To use OpenSearch Vector Search Edition, you must purchase an OpenSearch Vector Search Edition instance. This topic describes how to purchase an OpenSearch Vector Search Edition instance.
Prerequisites
An Alibaba Cloud account is created and passes real-name verification.
An AccessKey pair is created for the Alibaba Cloud account. When you create an Alibaba Cloud account and log on to the OpenSearch console by using the Alibaba Cloud account for the first time, you are prompted to create an AccessKey pair before you perform subsequent operations.
To create and use an OpenSearch application, your Alibaba Cloud account must have an AccessKey pair.
After you create an AccessKey pair for your Alibaba Cloud account, you can create an AccessKey pair for a Resource Access Management (RAM) user within the Alibaba Cloud account. This way, you can access applications as the RAM user. For more information about how to grant permissions to a RAM user, see RAM authorization. Note: The RAM user must be granted the AliyunSearchEngineFullAccess or AliyunSearchEngineReadOnlyAccess permission to access OpenSearch Vector Search Edition instances.
A virtual private cloud (VPC) is created. For more information about VPC, see What is a VPC?
If you want to access OpenSearch Vector Search Edition instances as a RAM user, you must grant the AliyunSearchEngineFullAccess or AliyunSearchEngineReadOnlyAccess permission to the RAM user by using your Alibaba Cloud account.
Procedure
Log on to the OpenSearch console. In the upper-left corner, switch to OpenSearch Vector Search Edition.
In the left-side navigation pane, click Instances. On the Instances page, click Create Instance.
On the buy page, select Vector Search Edition as the service edition and configure the following parameters for the OpenSearch Vector Search Edition instance: Region and Zone, QRS Workers, QRS Worker Specifications, Searcher Workers, Searcher Worker Specifications, Total Storage Space of Single Searcher Worker, VPC, and vSwitch. Then, specify a username and password and click Buy Now. The username and password are used for permission verification in queries. We recommend that you do not specify your Alibaba Cloud account and password as the username and password.
Specify the numbers and specifications of Query Result Searcher (QRS) workers and Searcher workers that you want to purchase based on your business requirements. After you specify the specifications, the actual fee is automatically displayed on the buy page.
If you purchase a single-worker instance, you do not need to modify the number of QRS workers. Use the default value 0.
You must specify the same VPC and vSwitch as those of the Elastic Compute Service (ECS) instance that you use to access the OpenSearch Vector Search Edition instance. Otherwise, the error {'errors':{'code':'403','message':'Forbidden'}} is returned when you access the OpenSearch Vector Search Edition instance.
A free quota of storage space is provided for each Searcher worker. You can purchase more storage in increments of 50 GB. If the total storage space exceeds the free quota, you are charged for the excess storage space.
On the Confirm Order page, check the configurations, agree to the service agreement, and then click Activate Now.
After you purchase the instance, click Console. On the Instances page, you can view the purchased instance.
By default, the name of the instance is automatically specified. To modify the name of the instance, click Manage in the Actions column to go to the instance details page.
In the Basic Information section of the Instance Details page, click the Edit icon next to the instance name. In the dialog box that appears, modify the instance name as prompted, and click Confirm.
