Product overview
Cloud Storage Private (CSP) is an object storage service provided by Tencent Cloud Enterprise. CSP on CDZ is dedicated for CDZ users.
The infrastructure resources that CSP on CDZ relies on are deployed in the CDZ, and connected to the nearest Tencent Cloud public region via Direct Connect. All data is stored in the CDZ, which can meet data compliance requirements, and also greatly reduce access latency and improve data read/write performance. Users can manage CSP on CDZ in the console, create and delete storage buckets, and perform other configuration management. The user experience is the same as on the public cloud.
Use limits
CSP on CDZ runs in users' CDZs, while COS runs on Tencent Cloud public infrastructures. Due to the difference in operating environments, some COS features are not available on CSP on CDZ.
Uploading and downloading objects in the console is not supported.
Only STANDARD storage is supported. STANDARD_IA and ARCHIVE storage are not supported
Static website hosting is not supported.
It cannot be set as the origin for origin-pull.
Temporary link access is not supported.
Server encryption is not supported.
Object tagging is not supported.
Anti-hotlinking and CORS are not supported.
Bucket replication is not supported.
Domain name transfer and management are not supported.
Most of the features related with other Tencent Cloud products are not supported:
Log management is not supported.
Chinese characters are not supported.`
Data processing is not supported.
Data workflow is not supported.
Function computing is not supported.
File system gateway is not supported.
The performance of CSP on CDZ is also relatively lower than COS on the public cloud. The performance of CSP on CDZ is affected by the scale of the local cluster. In addition, CAM authentication is required for all object storage-related operations. This brings additional network latency. For example, in a typical CSP on CDZ cluster with 3 storage nodes, the expected performance of CSP on CDZ is 1,000 QPS (in small file scenarios) or 500 MB/s (in large file scenarios), which is lower than 30,000 QPS or 15 Gbit/s for a single barrel on the public cloud.
Product billing
The default specification of CSP on CDZ is 120 TB, with a default increment of 40 TB. It can also be configured on demand. This is a prepaid service. Tencent Cloud will underwrite the order based on the demanded storage capacity. After that, we will start deploying services according to your order.
Item | Cycle | Mode | Calculation |
Storage | Monthly | Pay-as-you-go | - Monthly - Storage usage fee =Avg. daily storage usage of the month * Storage unit price - Avg. daily storage usage of the month = Sum of Daily storage usage in the month / Number of days in the month- Daily storage usage = Average of the 288 samples collected every 5 minutes |
Read/write requests | Monthly | Pay-as-you-go | - Number of total requests sent in the month.- Both succeeded and failed requests are billed.- Number of requests is counted in 10K. |
Traffic (Public) | Monthly | Pay-as-you-go | - Data transferred from COS to the user's local device or client over the internet.- Pay-as-you-go: Downstream traffic from the internet (in GB) x Unit price per GB |
Purchase guide
CDZs are not open for purchase online. To set up a CDZ, please contact your sales representative.
Usage guide
Configuration: The console of CSP on CDZ is integrated into the OS console. You can select a dedicated cluster in the CDZ in the COS console, and create, delete or configure storage buckets. The usage is exactly the same as that of COS.
Data read/write: Accessing data on CSP on CDZ is consistent with that on COS. CSP on CDZ is fully compatible with the APIs and SDKs of COS. Note that when accessing CSP on CDZ, you need to specify the CDZ name where the CSP on CDZ is located, and splice it into the Region field. For example, the access address of a COS bucket is generally
<BucketName-APPID>.cos.<Region>.myqcloud.com, and if you access the CSP on CDZ, the bucket address will be<BucketName-APPID>.<CDZ-Zone-name>.cos-cdz.<Region>.myqcloud.com, where cdz-zone-name is the unique identifier of a CDZ.
