Step 2: Create a Kafka Instance

Prerequisites

• To achieve fine-grained management of your cloud resources, create IAM user groups and users and grant specified permissions to the users. For details, see Creating a User and Granting DMS for Kafka Permissions.
• You have configured instance dependencies.

Procedure

1. Log in to the Kafka console, then click Create Instance in the upper right corner of the page.
2. Select a region closest to your application to reduce latency and accelerate access.
3. Select a project from the Project drop-down list.
4. Select one AZ or at least three AZs.
5. Specify the instance name and the enterprise project.
6. Set the instance information. For details, see Table 1.

   Table 1 Setting instance information

   Parameter	Description
   Version	Select 2.7. Fixed once the instance is created. Use the same version as your client.
   CPU Architecture	Select x86.
   Broker Flavor	Select kafka.2u4g.cluster.
   Brokers	Enter 3
   Storage space per broker	Select Ultra-high I/O and enter 100 GB. Total storage space = Storage space per broker × Broker quantity. After the instance is created, you cannot change the disk type.
   Disk Encryption	Do not enable disk encryption.
   Capacity Threshold Policy	Select Automatically delete.

7. Configure the instance network. For details, see Table 2.

   Table 2 Configuring instance network

   Parameter	Description
   VPC	Select the created VPC and subnet. You cannot change the VPC and subnet after the instance is created.
   Security Group	Select the created security group.

8. Configure the username and password for logging in to Kafka Manager. The Kafka Manager username cannot be changed once an instance is created.

   Kafka Manager is an open-source tool for managing Kafka clusters. After a Kafka instance is created, you can go to the instance details page to obtain the address for logging in to Kafka Manager. In Kafka Manager, you can view the monitoring statistics and broker information of your Kafka clusters.

9. Click Advanced Settings. For more information, see Table 3.

   Table 3 Advanced settings

   Parameter	Description
   Public Access	Do not enable it.
   Kafka SASL_SSL	Enable SASL_SSL. This setting is fixed once the instance is created.
   SASL/PLAIN	Enable SASL/PLAIN. Enable SASL/PLAIN to support both SCRAM-SHA-512 (enabled by default) and PLAIN.
   Username	The username will be used for accessing the instance.
   Password	The password will be used for accessing the instance.
   Automatic Topic Creation	Do not enable it.
   Tags	Skip it.
   Description	Skip it.

10. Click Create Now.
11. Confirm the instance information.
12. Return to the Kafka Premium page and check whether the instance has been created.

    It takes 3 to 15 minutes to create an instance. During this period, the instance status is Creating.

    • If the instance is created successfully, its status changes to Running.
    • If an instance fails to be created, view it in the Instance Creation Failures area and delete it. Then create a new one. If the instance creation fails again, contact customer service.
      

      Instances that fail to be created do not occupy other resources.
