Abstract
With the booming development of cloud computing technology, cloud storage, as one of its core services, poses new challenges to data storage, management and access. Distributed file systems have become a key component of the cloud storage architecture due to their high scalability, high fault tolerance, and good concurrency performance. This paper aims to discuss the design and application of distributed file system in the cloud storage environment. It first summarizes the service model of cloud storage and its basic requirements for storage system, and then analyzes the basic principles and key problems of distributed file system design, including system architecture, me tadata management, data consistency model and fault tolerance mechanism. This paper discusses the practical application of distributed file system in cloud storage platform, and points out the technical difficulties and solution strategies, such as improving data reliability and access speed through data fragmentation and redundant replication. At the same time, combined with specific cases, this paper shows how to optimize the performance of the distributed file system according to different application scenarios to meet the diverse needs of cloud storage services.
