QuestionQ107

Designing and planning a cloud solution architecture

Your company has recently acquired another company with infrastructure in Google Cloud. Each company has its own Google Cloud organization. Both companies use a Shared Virtual Private Cloud (VPC) to provide network connectivity for their applications. Some subnets used by the two companies overlap. To integrate both businesses, the applications need private network connectivity. These applications are not on overlapping subnets. You want to provide connectivity with minimal re-engineering. What should you do?

  • A Set up VPC peering and peer each Shared VPC together.
  • B Migrate the projects from the acquired company into your company's Google Cloud organization. Re-launch the instances in your companies Shared VPC.
  • C Set up a Cloud VPN gateway in each Shared VPC and peer Cloud VPNs.
  • D Configure SSH port forwarding on each application to provide connectivity between applications in the different Shared VPCs.
Explanation

VPC Network Peering rejects peering configurations when subnet IP ranges overlap. Cloud VPN provides an IPsec connection between VPC networks and can be configured to carry traffic only for the non-overlapping application subnet ranges that require connectivity, avoiding an address-renumbering or instance-redeployment effort.
