云计算环境下的多租户数据库管理技术 -计算机科学与技术专业

摘要

随着云计算技术的快速发展，多租户数据库管理系统已成为支撑大规模SaaS应用的关键技术。本研究针对传统多租户数据库在资源隔离、性能优化和安全管理等方面存在的不足，提出了一种基于虚拟化技术的多租户数据库管理架构。该架构采用轻量级容器技术实现租户间的资源隔离，通过动态资源分配算法优化系统性能，并设计了细粒度的访问控制机制保障数据安全。研究过程中构建了原型系统进行实验验证，结果表明所提出的方法在并发处理能力上较传统方案提升约35%，资源利用率提高28%，同时有效降低了跨租户数据泄露风险。本研究的创新点在于将虚拟化技术与数据库管理系统深度结合，实现了更高效的资源管理和更强的安全防护。研究成果为云计算环境下多租户数据库系统的设计与优化提供了新的思路和方法，对推动SaaS应用的规模化发展具有重要实践意义。

MULTI-TENANT DATABASE MANAGEMENT TECHNOLOGY IN CLOUD COMPUTING ENVIRONMENT

ABSTRACT

With the rapid development of cloud computing technology, multi-tenant database management system has become a key technology to support large-scale SaaS applications. Aiming at the shortcomings of traditional multi-tenant database in resource isolation, performance optimization and security management, this paper proposes a multi-tenant database management architecture based on virtualization technology. The architecture uses lightweight container technology to realize resource isolation among tenants, optimizes system performance through dynamic resource allocation algorithm, and designs a fine-grained access control mechanism to ensure data security. During the research, a prototype system was constructed for experimental verification, and the results showed that the proposed method improved the concurrent processing capacity by about 35% and resource utilization by 28% compared with the traditional scheme, and effectively reduced the risk of cross-tenant data leakage. The innovation of this research lies in the deep combination of virtualization technology and database management system to achieve more efficient resource management and stronger security protection. The research results provide new ideas and methods for the design and optimization of multi-tenant database system under cloud computing environment, and have important practical significance for promoting the scale development of SaaS applications.
