In ApsaraMQ for RabbitMQ, an instance is an independent entity that includes basic resources such as virtual hosts (vhosts), exchanges, and queues. An instance can be considered as an isolated server or service environment in which messages are received, stored, and delivered. This topic describes how to create an instance, view instance details, upgrade and downgrade instance configurations, and renew an instance in the ApsaraMQ for RabbitMQ console.
Instance status
The status of ApsaraMQ for RabbitMQ instances varies based on the billing method and instance type.

ApsaraMQ for RabbitMQ provides various types of instances. For information about the differences among the instance types, see Instance types. Note Serverless ApsaraMQ for RabbitMQ instances are available only in specific regions. For more information, see Supported regions. If you want to purchase a serverless instance in a region other than the preceding regions, submit a ticket to contact ApsaraMQ for RabbitMQ technical support. | |
You can view the basic information, endpoints, and usage limits of an instance in the ApsaraMQ for RabbitMQ console. You can also query messages and the peak transactions per second (TPS) of an instance in the ApsaraMQ for RabbitMQ console. Note You can view the peak TPS of an instance only if the message trace feature is enabled for the instance. | |
You can upgrade or downgrade the following configuration items of subscription instances:
You can upgrade or downgrade the following configuration items of serverless instances:

If an instance is released due to overdue payments, the service becomes unavailable and your business is interrupted. To prevent the issue, renew the instance at the earliest opportunity. Note

Note Only subscription instances support the elastic TPS feature. Elastic TPS is the TPS that exceeds the specification limit of an instance. If your actual TPS usage may exceed the specification limit of your instance due to bursty traffic, you can enable the elastic TPS feature to increase the peak TPS of your instance within a specific range. This prevents business interruption that is caused by instance throttling. You are charged for elastic TPS. For information about the upper limits and billing rules of elastic TPS, see Billing of elastic TPS. |

Upgrade or downgrade instance configurations
Usage notes
You can upgrade or downgrade only the configurations of instances that are in the Running state.
In ApsaraMQ for RabbitMQ, Professional Edition and Enterprise Edition instances are of the shared cluster type, and Enterprise Platinum Edition instances are of the dedicated cluster type. When you upgrade a Professional Edition or Enterprise Edition instance to an Enterprise Platinum Edition instance, the instance is migrated between clusters. The migration requires approximately 30 to 60 minutes to complete. The migration duration varies based on the number of queues and the migrated data volume.
When you upgrade a Professional Edition or Enterprise Edition instance to an Enterprise Platinum Edition instance, the endpoint of the instance is not changed and client connections are not forcibly closed. However, the metadata of the instance is migrated. To shorten the upgrade time in the backend, we recommend that you upgrade instance configurations during off-peak hours.
If an instance upgrade or downgrade is not completed after a long period of time and a message that indicates data is being migrated is displayed for specific operations, the data in a specific queue may not be fully consumed. In this case, you can reduce the number of produced messages in the queue or increase the number of consumers.
If you downgrade an Enterprise Platinum Edition instance to a Professional Edition or Enterprise Edition instance, instance data is not migrated and your business is not affected.
You cannot upgrade a serverless instance to other instance types.
