Create an instance

This topic provides the instructions on creating an instance through OceanBase Cloud official website.

Procedure

1. Log in to the OceanBase Cloud console.

2. In the left-side navigation pane, click Instances.

3. On the Instances page, click Create Instance.

4. On the Create Instance page, select the instance type as Dedicated (Key-Value).

5. Select a cloud vendor and deployment region. OceanBase Cloud supports the following cloud vendors: AWS, Alibaba Cloud, and Google Cloud.

6. Select your instance specifications.

   Parameter	Description
   Instance Name	Set the instance name. The name must be 2 to 64 characters in length and can contain only Chinese characters, digits, uppercase and lowercase letters, underscores, and hyphens.
   Storage Architecture	Shared Nothing: The computing resources and data storage are in the same node. Data is locally processed on the computing node. This reduces the overheads of data transmission and improves the computing efficiency. The architecture is simple and easy to maintain.
   Version	The version of OceanBase Database.
   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. For more information, see Deployment modes.
   Zone	Select the target zone. You can select the zone with the lowest network latency by using View Network Latency. Single-IDC Deployment: Select one zone. Dual-IDC Deployment: Select two zones. Multi-IDC deployment: Select three zones.
   Compute	Select the compute specification as needed.
   Storage Disk Type	Select the storage disk type as needed. When the storage architecture is Shared Nothing, only Alibaba Cloud instances support to select the storage disk type of ESSD PL0 or ESSD PL1.
   Storage	The storage specifications vary by compute specifications. Select the storage specification as needed. For more information, see Instance billing.

7. 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.

8. Specify the number of instances you want to create in the Quantity section.

9. In the Summary section on the right, review the configurations and then click Create Instance to complete the purchase.

   After the creation is completed, you can navigate back to the Instances page to view the creation progress.
