      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
      Standard 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.
      Public network bandwidth
      ✓
      -
      CKafka provides 3 Mbps of free public network bandwidth by default. The Professional Edition instances can additionally upgrade public network bandwidth to a maximum of 198 Mbps.

      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

      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
