Cloud File Storage

A secure, scalable and low-cost file sharing solution


Cloud File Storage (CFS) is a secure and scalable file sharing and storage solution. It can be used in conjunction with Tencent Cloud's servers, container service, and batch computing service. CFS provides multiple computing nodes with high-performance shared storage featuring scalable capacity and performance.


Integrated Management

CFS is compatible with POSIX and supports cross-platform access, ensuring the consistency of files and data. Your Cloud Virtual Machine (CVM) instance can access the CFS system using the standard NFS protocol.

Easy to Use

CFS provides a simple and easy-to-learn console interface. Using CFS, you can quickly create, configure and manage a file system, reducing the amount of time spent deploying and maintaining your own network-attached storage (NAS).

Shared Access

Multiple CVMs or container services can share the same CFS system. Computing nodes in different regions can also use the same CFS through a VPC, allowing multiple nodes to coordinate tasks and share files.

Flexible and Scalable

CFS storage capacity scales flexibly without impacting your applications or services. CFS performance increases in accordance with storage size to provide reliable and high-performance services.


CFS dynamically assigns capacity, does not require upfront payments, and is pay-as-you-go. Because CFS can be accessed by multiple clients, you do not need to purchase other storage solutions.

Secure and Reliable

CFS standard file storage runs with three layers of redundancy and features extremely high availability and reliability. CFS can restrict client permissions using user isolation, network isolation and access allowlists.


CFS supports NFS semantics and provides a wide variety of file storage features such as permission management.
NFS Protocols

CFS supports NFS v3.0/4.0 protocols and POSIX APIs, allowing you to run NFS commands to use file systems.


Corporate File Sharing

In large companies, employees need to share and have access to the same datasets. Using CFS, administrators can create a file system and grant access to individual employees. Administrators can also set file or directory-based permissions for users or user groups.

Streaming Media

Multimedia tasks such as video editing, AV production, broadcast processing, sound design and rendering often rely on shared file storage to handle large files. Coupled with high throughput and shared data access, CFS’s powerful data consistency model can reduce the time needed to process multimedia files.

Web Services and Content Management

CFS is a highly compatible and durable file system. It can be used for a range of content management systems and to provide data source files for application services such as websites, online publishing and resource archiving.

Big Data Analysis

CFS provides the scale and performance required for big data applications. With high-throughput computing nodes, read-after-write consistency and low latency, CFS is particularly well-suited to perform data analysis and logset processing.
