ApsaraMQ for Kafka:How do I select an instance edition?

Instance type and edition

Traffic specification

Disk size

Partition count

Non-serverless instances

Standard Edition (High Write)

• Peak read traffic in the cluster × 3.

  Peak write traffic in the cluster × 3.

• For information about the billing rules of traffic specifications of subscription instances, see Billing of Internet traffic.

• For information about the billing rules of traffic specifications of pay-as-you-go instances, see Billing of Internet traffic.

• Average traffic × Storage duration × 3 (replicas).

• Messages can be retained for up to 7 days.

Specify the number of partitions based on your business requirements. We recommend that you change the number of partitions to reduce costs when you migrate data from a self-managed Apache Kafka cluster to the cloud.

Professional Edition (High Write)

• Average traffic × Storage duration × 3 (replicas).

• Select a storage engine based on your business requirements. For information about the differences between cloud storage and local storage, see Comparison between storage engines.

• You can specify a custom message storage duration based on your business scenario.

Professional Edition (High Read)

Serverless instances

Standard Edition

• Reserved capacity for message publishing: (Peak business traffic for message publishing in the cluster × 3)/2.

  Reserved capacity for message subscription: (Peak business traffic for message subscription in the cluster × 3)/2.

• The capacity that you can reserve for message publishing ranges from 60 MB/s to 51,300 MB/s, and the capacity that you can reserve for message subscription ranges from 20 MB/s to 17,100 MB/s.

You do not need to specify a disk size because cloud storage is used for topics on serverless instances. Messages can be stored for 1 day to 365 days. If you require a longer message storage duration, submit a ticket.
