Create an instance

To use the services provided by OceanBase Cloud, you need to create an instance first. This topic introduces the procedure of creating an instance.

Procedure

Follow these steps to purchase an instance:

1. Log in to the OceanBase Cloud console.

2. On the Instances page, click Create Instance.

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

4. Select your cloud vendor and the deployment region. OceanBase Cloud now supports to select AWS as the cloud vendor.

5. 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. Shared Storage: This cloud-native architecture separates storage and computing in an instance by using multiple computing nodes and shared storage technology. The separated layers of computing and storage resources allow independent scaling and improve cost-effectiveness and flexibility. For more information, see Storage architecture.
   Version	The version of OceanBase Database. Currently, V4.2.1 and V4.3.5 are supported.
   Deployment Mode	Single-IDC Deployment: All nodes are located within the same zone. This deployment supports one-node, two-node, and three-node configurations within a single IDC. Note If you require this setup, please contact OceanBase technical support. Only when you purchase through AWS Marketplace and select V4.0.0 for Version, the one-node configuration is supported. 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	Supports five compute specifications: 4 cores 16 GiB, 8 cores 16 GiB, 16 cores 32 GiB, 32 cores 70 GiB, and 64 cores 180 GiB. Note The 4 cores 16 GiB and 64 cores 400 GiB specifications are currently only available to whitelisted users. If you need to purchase either of these two specifications, please contact OceanBase technical support.
   Storage	The storage specifications vary by compute specifications. Select the storage specification as needed. For more information, see Instance billing.

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

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

   The deployment is estimated to take 1 hour. You can check the creation progress on the Instances page.
