What is Alibaba Cloud's solution for shared file storage across multiple users?

Alibaba Cloud NAS (Network Attached Storage) is specifically designed for providing scalable and high-performance shared file storage solutions that can be accessed by multiple users and applications. It serves as a centralized file storage system that allows for easy sharing, collaboration, and management of files across different instances, making it ideal for various workloads that require concurrent access to the same data.

The key features of Alibaba Cloud NAS include its ability to support multiple protocols such as NFS and SMB, which facilitate integration with different operating systems and development environments. This flexibility enables users to seamlessly store and retrieve files, enhancing collaborative efforts among team members or applications that require access to shared datasets.

In contrast, other options like Alibaba Cloud Object Storage Service are geared more toward storing unstructured data in an object format, making them suitable for scenarios like backup and archive rather than real-time shared access. Alibaba Cloud File Storage Gateway acts as a bridge between NAS and object storage but doesn't serve as a standalone shared file storage solution. Similarly, Alibaba Cloud Data Archive Service is focused on long-term data retention rather than multi-user file sharing. Therefore, NAS is the optimal choice for shared file storage across multiple users.
