This topic describes the types and editions of ApsaraMQ for RocketMQ instances and the differences among these instance types and editions. This topic also describes the specifications of each instance edition, including the computing specification, Internet bandwidth, and resource quotas. You can refer to the description in this topic to purchase an instance that meets your business requirements.
Billing methods
Billing method | Description | Scenario | Supported instance edition |
Subscription | You can use an instance only after you pay the computing fees based on the selected computing specification and subscription duration. You are charged for other resources on the instance based on the actual usage. | This billing method is suitable for scenarios in which the amount of traffic is large and stable. |
|
Pay-as-you-go | Computing fees are generated based on the selected computing specification and service duration of an instance after the instance is created. A bill is generated and fees are deducted from your Alibaba Cloud account every hour. You are charged for other resources on the instance based on the actual usage. | This billing method is suitable for test and short-term activity scenarios, such as special marketing activities and end-to-end stress testing activities that require timeliness. If you want to continue using a pay-as-you-go instance after the test or short-term activity is complete, you can change the billing method of the instance to subscription. For more information, see Change the billing method of an instance from pay-as-you-go to subscription. |
|
Serverless | You are charged for resources based on the actual usage. Bills are generated and fees are deducted from your Alibaba Cloud account after the billing cycle (1 hour) ends. | This billing method is suitable for scenarios in which traffic greatly fluctuates or capacity is difficult to evaluate. |

Specification limits
Standard Edition instances and Professional Edition Standalone instances do not support the scaling of computing resources. We recommend that you plan your resource usage to prevent instance throttling caused by traffic that exceeds the specification limit.
The topic and consumer group quotas of an instance are calculated based on actual use cases in large-scale production environments. In most cases, these quotas can meet your business requirements. We recommend that you use different topics and consumer groups for different departments and applications. Do not run all your business in one instance.
Messaging TPS is the total number of times that messages can be sent and received. Messaging TPS is calculated based on a normal message whose size is 4 KB. Multiples must be used when you calculate the TPS for featured messages and large messages. For information about the calculation methods, see Computing specifications.
The following items describe what happens if the actual messaging TPS exceeds the specification limit:
If you enable the elastic TPS feature for an instance and the excess TPS that you use does not exceed the upper limit that is specified by the elastic TPS feature, the instance runs as expected. You are charged for the excess TPS based on a pay-as-you-go basis. If the excess TPS that you use exceeds the upper limit that is specified by the elastic TPS feature, the instance is throttled.
For information about the billing rules of the elastic TPS feature, see Elastic TPS fee.
If the elastic TPS feature is not supported by or enabled for an ApsaraMQ for RocketMQ instance, the instance is throttled.
If a large number of clients are connected to an ApsaraMQ for RocketMQ instance, the broker consumes a large number of resources to maintain the connections. This compromises the stability of the broker. We recommend that the number of connections to an ApsaraMQ for RocketMQ instance does not exceed the specification limit.
