Abstract
With the rapid development of cloud computing technology, the effective allocation and utilization of cloud platform resources has become a key problem to be solved urgently. As a core technology to improve the quality of cloud services and optimize resource utilization, load balancing is becoming increasingly important. This study focuses on load balancing technology in cloud computing platforms, aiming to explore more efficient and intelligent load balancing strategies to cope with complex and changeable application scenarios. By analyzing the limitations of the existing algorithm in the dynamic environment, we propose a hybrid load balancing algorithm based on the adaptive feedback mechanism, which integrates the advantages of static estimation and dynamic adjustment, and can realize the optimal allocation of resources on the premise of ensuring the stability of the system. The experimental results show that the proposed algorithm reduces on average by 25% and improves resource utilization by 18% in response time compared to the traditional method. In addition, to meet the special needs of large-scale distributed systems, the machine learning model is introduced to predict the traffic, which further enhances the adaptive capability of the system.
