Recent research in scaling of cloud resources focuses on developing intelligent and adaptive strategies to dynamically adjust computational, storage, and network resources based on fluctuating workload demands. Modern approaches leverage machine learning, predictive analytics, and real-time monitoring to enable proactive scaling decisions that balance cost, performance, and energy efficiency. Techniques such as vertical and horizontal scaling are optimized through automated frameworks that anticipate usage patterns and adjust resource capacity accordingly. These advancements ensure better Quality of Service (QoS), reduced operational overhead, and improved system resilience, making resource scaling a critical component for efficient and sustainable cloud infrastructure management.
