This topic describes how to purchase an OpenSearch Retrieval Engine Edition instance.

Prerequisites

  1. You have registered an Alibaba Cloud account and completed real-name verification.

  2. When you activate an Alibaba Cloud account and log on to the console, you are prompted to create an AccessKey before you can continue.

  3. Creating and using applications depends on AccessKey parameters. The AccessKey parameters of the Alibaba Cloud account cannot be empty.

  4. After you create AccessKey parameters for the Alibaba Cloud account, you can also create an AccessKey for a RAM user and access resources as the RAM user. To grant the required access permissions to the RAM user, see Create and authorize a RAM user. (Note: The RAM user must be granted the AliyunSearchEngineFullAccess and AliyunSearchEngineReadOnlyAccess permissions to access Retrieval Engine Edition instances.)

  5. You must have a VPC environment.

Note

  • If you want to use a RAM user to manage Retrieval Engine Edition instances, use the Alibaba Cloud account to grant the AliyunSearchEngineFullAccess and AliyunSearchEngineReadOnlyAccess permissions to the RAM user.

Purchase an instance

  1. Go to the OpenSearch console and switch to OpenSearch Retrieval Engine Edition in the upper-left corner.

  1. In the Retrieval Engine Edition console, click Create Instance on the instance management page.

  1. Set the product edition to Retrieval Engine Edition, and select the Engine Type, Product Type, and Region. Configure "Number of Data Nodes", "Data Node Instance Family", "Data Node Specifications", "Total Storage per Data Node", "Number of Query Nodes", "Query Node Instance Family", and "Query Node Specifications". Set "VPC" and "vSwitch". Finally, set a username and password as prompted (used to verify permissions during queries; these are not your Alibaba Cloud account credentials), and click "Buy Now".

Note

  • Plan the number and specifications of query nodes and data nodes based on your business needs. After you determine the specifications, the actual fee is automatically generated on the buy page.

  • The VPC and vSwitch configurations must be the same as those of the ECS instance that accesses the Retrieval Engine Edition instance. Otherwise, the following error is reported when you access the Retrieval Engine Edition instance: {'errors':{'code':'403','message':'Forbidden'}}

  • Storage per data node:

    • Data nodes whose instance family is cloud disk-based or GPU-based do not provide free storage space.

    • Each specification of SSD-based data nodes provides a certain amount of free storage space. You can also apply for additional quota, and you are charged for the additional quota (in increments of 50 GB).

  1. On the Confirm Order page, read the service agreement, confirm that the information is correct, and then click Activate Now.

  1. After the purchase succeeds, click Console to view the purchased Retrieval Engine Edition instance on the instance management page:

    The page indicates that the service is being activated. This usually takes 1 to 5 minutes. Please wait.

  1. A newly purchased instance is assigned a default instance name. To change it, click Manage in the Actions column to go to the details page:

    Click to modify the instance name, change the instance name as required in the dialog box, and then click OK:

    In the Basic Information section of the Instance Information page, find the Instance Name field and click the edit (pencil) icon to its right.
