Version: User Guides (BYOC)


This topic details the prerequisites required for activating the Zilliz Cloud Bring Your Own Cloud (BYOC) license. It's essential to ensure these initial steps are completed before proceeding to the detailed activation steps provided in Activate Your License. The prerequisites outlined here are foundational for a successful and efficient activation process.


The following diagram shows the architecture for BYOC deployment. The control plane is hosted within Zilliz Cloud. With necessary authorization, Zilliz Cloud establishes a secure connection via Private Link to access the customer's VPC. It then creates cloud resources and deploys the BYOC components under the customer's cloud account.


Verify subscription via welcome email

Upon subscribing to a BYOC license, you will receive a welcome email with your subscription details, including your license ID, core size, and validity period. Verify these details for accuracy before proceeding.


Set up your environment

  1. Operating System Compatibility: Ensure that your machine operates on one of the following systems:

    • Linux

    • macOS

    • Windows

  2. Terraform Installation: Zilliz Cloud utilizes Terraform for managing the cloud infrastructure required for BYOC deployment.

    • macOS

      brew tap hashicorp/tap
      brew install hashicorp/tap/terraform
    • CentOS/RHEL

      sudo yum install -y yum-utils
      sudo yum-config-manager --add-repo
      sudo yum -y install terraform

    If you use Windows or other Linux distributions, refer to Terraform official documentation for installation.

Prepare your accounts

Activation requires two accounts:

  1. AWS Account: Your Zilliz Cloud BYOC deployment will be hosted within your AWS account. If you do not have an AWS account, create one following the AWS Account Creation Guide. The Zilliz Cloud BYOC solution currently supports the AWS us-west-2 region. For other cloud providers or regions, contact our sales team.

  2. Zilliz Cloud Account: Use the account you provided to Zilliz Cloud technical support during the contract signing process.

Create temporary security credentials

To activate your BYOC license using Terraform scripts, you'll need to provide temporary security credentials. These include an access key and a secret key, for AWS cloud resources. It's advisable to create these credentials solely for the activation process and deactivate them afterward.

Here's how to create temporary security credentials:

  1. Sign in to the IAM console using your AWS account ID and password.

  2. Go to the Access keys section and click Create access key.

  3. On the Retrieve access keys page, choose either Show to reveal the value of your user's secret access key, or Download .csv file. This is your only opportunity to save your secret access key. After you've saved your secret access key in a secure location, choose Done.

For detailed instructions, refer to AWS official documentation.


Understand required resources and permissions

Deploying Zilliz Cloud BYOC requires specific cloud resources and permissions within your AWS account.

Resource quotas

Refer to the table below for the necessary cloud resources and services for Zilliz Cloud BYOC activation. If the cloud resources in your current account are insufficient, contact your cloud account administrator to increase quotas.


Cloud administrators can monitor resource usage and quotas in the cloud quota dashboard. For details, refer to AWS service quotas.
