Which protocol is commonly used for cloud storage integration?

NFS, or Network File System, is commonly used for cloud storage integration due to its design that supports seamless access to file-based data across a network. It enables systems to share files and directories in a standardized way, allowing multiple clients to access the same data regardless of their location. This capability is particularly beneficial in cloud environments, where storage can be hosted remotely and accessed by various client systems.

NFS provides the benefits of scalability and flexibility, making it well-suited for cloud applications that require consistent and efficient access to shared data. It allows for easy integration and management of storage resources in a cloud infrastructure, facilitating collaboration among users and applications that need access to large datasets.

In contrast, while protocols like FTP, iSCSI, and SMB serve specific purposes for file transfer, block storage, and Windows-based network sharing respectively, they may not be as optimized for the seamless, scalable access and integration that NFS offers in cloud storage scenarios.
