Question

Your company runs an enterprise platform on-premises using virtual machines (VMs). Your internet customers have created tens of thousands of DNS domains pointing to your public IP addresses allocated to the VMs. Typically, your customers hard-code your IP addresses in their DNS records. You are now planning to migrate the platform to Compute Engine and you want to use Bring Your Own IP. You want to minimize disruption to the platform. What should you do?

Options

  • ACreate a VPC and request static external IP addresses from Google Cloud. Assign the IP
  • BVerify ownership of your IP addresses. After the verification, Google Cloud advertises and
  • CCreate a VPC with the same IP address range as your on-premises network. Assign the IP
  • DVerify ownership of your IP addresses. Use live migration to import the prefix. Assign the IP

Explanation

To minimize disruption and ensure continuity of service when migrating to Google Cloud using Bring Your Own IP (BYOIP): Verify Ownership: Google Cloud requires you to verify that you own the public IP addresses before they can advertise them on behalf of your organization. This process involves proving that you control the IP prefix through mechanisms like WHOIS registration. Google Advertises the IP Prefix: Once ownership is verified, Google Cloud advertises your IP range globally, ensuring your existing customers' DNS records pointing to these IPs remain Assign IPs to Compute Engine Instances: After the prefix is provisioned, you can assign the IPs to the Compute Engine instances, maintaining continuity without requiring your customers to update their DNS records.
