Monthly Subscription
마지막 업데이트 시간:2025-03-11 11:51:29
Monthly subscription is a prepaid billing method that allows you to use resources after payment. It is mainly applicable for business scenarios with stable and long-term usage. Before purchasing, you need to estimate the performance requirements of your business, such as peak bandwidth, number of partitions, and disk capacity. You pay for one month, multiple months, or multiple years in advance. Once payment is successful, the resources are allocated by the system. If the resources are not renewed after the validity period, they will be reclaimed.
This document mainly introduces the billing items, billing formula, and pricing of TDMQ for CKafka under the monthly subscription billing mode.
Note:
For differences between the Standard and Professional Edition instance specifications, see Product Specifications.
Billing Items
Item | Professional Edition | Advanced Edition | Description |
Peak bandwidth | ✓ | ✓ | Throughput refers to the peak of outbound or inbound bandwidth. When you purchase, choose the private network bandwidth based on the maximum of either the outbound or inbound peak bandwidth. Taking the number of instance replicas into consideration, the throughput needs to be distributed evenly. For example, if a customer requires 40 MB of throughput and there are 3 replicas, 120 MB/s of throughput bandwidth needs to be purchased. |
Disk capacity | ✓ | ✓ | Different instance specifications correspond to different disk capacities. Supported disk types are Cloud SSD and Premium Cloud Disk. |
Partition | ✓ | ✓ | Different instance specifications correspond to different numbers of partitions. Partitions for the Professional Edition can be purchased separately. The maximum number of topics that can be used = Number of partitions/Number of replicas. Reducing the number of partitions is not supported. Instance-level partition limitations include the number of replicas. For example, if an instance has 1 topic with 2 replicas and 4 partitions, and 2 topics with 3 replicas and 3 partitions, the total number of partitions for that instance is (1 x 2 x 4) + (2 x 3 x 3) = 26 partitions. |
Billing Formula
CKafka is sold in the form of instances. The billing formula for the monthly subscription mode is as follows:
When purchasing Advanced and Professional Edition instances, you need to estimate your business peak bandwidth, number of partitions, and disk capacity. Total cost of the purchased instances = (Basic package fee + Partition package unit price x Additional partition quantity / 100 + Disk capacity unit price x Disk capacity / 100) x Number of months.
Note:
When creating a topic in CKafka, you can choose between triple-replica storage or dual-replica storage. The actual business storage is the purchased disk space divided by the number of replicas.
For example: When a 300 GB disk is purchased, if dual-replica storage is chosen, the actual disk size of the storage business will be 150 GB; if triple-replica storage is chosen, the actual disk size of the storage service will be 100 GB.
Instance Pricing
Advanced Edition
The CKafka Advanced Edition offers a flexible parameter configuration method, allowing you to purchase and scale out as needed based on your specific business situation.
Basic Package
After you select the peak bandwidth size, it will automatically correspond to a tier of the basic package. Each tier includes a certain number of partitions. Number of available topics in the package = Number of partitions/Number of replicas.
The correspondence between peak bandwidth (x) and the partition specification included in the package is as follows:
Peak Bandwidth Tier (MB/s) | Package Partition Specification |
x = 20 | 400 |
40 ≤ x＜60 | 800 |
60 ≤ x＜120 | 900 |
120 ≤ x＜180 | 1,200 |
180 ≤ x＜240 | 1,400 |
240 ≤ x＜320 | 1,600 |
320 ≤ x ≤ 360 | 1,800 |
Note:
The number of partitions included in the package is covered by the package fee, with no additional charges.
For TDMQ for CKafka instances of higher specifications, contact your business manager or Online Consultation for activation.
The price of the peak bandwidth basic package is billed according to different tiers. The price tiers are as follows:
Peak Bandwidth Range (MB/s) | Price (Monthly Subscription) |
20 | 63.57 USD/month |
40 to 100 | Starting from 142.14 USD/month, the price increases by 7.14 USD/month for every additional 20 MB/s of bandwidth. |
120 to 300 | Starting from 241.21 USD/month, the price increases by 6.43 USD/month for every additional 20 MB/s of bandwidth. |
320 to 360 | Starting from 439.07 USD/month, the price increases by 5.71 USD/month for every additional 20 MB/s of bandwidth. |
Example: For an instance with 180 MB/s, if it increases by 60 MB/s on the basis of 120 MB/s, the package price will be 241.21 + 6.43 x (60 / 20) = 260.5 (USD/month).
Partition Overlay Package Price
After the peak bandwidth size is selected, if the partition specification in the corresponding basic package still does not meet requirements, you can purchase additional partition overlay packages separately. The partition overlay package is added in units of 100 partitions. The partition overlay package price is as follows:
Tier | Number of Partitions per Unit | Unit Price for Partition Packages (Monthly Subscription) |
Any tier | 100 | 28.57 USD/month |
Price for Scaling out Disks
Purchasing CKafka Professional Edition requires the minimum purchase of a certain disk size. Disks are scaled out in units of 100 GB. The disk prices are as follows:
Tier | Disk Type | Disk Capacity per Unit (GB) | Unit Price for Disks (Monthly Subscription) |
Any tier | SSD | 100 | 14.29 USD/month |
Any tier | Premium Cloud Disk | 100 | 5 USD/month |
Professional Edition
CKafka Professional Edition offers flexible parameter configuration method and more stable upgrade capabilities. You can purchase and scale out based on your specific business needs.
Basic Package
After the peak bandwidth size is selected, it will automatically correspond to a tier of the basic package. Each tier includes a certain number of partitions, and topics are no longer charged separately. Number of available topics in the package = Number of partitions / Number of replicas.
The correspondence between the peak bandwidth (x) and the partition specification included in the package is as follows:
Peak Bandwidth Tier (MB/s) | Package Partition Specification |
x = 20 | 400 |
40 ≤ x＜60 | 800 |
60 ≤ x＜120 | 900 |
120 ≤ x＜180 | 1,200 |
180 ≤ x＜240 | 1,400 |
240 ≤ x＜320 | 1,600 |
320 ≤ x＜400 | 1,800 |
400 ≤ x＜500 | 2,000 |
500 ≤ x＜600 | 2,200 |
600 ≤ x＜800 | 2,400 |
800 ≤ x＜1,000 | 2,600 |
1,000 ≤ x＜1,200 | 2,800 |
x = 1,200 | 3,200 |
x = 1,600 | 4,000 |
x = 2,000 | 4,500 |
x = 2,400 | 5,000 |
x = 2,800 | 5,500 |
x ≥ 3,200 | 6,000 |
Note:
The number of partitions included in the package is covered by the package fee, with no additional charges.
For CKafka instances of higher specifications, contact your business manager or Online Consultation for activation.
The price of the peak bandwidth basic package is billed according to different tiers. The price tiers are as follows:
Peak Bandwidth Range (MB/s) | Price (Monthly Subscription) |
20 | 167 USD/month |
40 to 100 | Starting from 360 USD/month, the price increases by 53 USD/month for every additional 20 MB/s of bandwidth. |
120 to 300 | Starting from 630 USD/month, the price increases by 51 USD/month for every additional 20 MB/s of bandwidth. |
320 to 600 | Starting from 1200 USD/month, the price increases by 49 USD/month for every additional 20 MB/s of bandwidth. |
620 to 900 | Starting from 2340 USD/month, the price increases by 43 USD/month for every additional 20 MB/s of bandwidth. |
920 to 1,200 | Starting from 3090 USD/month, the price increases by 34 USD/month for every additional 20 MB/s of bandwidth. |
1,600 to 20,000 | Starting from 4150 USD/month, the price increases by 428 USD/month for every additional 20 MB/s of bandwidth. |
Example: For an instance with 180 MB/s, categorized under 120 to 300, if it increases by 60 MB/s on the basis of 120 MB/s, the package price will be 630 + 51 × ( 60 / 20 ) = 783 (USD/month).
Partition Overlay Package Price
After the peak bandwidth size is selected, if the partition specification in the corresponding basic package still does not meet requirements, you can purchase additional partition overlay packages separately. The partition overlay package is added in units of 100 partitions. The partition overlay package price is as follows:
Tier | Number of Partitions per Unit | Unit Price for Partition Packages (Monthly Subscription) |
