Cloud-Based Database Management: Architecture, Security, challenges and solutions

Abstract

The rapid evolution of cloud computing has revolutionized database management, offering scalable, flexible, and cost-effective solutions for managing large volumes of data. Cloud computing has transformed database management by providing scalable, flexible, and cost-effective solutions for handling massive volumes of data. Cloud-Based Database Management Systems (CDBMS) eliminate the need for extensive on-premise infrastructure, enabling organizations to focus on core operations. These systems leverage advanced architectures, including layered designs that enhance scalability, interoperability, and fault tolerance, ensuring efficient data management. However, adopting cloud databases brings significant challenges, such as data security, multi-tenancy vulnerabilities, and achieving seamless scalability. This paper examines the architecture of CDBMS, highlighting its modular components and their role in maintaining data integrity, access control, and availability. Security challenges, including authentication, encryption, and misconfigurations, are analyzed alongside their implications for data privacy and operational resilience. Emerging solutions such as AI-driven database technologies, edge computing integration, and hybrid cloud strategies are explored to address these challenges. Additionally, the study evaluates the growing role of automation and orchestration tools in optimizing cloud operations by providing a comprehensive review of CDBMS architecture, security concerns, and innovative solutions.
