The rapid advancement of Information and Communication Technology (ICT) has fundamentally transformed Library and Information Science, with traditional libraries evolving from mere repositories of printed materials into digital, network-enabled, and user-centric knowledge management environments. Within this context, cloud computing has emerged as a pivotal technological framework, enabling libraries to manage information storage, processing, access, and dissemination efficiently, securely, and cost- effectively. By reducing reliance on local hardware, software, and maintenance, cloud- based services allow even small and medium-sized libraries to provide advanced digital services without substantial infrastructural investment. Simultaneously, global data sharing has facilitated seamless, rapid, and effective exchange of information resources among libraries, research institutions, and academic centers across countries, with open access initiatives, digital repositories, cloud-enabled cataloguing, and shared information infrastructures strengthening international collaboration in research and learning. This study critically examines the concept, classification, operational models, advantages, limitations, and significance of cloud-based library services in global data sharing, employing a descriptive research methodology and a comprehensive review of scholarly articles, journals, institutional reports, electronic resources, and publications by professional bodies such as IFLA. The findings indicate that cloud-based services enhance efficiency, accessibility, user orientation, and collaboration, while enabling optimized reuse of resources, cost and time savings, and improved service quality; however, challenges including data security, privacy, intellectual property rights, legal compliance, technological dependence, and internet infrastructure limitations remain significant. The study concludes that with clear policies, adherence to international standards, robust security frameworks, legal clarity, and continuous technical training of library professionals, cloud-based library services and global data sharing can form the foundational elements of future digital library ecosystems, making their integration essential for modern library management in the digital era.
