Delegate Subdomains

How to delegate subdomains to another Cloud Provider

When managing a domain, such as example.com, you may want to delegate control of specific subdomains to different cloud platforms. The guide will help you go through the steps how to delegate subdomain from a Cloud Provider to a hosted zone in AWS and GCP.

Lets assume you have example.com registed in a DNS Provider such as GoDaddy or CloudFlare, and we want to be able to delegate:

• aws.example.com. to your AWS account

• gcp.example.com. to your GCP account

Delegate subdomains to AWS

For DNS management, AWS offers Amazon Route 53. Here are the steps you need to take:

1. Create a public hosted zone for aws.example.com in Route 53.

2. Note down the nameserver (NS) records that Route 53 assigns to your new hosted zone

3. To delegate the DNS control, you need to update the DNS settings of your primary domain example.com in the DNS Provider.

4. Go to where example.com is hosted, and add NS records for aws.example.com, pointing to the nameservers you noted from AWS Route 53.

This configuration delegates the management of aws.example.com to AWS.

Delegate subdomains to GCP

1. Create a managed zone for gcp.example.com in Google Cloud DNS.

2. Note down the nameserver (NS) records assigned to the managed zone.

3. Update the DNS settings for your primary domain example.com in your DNS Provider to delegate GCP:

4. Go to where example.com is hosted. and add NS records for gcp.example.com, pointing to the nameservers noted from Google Cloud DNS.

This configures the delegation of gcp.example.com to GCP.
