Click Create Instance on the page.
On the Create Instance page, select Dedicated (Transactional) as Instance Type.
Select a deployment region.
Configure the instance specification.
ParameterDescriptionVersion The version of OceanBase Database. Deployment Mode - Single-IDC Deployment: All nodes are located in the same availability zone. Two or three replicas are supported in a single IDC. If this configuration is required, contact OceanBase Technical Support.
- Dual-IDC Deployment: Two nodes are deployed in two availability zones, and the third node is deployed in another availability zone, used only for log synchronization and not providing read/write services. Dual-IDC deployment provides the same high availability as multi-IDC deployment while significantly improving cost-effectiveness. This deployment mode applies to versions 4.1.0.0 and later.
- Multi-IDC Deployment: Primary and standby nodes are deployed in different availability zones, enabling cross-availability-zone disaster recovery. This deployment incurs no additional cost; all three availability zones are selected by default.
Zone - Single-IDC Deployment: Select 1 availability zone.
- Dual-IDC Deployment: Select 2 availability zones.
- Multi-IDC Deployment: Select 3 availability zones.
Compute/Storage Different compute specifications support different storage capacities. Choose based on your business needs. Choose whether to enable data encryption.
If you choose to enable data encryption, you can select one of the following key methods:
- Default Key: Use the default encryption method.
- Custom Key: Provide the ARN of the KMS key. For more information, see Manage KMS keys.
Notice
After data encryption is enabled, you cannot disable this feature.
In the Quantity section, select the number of instances you want to create.
