Configuration Description Version The OceanBase database version. Deployment Mode - Single-IDC Deployment: All nodes are located within the same zone. This deployment supports both two-node and three-node configurations within a single IDC. If you require this setup, please contact OceanBase technical support.
- Dual-IDC Deployment: Two nodes are deployed across two zones, with a third node deployed in a different zone solely for log synchronization. This node does not provide read/write services. Dual-IDC deployment offers the same availability as multi-IDC deployment but with significantly improved cost efficiency. The dual-IDC deployment option is supported in versions 4.1.0.0 and later.
- Multi-IDC Deployment: Primary and standby nodes are located in different zones, enabling disaster recovery across zones. This deployment comes at no additional cost and by default, all three zones are selected.
Zone - Single-IDC Deployment: choose 1 zone.
- Dual-IDC Deployment: choose 2 zones.
- Multi-IDC Deployment: choose 3 zones.
Compute/Storage Different compute specifications have different storage capacity, which you can select based on your business needs. Choose whether to enable data encryption.
If you choose to enable Data Encryption, you are provided with the following two options for your key:
- Default Key: Use the default encryption method.
- Custom Key: You need to provide the ARN of the KMS key. For more information, refer to KMS key management.
Note
It is not supported to disable data encryption once it is enabled.
Choose the number of instances you want to create under the Quantity section.
In the Summary section on the right, confirm the configurations and then proceed to payment to complete the purchase.
After the purchase is completed, you can navigate back to the Instances page to view the creation progress.
