Overview

CFS is compatible with the POSIX interface by supporting the standard NFS protocol. Thus, it ensures that the CVM and container resources can operate the cloud system, like the local file system, and realize the cross-node data sharing and collaboration. Furthermore, CFS provides the simple and easy-to-operate external interface, and supports the bill-by-actual usage capacity, to eliminate the deployment and maintenance cost, and maximize your business efficiency.

Features

Seamless Integration

CFS supports the standard NFS V4.1 protocol. Users can mount instances on the POSIX interface using the standard operating system mount command.

Shared Access

To realize the shared storage and efficient sharing of files, multiple computing resources can mount the same file system simultaneously.

Elastic expansion

CFS provides the Scale-Out capability, and the single file system supports up to 100PB and 1 billion files.

Full Hosting

CFS provides the simple API interface and Web console, facilitating users to create and manage the file system, and save the local construction and operations cost.

Content Management and Web Application
In large-scale websites, games, videos and other fields, content is often provided by server clusters. When each BCC needs to access the same group of files, it can mount the same CFS to read/write the same files. The high scalability and availability of CFS can meet the requirements for the high IO read/write of front-end servers. Be applicable to Portals, WEB Applications, and Smartphone APPs.
Big Data Analysis
CFS meets the requirements of high throughput, read-after-write consistency, and low delay for typical big data applications in the computing node, and provides the file-sharing solution which is easy to integrate into the big data workflow. Be applicable to Internet Applications and Big Data Analysis.
Pan-entertainment and Media Application
In such scenarios as post-production of audio and video, broadcast media processing and rendering, a typical feature is that the files to be processed are large, and multiple servers work together to process the files. CFS can provides the ability of quick shared access to large files. Be applicable to LVB platforms and media resource processing software.
Enterprise Office File Sharing
Inside the enterprise, employees need access to the same file in the enterprise document system from different terminals. The administrator can mount each enterprise office system to the CFS, and provide the enterprise with a unified and shared operating system. Be applicable for manufacturing, government, and finance sectors.
