This document describes the billing mode and billable items of TDMQ for RocketMQ exclusive cluster.
Available Regions
Exclusive cluster is currently supported in the following regions:
Region | Code |
Guangzhou | ap-guangzhou |
Shanghai | ap-shanghai |
Nanjing | ap-nanjing |
Beijing | ap-beijing |
Singapore | ap-singapore |
Virginia | na-ashburn |
Silicon Valley | na-siliconvalley |
Hong Kong (China) | ap-hongkong |
Billing Mode
Item | Billing Mode | Description |
Cluster instance | Monthly subscription – prepaid | When you purchase an exclusive cluster, the system will calculate the fees based on the cluster specification and service duration you select. You need to make upfront payment before using the cluster. This billing mode is suitable for long-term services with a relatively stable business traffic peak. |
Public network bandwidth | Bill-by-hour bandwidth – postpaid | You are charged hourly for your actual public network bandwidth usage duration on a pay-as-you-go basis. This billing mode is suitable for short-term services with a relatively stable business traffic peak. |
Cluster Instance Pricing
Billable items
TDMQ for RocketMQ exclusive cluster fees are calculated as follows:
Cluster price = minimum configuration price + compute configuration price + storage configuration price = minimum configuration price + node unit price number of nodes + storage unit price storage size.
Billable Item | Description |
Minimum configuration | It refers to the fixed fees of a new cluster for basic services such as cluster management, message management, observability, and high availability, which will not increase as the cluster size increases. |
Compute configuration | It refers to the compute service fees. Various node specifications are provided on demand. The price of a single node of each specification is fixed, and there are restrictions on the numbers of minimum and maximum nodes. The compute configuration price changes linearly based on the number of nodes. |
Storage configuration | It refers to the storage service fees. You can customize the storage space in increments of 100 GB. The storage configuration price changes linearly based on the storage size. |
Pricing
The specific price is as displayed on the purchase page. This section describes the performance differences between exclusive cluster specifications.
Note
If the number of nodes in current specifications cannot meet your business requirements, submit a ticket for assistance.
Minimum configuration
The performance of the following specification is a reference value. The actual performance won't be any worse given the data measured during stress tests. Unexpected elastic capacity outside the specification won't cost anything either.
The calculation rules are the same for TPS and the number of API calls of virtual clusters.
Message type: TDMQ for RocketMQ has four message types: general message, scheduled and delayed message, transactional message, and sequential message. Except general messages, the other three message types are advanced messages.
Sending or consuming one general message is counted as 1 TPS, while sending or consuming one advanced message (such as a delayed or transactional message) is counted as 5 TPS. For example, if a topic sends two transactional messages once and consumes one transactional message, the TPS will be 15 (2×5+1×5=15).
Message size: The maximum size of a single message is 4 MB, with 4 KB as the unit of measurement. A size of less than 4 KB is calculated as 4 KB.
Specification Type | Single-Node Specification |
Basic | TPS (production + consumption): 2,000 |
Standard | TPS (production + consumption): 5,000 |
Advanced I | TPS (production + consumption): 10,000 |
Advanced II | TPS (production + consumption): 18,000 |
Compute configuration
Compute configuration fees = node price * number of nodes
Cluster performance description: The cluster performance is equal to node performance * number of nodes and it changes linearly within the node range.
Specification Type | Minimum Nodes | Maximum Nodes | Minimum Single-Node TPS (in units of 4 KB) |
Basic | 2 | 10 | 2,000 |
Standard | 2 | 10 | 5,000 |
Advanced I | 2 | 20 | 10,000 |
Advanced II | 2 | 20 | 18,000 |
Storage configuration
Storage fees = storage space * storage unit price.
Each exclusive cluster version provides a minimum storage of 200 GB for a single node. You can choose a higher storage space in increments of 100 GB based on your business needs.
Public Network Bandwidth Price
Fees are charged hourly by the actual number of usage hours based on the public network bandwidth in Mbps.
Region | Price (USD/Mbps/Hour) | |
| 1–5 Mbps | 6 Mbps or above |
Guangzhou, Shanghai, Nanjing, Beijing | 0.04 | 0.14 |
Singapore | 0.035 | 0.12 |
Yes
