Managing Instances
Overview
Data migration provides independent clusters for secure and reliable data migration. Clusters are isolated from each other and cannot access each other. You can create and manage clusters.
Purchasing a GDS-Kafka Instance
To use the data migration feature, you need to purchase a GDS-kafka instance (cluster). Cluster instances provide secure and reliable data migration services. Clusters are isolated from each other.
- Currently, only standalone clusters are supported.
- Only the pay-per-use billing mode is supported.
Procedure
- Log in to the GaussDB(DWS) console.
- In the navigation pane on the left, choose Data Migration > Instances.
- In the upper right corner of the page, click Buy GDS-Kafka Instance. Configure cluster parameters.
Table 1 Parameter description Parameter
Description
Example Value
CPU Architecture
The following CPU architectures can be selected:
- x86
- Kunpeng
NOTE:The only difference between the x86 and Kunpeng architectures lies in the underlying architecture, of which the application layer is unaware. The same SQL syntax is used. If x86 servers are sold out when you create a cluster, select the Kunpeng architecture.
x86
Flavor
Select a node flavor.
-
Capacity
Storage capacity of a node.
-
Current Flavor
Current flavor of the cluster.
-
Name
Set the name of the data warehouse cluster.
Enter 4 to 64 characters. Only case-insensitive letters, digits, hyphens (-), and underscores (_) are allowed. The value must start with a letter. Letters are not case-sensitive.
-
Version
Version of the database instance installed in the cluster. The version in the screenshot is for reference only.
8.2.1.300
VPC
Specify a VPC to isolate the cluster's network.
If you create a data warehouse cluster for the first time and have not configured the VPC, click View VPC. On the VPC management console that is displayed, create a VPC as needed.
-
Subnet
Specify a VPC subnet.
A subnet provides dedicated network resources that are isolated from other networks, improving network security.
-
Security Group
Specify a VPC security group.
A security group restricts access rules to enhance security when GaussDB(DWS) and other services access each other.
-
EIP
Specify whether users can use a client to connect to a cluster's database over the Internet. The following methods are supported:
- Do not use: Do not specify any EIPs here. If GaussDB(DWS) is used in the production environment, first bind it to ELB, and then bind it to an EIP on the ELB page.
- Automatically assign: Specify bandwidth for EIPs, and the system will automatically assign EIPs with dedicated bandwidth to clusters. You can use the EIPs to access the clusters over the Internet. The bandwidth name of an automatically assigned EIP starts with the cluster name.
- Specify: Specify an EIP to be bound to the cluster. If no available EIPs are displayed in the drop-down list, click Create EIP to go to the Elastic IP page and create an EIP as needed. The bandwidth can be customized.
-
Enterprise Project
Select the enterprise project of the cluster. You can configure this parameter only when the Enterprise Project Management service is enabled. The default value is default.

- Confirm the information and click Submit.
Viewing Instance Details
On the instance details page, you can view the basic information and network information about the cluster.
Procedure
- Log in to the GaussDB(DWS) console.
- In the navigation pane on the left, choose Data Migration > Instances.
- Click the name of an instance to go to the instance details page.
