Use Strengths
Integrated Management
- CFS can provide POSIX file system access semantics (such as strong data consistency and file locking). CVM instances of the cloud platform can use standard operating system mounting commands to mount CFS through the NFS v3.0/v4.0 protocol.
- CFS offers a console interface, allowing you to create and configure file systems quickly and easily, and saving the complexity of deploying and maintaining file systems.
Automatic Scaling
CFS can automatically scale out the storage capacity of a file system according to the size of the file capacity without interrupting requests and applications, ensuring exclusive access to the required storage resources, while reducing the time cost and workload of management.
Security and Reliability
- CFS adopts a three-replica distributed storage mechanism, delivering extremely high reliability. The system returns a response of successful writing only after confirming that the data has been written to all the three replicas. The backend data replication mechanism can quickly create a replica through data migration and other methods when any one of the replicas fails, so as to ensure that three replicas are always available and provide you with secure and reliable data storage services. CFS stores data across racks, with a reliability of 99.9999999% (nine 9s).
- CFS strictly controls the access permissions for a file system by combining security groups of basic networks or VPC networks with permission groups.
Low Costs
- CFS can dynamically adjust the required capacity, so that you do not need to adjust it in advance but pay by usage, with no minimum consumption threshold, deployment fees, or Ops fees involved.
- Multiple compute nodes can share the same storage space through the NFS protocol, so that you do not need to purchase other storage services again or consider a cache.
