This research aims to design and implement a cloud-based university sports information management and big data service platform to enhance the efficiency and quality of sports information management in higher education institutions. Traditional sports information management relies heavily on manual processes, leading to issues such as low efficiency and data isolation. This platform integrates cloud computing and big data technologies to achieve efficient data processing, secure information storage, and convenient data sharing. The platform's processing capacity has been increased from manually handling a few hundred megabytes of data to automatically processing over 5 gigabytes per day, significantly improving the efficiency of sports information management. Additionally, the introduction of encryption and access control mechanisms effectively ensures data security and privacy protection. Through the application of this platform, not only has the quality of sports teaching and research been improved, but it also provides a digital solution for sports facility management. This platform offers a new perspective and approach to the informatization of sports in higher education institutions, demonstrating the potential of modern technology in sports information management.
