Billing

DMS for Kafka supports pay-per-use. For details, see Pricing Details.

Billing Items

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

Table 1 DMS for Kafka billing

Billing Item

Description

Instance
  • Kafka instances are billed based on their ECS flavor and broker quantity. When purchasing an instance, select appropriate ECS flavors and the number of brokers based on service evaluation. Table 2 lists the performance per broker.

Storage space
  • Instances are 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. For example, if the disk size required to store message data is 500 GB and there are three replicas, the disk capacity should be at least: 500 GB x 3 = 1500 GB.

  • Storage space can be specified with increments of 100 GB. For details about the storage space range, see Table 2.
