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 with scalable capacity and performance.
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.
CFS provides a simple, easy-to-learn console interface. You can quickly create, configure and manage the file system, and reduce the amount of time you spend deploying and maintaining your own Network Attached storage (NAS).
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.
CFS storage capacity scales flexibly without impacting applications or services. At the same time, performance increases in line with storage to provide reliable, high-performance services.
CFS assigns capacity dynamically and prepayment is not required. Billing is based on actual usage. Because CFS can be accessed by multiple clients, there is no need to purchase other storage solutions.
CFS standard file storage runs with three layers of redundancy giving extremely high availability and reliability. CFS can restrict client permissions using user isolation, network isolation and access whitelists.
CFS supports NFS v3.0/4.0 protocols and POSIX APIs, allowing you to run NFS commands to use file systems.
CFS can be easily managed either in the console or via APIs, enabling you to create and configure file systems conveniently. There is no need for complex deployments or maintenance.
A file system can be accessed and used in three simple steps:
1. Create a file system and obtain the mount point
2. Start the NFS client on the server
3. Mount the created file system
Compute nodes such as CVM instances and containers can share the same storage space via the NFS protocol, eliminating the need of data synchronization. Different deployment schemes can be used to access files across availability zones and networks based on your actual business needs.
CFS can automatically expand the storage capacity of a file system based on inbound data size. In such cases, the file system throughput will be automatically increased too, so that your application can get the required storage capacity and performance in a timely manner to ensure business continuity.
CFS supports permission management through CAM, so you can manage CFS resource permissions with authorizations from a root account. As to file system permissions, it supports network isolation among VPCs and allows you to configure permission groups for access control over file systems.
In companies with a large number of employees, people need to share and have access to the same datasets. Administrators can use CFS to create a file system and allow the access of individuals in organizations. And administrators can also set file or directory-based permissions for users or user groups.
Shared file storage is often relied upon to handle the large files required by multimedia tasks such as video editing, AV production, broadcast processing, sound design and rendering. CFS’s powerful data consistency model coupled with high throughput and shared data access can reduce the time needed to process multimedia files.
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 applications or services such as websites, online publishing, and resource archiving.
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 suitable for carrying out data analysis and logset processing coupled with data analysis services and container services.
Tencent Cloud CFSs are billed in a postpaid manner. In this flexible billing mode, you can only pay for what you use. Billing and settlement is performed hourly, and you don't need to pay for anything in advance. View more.
