   <abstract xml:lang="ru">
    <p>Экспоненциальный рост объемов данных в облачных средах делает критически важной задачу их эффективного сжатия для оптимизации использования ресурсов хранения, пропускной способности сети и вычислительных мощностей, что напрямую влияет на экономическую и операционную эффективность. Цель: провести сравнительный анализ современных алгоритмов сжатия без потерь для определения оптимальных сценариев их применения в облачных платформах. Результаты: систематизированы принципы работы и классификация современных алгоритмов сжатия без потерь. На основе сравнительного анализа по ключевым параметрам (коэффициент сжатия, скорость операций, ресурсоемкость) определены сценарии оптимального применения алгоритмов Gzip, LZ4, Zstandard и Brotli в облачных сервисах. Практическая значимость: полученные результаты можно использовать для оптимизации затрат на облачную инфраструктуру и повышения производительности распределенных систем обработки данных. Обсуждение: проведенный анализ демонстрирует, что выбор алгоритма зависит от специфики задачи. Использование аппаратного ускорения позволяет значительно повысить производительность компрессии.</p>

    <p>The exponential growth of data volumes in cloud environments makes it critically important to efficiently compress this data to optimize the use of storage resources, network bandwidth and computational power, which directly affects economic and operational efficiency. Purpose: to conduct a comparative analysis of modern lossless compression algorithms to identify optimal scenarios for their application in cloud platforms. Results: the principles of operation and classification of contemporary lossless compression algorithms have been systematized. Based on a comparative analysis of key parameters, such as compression ratio, operation speed, and resource intensity, optimal application scenarios for the Gzip, LZ4, Zstandard and Brotli algorithms in cloud services have been determined. Practical significance: the results obtained can be used for optimizing costs associated with cloud infrastructure and for improving the performance of distributed data processing systems. Discussion: the conducted analysis demonstrates that the choice of algorithm depends on the specific characteristics of the task. The use of hardware acceleration can significantly improve compression performance.</p>
