ApsaraMQ for MQTT uses instances to host messaging services and store your topics and groups. Each instance runs on a dedicated virtual machine and is billed on a subscription (prepaid) basis. Two editions are available: Standard Edition and Enterprise Platinum Edition.
For edition differences and feature comparisons, see Instance editions.
For instance-related limits, see Instances.
