This thesis focuses on the study of cloud computing, a technology that has fundamentally transformed the way information is delivered, used, and managed. It explores the core characteristics of cloud systems, the service models (SaaS, PaaS, IaaS), the deployment models (Public, Private, Hybrid, Multi-cloud), and analyzes both the advantages and disadvantages of cloud adoption.
Particular emphasis is placed on security challenges, privacy protection, regulatory compliance, and cost management. Furthermore, the study examines current trends, emerging technologies, and security frameworks that support data integrity and resilience. Through this research, the importance of cloud computing for business evolution and technological innovation is highlighted. Although the technology presents risks, it also offers significant opportunities for flexibility, innovation, and sustainable development.
