Creating a LakeFormation Instance and a Client Connection

Preparing a User

If you use LakeFormation for the first time, create a user and grant permissions to the user by referring to Preparations.

This section demonstrates the entire process of using LakeFormation. You need to complete the following preparations in advance:

• An IAM service user and user group for authorization have been created in IAM, and the user has been associated with the user group.
• A parallel file system has been created in OBS, and a folder for mapping data tables has been created in the file system.
• You have created an agency required for interconnecting with LakeFormation. For example, if you plan to interconnect MRS clusters with LakeFormation, create an agency by referring to Preparations.

1. Log in to the LakeFormation console.
2. In the upper left corner, click and choose Analytics > LakeFormation to access the LakeFormation console.
3. Click Buy Now or Buy Instance in the upper right corner.

   If a LakeFormation instance exists on the page, Buy Instance is displayed. Otherwise, Buy Now is displayed.

4. Configure the parameters listed in the following table.
