AnalyticDB:Create an instance

Prerequisites

• An Alibaba Cloud account is created. If you have not created an Alibaba Cloud account, visit the Alibaba Cloud official website to create an account.

• The AliyunGPDBFullAccess policy of AnalyticDB for PostgreSQL is attached to the Alibaba Cloud account or a Resource Access Management (RAM) user.

Free trial

Alibaba Cloud provides a free trial for new users of AnalyticDB for PostgreSQL V6.0 instances in elastic storage mode. If you are new to AnalyticDB for PostgreSQL, you can apply for a free trial. If you are ineligible for a free trial, you can perform the following procedure to create an instance in the AnalyticDB for PostgreSQL console.

Procedure

1. Log on to the AnalyticDB for PostgreSQL console.

2. The first time you create an AnalyticDB for PostgreSQL instance, you must create a service-linked role. In the Create Service Linked Role message, click OK.

3. In the upper-right corner of the console, click Create Instance.

4. Configure the Product Type parameter. Valid values:

   • Subscription: You must pay an upfront subscription fee when you create an instance. For long-term use, the subscription billing method is more cost-effective than the pay-as-you-go billing method. You are charged lower prices for longer subscription durations.

   • Pay-as-you-go: A pay-as-you-go instance is billed per hour based on your actual resource usage. For short-term use, we recommend that you select the pay-as-you-go billing method. If you no longer need a pay-as-you-go instance, you can release the instance to reduce costs.

5. On the buy page, configure the parameters that are described in the following table.

   Parameter	Description
   Region and Zone	The region where you want to create the instance. Note After you complete the purchase, you cannot change the region of the instance. To accelerate access to the instance, we recommend that you select a region that is close to your geographical location. Make sure that the AnalyticDB for PostgreSQL instance is deployed in the same region as the Elastic Compute Service (ECS) instance to which you want to connect. Otherwise, you cannot connect these instances over an internal network and make them deliver the optimal performance.
   	The zone where you want to create the instance. Each zone is an independent physical location within a region. Zones in the same region do not have substantial differences. You can create the instance in the same zone as the ECS instance to which you want to connect or in a different zone.
   Instance Resource Type	The resource type of the instance. Select Elastic Storage Mode. Note The resource types that are available vary based on the region and zone. If the current region and zone do not provide the required instance resource type, change the region and zone. For information about the resource types that are available in different regions and zones, see Instance specifications.
   Edition	The edition of the instance. Valid values: High-performance Edition (Basic Edition) and High-availability Edition. Note You can select High-performance Edition (Basic Edition) only when you set the Instance Resource Type parameter to Elastic Storage Mode. For more information, see High-performance Edition.
   Engine Version	The engine version of the instance. Select 6.0 Standard Edition.
   Vector Engine Optimization	Specifies whether to enable vector search engine optimization. Select Enabled. Vector search engine optimization can improve the performance of your instance in vector analysis, but consumes large amounts of memory resources and significantly reduces query concurrency. Before you enable vector search engine optimization, make sure that you understand its impact. Note You can enable vector search engine optimization only for V6.0 instances in elastic storage mode. You can enable vector search engine optimization only for instances whose compute node specifications are 4 cores and 32 GB or higher.
   Coordinator Node Resources	The specifications of coordinator node resources. We recommend that you select coordinator node resources with the number of compute units (CUs) to be equal to the number of CPU cores per compute node. If you need more coordinator node resources, you can add more resources after you create the instance. For more information, see Manage coordinator node resources. Note This parameter is unavailable for instances in Serverless auto scheduling mode.
   Compute Node Specifications	The specifications of compute nodes. The available specifications vary based on the resource type and edition. For more information, see Instance specifications. Note This parameter is unavailable for instances in Serverless auto scheduling mode.
   Compute Nodes	The number of compute nodes. The instance performance increases with the number of compute nodes. The number of compute nodes that you can select varies based on the resource type and edition. Valid values for High-performance Edition instances in elastic storage mode: 2 to 512, in 2 increments. Valid values for High-availability Edition instances in elastic storage mode: 4 to 512, in 4 increments.
   Disk Storage Type	The disk storage type. Valid values: PL1 ESSD (Recommended) ESSD_PL0 PL2 ESSD (High-throughput) For information about the performance differences between the disk storage types, see Block storage performance. Note This parameter is available only for instances in elastic storage mode.
   Encryption Type	The encryption type of the instance. You can select Not Encrypted or Disk Encryption. Note This parameter is available only for instances in elastic storage mode.
   CMK	The encryption key of disks. This parameter is available only when you select Elastic Storage Mode and Disk Encryption.
   Single Node Storage Capacity	The storage capacity of each node in the instance. Unit: GB. Valid values: 50 to . The value must be a multiple of 50. Note This parameter is available only for instances in elastic storage mode.
   Network Type	The network type of the instance. The value is automatically set to VPC.
   VPC	The ID of the virtual private cloud (VPC) in which the instance resides. A VPC is an isolated virtual network that provides higher security and higher performance than the classic network. Before you configure this parameter, make sure that a VPC and a vSwitch are created in the region where you want to create the instance.
   vSwitch	The vSwitch to which the instance is connected. If no optional vSwitches are available, you can switch to another zone or create a vSwitch in the current zone.
   Resource Group	The resource group to which the instance belongs. For more information about resource groups, see What is Resource Management?
   Sample Data	Specifies whether to load sample data to the instance. For information about the sample dataset, see Manage a sample dataset.
   Service-linked Role	The service-linked role. If you have already created a service-linked role, Created is displayed on the buy page. If you have not created a service-linked role, click Create Service-linked Role.
   Duration	The subscription duration of the instance. Note This parameter is available only when you set the Product Type parameter to Subscription.

6. Click Buy Now.

7. On the Confirm Order page, perform the following operations based on the value of the Product Type parameter:

   • Subscription

     1. Confirm the information in the Parameters section, read and select the Terms of Service, and then click Pay.

     2. On the Purchase page, click Subscribe.

   • Pay-as-you-go

     Confirm the information in the Parameters section, read and select the Terms of Service, and then click Activate Now.

8. After the instance is created, go to the Instances page to view the instance.

   Note

   It takes a period of time to initialize an AnalyticDB for PostgreSQL instance. You can perform operations only when the instance is in the Running state.
