Billing Items

DMS for RabbitMQ is billed based on RabbitMQ instance specifications and storage space.

**Table 1** Billing of DMS for RabbitMQ
Billing Item	Description
Instance	RabbitMQ instances are billed based on the specifications described in Table 2. RabbitMQ instances can be billed on a pay-per-use (hourly) basis.
Storage	RabbitMQ instances are also billed based on the storage space. For each type of instance specification, you can choose the high I/O or ultra-high I/O disk type to meet your service requirements. You can specify the number of replicas when creating a topic. For example, if the required disk size to store the message data is 100 GB and there are three replicas, the disk capacity should be at least: 100 GB x 3 = 300 GB. Storage space can be specified with increments of 100 GB. For details about the storage space range, see Table 2. Storage space can be billed on a pay-per-use (hourly) basis.
