Create a Flagship Edition cluster instance

Before using Flagship Edition, you must create a Flagship Edition cluster instance. This topic describes how to create an instance.

Prerequisites

You have registered an OceanBase Cloud account.

Procedure

Create a cluster from the OceanBase official website

1. Log in to the OceanBase Cloud console.

2. On the Instances page, click Create Instance in the upper-right corner to go to the instance creation page.

3. Select Flagship Edition as the instance type.

   Flagship Edition supports tenants for different workload types in the same cluster, including tenants in MySQL, Oracle, HBase API, and Table API compatibility modes.

4. In the billing and service section, select a billing method. You can select subscription or pay-as-you-go.

5. Select a cloud vendor and region. To reduce network latency and improve access speed, select a region close to your business.

6. Configure the instance.

   Parameter	Description
   Instance Name	Set the instance name. It must be 2 to 64 characters in length and can contain only Chinese characters, digits, English letters, underscores, and hyphens.
   Storage Architecture	Shared Nothing: Computing resources and data are stored on the same node. Data is processed locally on compute nodes, reducing data transfer overhead and improving computing efficiency. This architecture is simple and easy to maintain. Shared Storage: This cloud-native architecture separates storage from computing. Multiple compute nodes in a cluster use shared storage, allowing compute and storage resources to scale independently for greater cost efficiency and flexibility.
   Version	Select an OceanBase Database version. We recommend selecting the latest stable version. The drop-down list displays the major features of each version for reference.
   Deployment Mode	Dual-IDC Deployment: Two full-featured nodes are deployed in two zones, together with an arbitration node. The arbitration node does not synchronize or replay logs, store Redo logs or baseline data, or provide read/write services. Single-IDC Deployment (Two Nodes): Two full-featured nodes are deployed in the same zone, eliminating the latency caused by cross-zone or cross-IDC communication. Multi-IDC Deployment: Three nodes are deployed in three different zones to provide cross-zone disaster recovery. Single-IDC Deployment (Three Replicas): Three full-featured nodes are deployed in the same zone, eliminating the latency caused by cross-zone or cross-IDC communication.
   Zone	Select the target zone. You can click View Network Latency to select a zone with lower network latency. Single-IDC deployment: Select one zone. Both two-node and three-replica deployment modes are supported. Dual-IDC deployment: Select two zones. Multi-IDC deployment: Select three zones.
   Compute	Flagship Edition supports multiple compute specifications, such as 4C+32GiB, 8C+32GiB, 16C+64GiB, and 32C+128GiB. The specifications are named based on host resource configurations. The memory value in a specification indicates the total host memory, including memory occupied by the system and memory available to users.
   Storage	Available storage specifications vary based on the node specification. Select an appropriate storage capacity based on your business requirements.

7. Select the subscription duration and quantity.

8. In the Summary section on the right, verify that the configurations are correct and that the instance type is Flagship Edition. Then, click Create Instance and complete the payment.

What to do next

After the cluster is created, you can create tenants for different workload types in the cluster. For more information, see Create a tenant.
