This research paper explains how cloud infrastructure can be designed to support community-driven data sharing, where multiple organizations with similar goals collaborate while maintaining data security and sovereignty. It discusses the architectural components of cloud systems, including frontend, backend, and infrastructure layers, and analyzes deployment models such as hybrid, private, multi-cloud, and public clouds. The paper highlights key benefits like cost savings, improved security, regulatory compliance, scalability, and innovation. It also addresses challenges such as governance complexity, interoperability issues, internet dependency, and proper resource allocation. Overall, the study concludes that scalable cloud architecture and service models like IaaS, PaaS, and SaaS make community-based data sharing more efficient, secure, and collaborative
