:original_name: cce_10_0307.html .. _cce_10_0307: Overview ======== Container Storage ----------------- CCE container storage is implemented based on Kubernetes container storage APIs (:ref:`CSI `). CCE integrates multiple types of cloud storage and covers different application scenarios. CCE is fully compatible with Kubernetes native storage services, such as emptyDir, hostPath, secret, and ConfigMap. .. figure:: /_static/images/en-us_image_0000001647576484.png :alt: **Figure 1** Container storage type **Figure 1** Container storage type CCE allows you to mount cloud storage volumes to your pods. Their features are described below. .. table:: **Table 1** Cloud storage comparison +----------------------+-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+ | Dimension | EVS | SFS | SFS Turbo | OBS | +======================+=======================================================================================================================================================================================================================================================================+========================================================================================================================================================================================================================================+================================================================================================================================================================================================================================================================================================================================================+========================================================================================================================================================================================================================================================+ | Definition | EVS offers scalable block storage for cloud servers. With high reliability, high performance, and rich specifications, EVS disks can be used for distributed file systems, dev/test environments, data warehouses, and high-performance computing (HPC) applications. | Expandable to petabytes, SFS provides fully hosted shared file storage, highly available and stable to handle data- and bandwidth-intensive applications in HPC, media processing, file sharing, content management, and web services. | Expandable to 320 TB, SFS Turbo provides a fully hosted shared file storage, which is highly available and stable, to support small files and applications requiring low latency and high IOPS. You can use SFS Turbo in high-traffic websites, log storage, compression/decompression, DevOps, enterprise OA, and containerized applications. | Object Storage Service (OBS) provides massive, secure, and cost-effective data storage for you to store data of any type and size. You can use it in enterprise backup/archiving, video on demand (VoD), video surveillance, and many other scenarios. | +----------------------+-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+ | Data storage logic | Stores binary data and cannot directly store files. To store files, format the file system first. | Stores files and sorts and displays data in the hierarchy of files and folders. | Stores files and sorts and displays data in the hierarchy of files and folders. | Stores objects. Files directly stored automatically generate the system metadata, which can also be customized by users. | +----------------------+-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+ | Access mode | Accessible only after being mounted to ECSs or BMSs and initialized. | Mounted to ECSs or BMSs using network protocols. A network address must be specified or mapped to a local directory for access. | Supports the Network File System (NFS) protocol (NFSv3 only). You can seamlessly integrate existing applications and tools with SFS Turbo. | Accessible through the Internet or Direct Connect (DC). Specify the bucket address and use transmission protocols such as HTTP or HTTPS. | +----------------------+-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+ | Static provisioning | Supported.
