This document describes how to use the Specification Calculator in the CKafka console to find the appropriate CKafka instance specification for your self-built Kafka cluster that needs to be migrated to the cloud.
Log in to the CKafka console.
On the left sidebar, select Migration to Cloud, select the region you want to migrate to, and click Specification Calculator.
Enter the specification of your self-built Kafka cluster on the specification calculator page.
|Kafka Version||Select the version of your self-built Kafka cluster. For more information on CKafka version selection, please see Suggestions for CKafka Version Selection.|
|Peak Business Bandwidth||Peak business bandwidth = max (production peak bandwidth * number of replicas, consumption peak bandwidth).|
|Disk||Estimate according to the current peak value of actual disk usage.|
