Serverless databases: Connect via a private endpoint

To better protect your database connection, you can connect to a private endpoint using the DataStax Astra DB private endpoint.

Private endpoints available on only serverless databases.

Get private endpoints information with the DevOps API

Use the DevOps API to create, remove, and manage private endpoints.

You can use the DevOps API to perform the actions your role permissions allow.

The following roles can manage private endpoints:

Organization Administrator
Database Administrator

Alternatively, you can use a custom role with permissions to manage private endpoints.

Prerequisites

Ensure you have permission to manage private endpoints.

To increase your security, consider restricting public access to your database using the access list.

Getting a list of private endpoint configurations

Check existing private endpoint configurations within your organization or database:

cURL command (/v2): Get all private endpoints in organization
cURL command (/v2): Get all private endpoints in database
Result

curl --request GET \
  --url 'https://api.astra.datastax.com/v2/organizations/<organizationID>/clusters/private-link' \
  --header 'Accept: application/json' \
  --header 'Authorization: Bearer <application_token>'

curl --request GET \
  --url 'https://api.astra.datastax.com/v2/organizations/clusters/<databaseId>/private-link' \
  --header 'Accept: application/json' \
  --header 'Authorization: Bearer <application_token>'

{
  "provider": "aws",
  "region": "us-east-1",
  "description": "Private Endpoint B",
  "organizationId": "string",
  "datacenterID": "string",
  "endpoints": [
    {
      "id": "string",
      "dateActivation": "1997-12-09T02:03:33.57Z",
      "dateDeactivation": "1997-12-09T02:03:33.57Z"
    }
  ]
}

Getting a list of private endpoint connections

Check existing private endpoint connections within your organization or database:

cURL command (/v2): Get all private endpoint connections in organization
cURL command (/v2): Get all private endpoint connections in database
cURL command (/v2): Get all private endpoint connections in specified region
Result

curl --request GET \
  --url 'https://api.astra.datastax.com/v2/organizations/clusters/private-link' \
  --header 'Accept: application/json' \
  --header 'Authorization: Bearer <application_token>'

curl --request GET \
  --url 'https://api.astra.datastax.com/v2/organizations/clusters/<databaseID>/private-link' \
  --header 'Accept: application/json' \
  --header 'Authorization: Bearer <application_token>'

curl --request GET \
  --url 'https://api.astra.datastax.com/v2/organizations/clusters/<databaseID>/datacenters/<datacenterID>/private-link' \
  --header 'Accept: application/json' \
  --header 'Authorization: Bearer <application_token>'

If the database is only in a single region, datacenterID is your databaseID.

{
  "clusters": [
    {
      "databaseID": "string",
      "datacenters": [
        {
        "serviceName": "com.amazonaws.vpce.us-east-1.vpce-svc-1148ea04af491da11",
        "allowedPrincipals": [
          "arn:aws:iam::123456789012:role/admin"
        ],
        "datacenterID": "string",
        "endpoints": [
          {
            "endpointID": "vpce-svc-1148ea04af491da11",
            "description": "ecomm-team-billing-app",

Explore Private endpoints in the DevOps API.

To better protect your database connection, you can connect to a private endpoint using the Astra DB private endpoint. Private endpoints are available for only intra-region use. The region for your private endpoint in the AWS console and your Astra DB database must match.

For pricing related to using private endpoints, see Pricing and billing.

The following roles can manage private endpoints:

Organization Administrator
Database Administrator

Alternatively, you can use a custom role with permissions to manage private endpoints.

For more about AWS PrivateLink, see AWS PrivateLink.

Prerequisites

Create your Astra DB database using Astra Portal.
Ensure you have permission to manage private endpoints.
Get your application token.

Only VPC owners can create resources such as VPC endpoints, subnets, route tables, and NACLs. Participants cannot view, modify, or delete resources that belong to other participants or the VPC owner. Thus a user cannot create resources, including a private endpoint, in a shared VPC that is owned by a different AWS account. To see which account owns your VPC, look at the Owner ID in the AWS Console. Example:

For more, see Work with shared VPCs - Amazon Virtual Private Cloud.

To increase your security, restrict public access to your database using the access list.

If you are using Postman for your API calls, ensure you use the raw option to enter the body of your API call.

Connect to your AWS PrivateLink endpoint

Get the allowed principal from your AWS account.
1. In your AWS console on the Identify and Access Management (IAM) Users page, select your user name from the available users.
2. Select the User ARN as your allowed principal. For example, arn:aws:iam::123456789012:root.

Enter the allowed principal for your private endpoints to Astra DB:

cURL command (/v2)
Result

curl --request POST \
  --url 'https://api.astra.datastax.com/v2/organizations/clusters/<databaseID>/datacenters/<datacenterID>/private-link' \
  --header 'Accept: application/json' \
  --header 'Authorization: Bearer <application_token>' \
  --data '{
      "allowedPrincipals": [
        "arn:aws:iam::123456789012:role/admin"
      ]
    }'

To confirm your datacenter ID, see your database Dashboard or use the DevOps API to get all datacenter IDs within your database.

{
  "serviceName": "com.amazonaws.vpce.us-east-1.vpce-svc-1148ea04af491da11",
  "allowedPrincipals": [
    "arn:aws:iam::123456789012:role/admin"
  ]
}

Use the serviceName to create an endpoint in your AWS Console.
