видавництво Львівської політехніки, 2023-02-28) Pykulytsky, Oleh; Havano, Bohdan; Lviv Polytechnic National UniversityThe paper represents all the stages of designing, architecting, and developing cloud-based key-value storage. This work aims to bring new approaches to distributed data systems. The authors focus on the security and productivity of the project as well as security and maintainability. The authors have studied the use of hash tables in a multithreaded environment. Architectural approaches and tools have been described. The general structure of the keyvalue storage server has been presented. The server algorithm has been presented. Our research delves into the intricate nuances of utilizing hash tables in a multithreaded environment, shedding light on the intricacies and challenges of managing concurrent access to keyvalue data structures. The authors have explored the tradeoffs between lock-free designs and traditional locking approaches.Item Cloud managers – an innovative approach to the management of the library information resources(Commission of Motorization and Energetics in Agriculture, 2017) Rzheuskiy, A.; Kunanets, N.; Kut, V.; Lviv Polytechnic National University; Augustine Voloshin Carpathian UniversityThe innovation of application of cloud managers is described in the article. The authors emphasize that the innovative direction of development of information activities is the integration of Web platforms (social networks and cloud storages) for creating a unified communication space and storage for large amount of information. Tool that provides this development are cloud managers. For library institutions using such technologies will create the favorable and flexible serviceoriented system for providing users with information resources. For determination of free cloud managers and selected among them a benchmark, the methods of benchmarking and expert evaluation were used in the research. The algorithm for operation with every service is given. The following technological capabilities: “integration with cloud storage”, “cloud disk space manager”, “multimedia playback,” “presence of workspace” for collaboration were taken into account. The result of the study is to determine the cloud manager that can serve as a benchmark for providing free cloud services with a wide range of technological capabilities.Item Use of a cloud storage for implementation informational processes(Commission of Motorization and Energetics in Agriculture, 2017) Boyko, N.; Lviv Polytechnic National UniversityIn this paper, description of a concept of cloud storage is offered. One of the most practical methods of storing required information to cloud storage is also considered. Method of creating screenshots is proposed. Theoretical research is carried out and there are justified advantages and disadvantages of different methods of storing information in social networks. The best technique of creating screenshots has been practically implemented. Problems that might come up while working with approach given in this article and its solutions are stipulated. There is analyzed a necessity of setting a zoom parameter which is to transfer after transmitting size value of the picture in social networks. In the article the parameter that specifies the width of the final image and clearly affects the quality of the image is also considered. There is analyzed the effectiveness of creating an information system that saves time for such information processes as tracking the photo and its comments. In the paper the task of changing bets, which are not immediately fixed in social networks is optimized. Also there is implemented in practice a scalability problem of information processes in social networks. In the article a separation of the script is also put into practice. One part of which directly performs the request of image and downloads it to cloud storage. With help of another part the information process is transmitted on the photo where the user identifies.Item Ключові компоненти інформаційно-навчального середовища сучасного ВНЗ(Видавництво Львівської політехніки, 2015) Шелестова, АннаРозглянуто значення та вплив інформаційно-комунікаційних технологій на розвиток та вдосконалення інформаційно-навчального середовища сучасного ВНЗ. Окреслено тенденції подальшого розвитку та вдосконалення процесів інформатизації ВНЗ. Importance and influence of information and communication technologies on the development and improvement of the information and education environment of the modern university are considered. Trends of the further development and improvement of informatization processes of the university are outlined.
