Getting Started Overview

Updated at：2025-11-11

This document explains the complete process from creating to using a CFS file system, allowing you to quickly get started with Cloud File System (CFS).

CFS overview

Baidu AI Cloud File System (CFS) is a secure and efficient file storage service. It enables file storage and sharing across operating systems for virtual machines and container resources on the cloud. CFS works seamlessly with native operating systems via the POSIX API and is compatible with NFS and SMB protocols. Additionally, Baidu AI Cloud CFS offers simple and user-friendly external interfaces, supports pay-as-you-go billing, eliminates deployment and maintenance costs, and maximizes business efficiency.

  • Basic Concepts: Understand fundamental concepts encountered when using Cloud File System (CFS).
  • Product Features: Understand the features of Cloud File System (CFS).
  • Product Specifications: Cloud File System (CFS) offers performance and capacity storage classes, which are selectable per service needs.
  • Usage Restrictions: Understand Cloud File System (CFS) usage restrictions.
  • Application Scenarios: Understand the diverse application scenarios of Cloud File System (CFS)
  • How to Select CFS and PFS, How to Select CFS, BOS, and CDS: Select the appropriate Baidu AI Cloud storage services based on actual service needs.

Charge type

Cloud File System (CFS) uses a pay-as-you-go model by default, but it also supports subscription-based (storage package) payments.

Charge type
 Description
Pay-as-you-go The pay-as-you-go model enables you to use services first and pay afterward, making it ideal for scenarios with frequent usage fluctuations.
Storage package billing You can pre-purchase discounted storage packages for file systems of different configurations. When billing, your usage will first be deducted from the storage package, and the deducted amount will not appear on your pay-as-you-go bill. This approach is suitable for scenarios with relatively stable usage patterns.
