摘 要：随着云计算的快速发展，多租户云数据库成为支持弹性扩展和资源共享的重要基础设施，但资源竞争和性能干扰问题日益突出，严重影响服务质量。为此，本文旨在设计一种面向多租户云数据库的资源隔离与性能保障机制，以实现高效资源管理及稳定的服务性能。研究通过构建细粒度资源分配模型，结合动态监控与预测算法，提出了一种基于优先级调度和自适应调整的隔离策略，有效缓解了租户间资源争用现象。实验结果表明，该机制能够显著降低性能波动，提升系统吞吐量约30%，同时确保高优先级任务的响应时间稳定性。此外，本文创新性地引入了机器学习方法优化资源分配决策，进一步增强了系统的智能化水平和适应能力。研究成果为多租户云数据库的性能优化提供了新思路，并在实际部署中展现出良好的可行性和优越性。

Abstract：With the rapid development of cloud computing, multi-tenant cloud databases have become a critical infrastructure for supporting elastic scaling and resource sharing; however, issues related to resource contention and performance interference have become increasingly prominent, severely affecting service quality. To address this challenge, this study aims to design a resource isolation and performance guarantee mechanism tailored for multi-tenant cloud databases, enabling efficient resource management and stable service performance. By constructing a fine-grained resource allocation model integrated with dynamic monitoring and prediction algorithms, a priority-based scheduling and adaptive adjustment isolation strategy is proposed, effectively mitigating resource contention among tenants. Experimental results demonstrate that the mechanism significantly reduces performance fluctuations and enhances system throughput by approximately 30%, while ensuring the response time stability of high-priority tasks. Furthermore, this research innovatively incorporates machine learning methods to optimize resource allocation decisions, thereby enhancing the system's intelligence and adaptability. The findings provide new insights into performance optimization for multi-tenant cloud databases and exhibit excellent feasibility and superiority in practical deployment.
