Multi-cloud VPN Setup Between GCP and AWS
Organizations increasingly adopt multi-cloud VPN strategies to deliver reliable IT solutions, avoid vendor lock-in, and leverage cloud cost optimization. A secure VPN enables private connectivity across multiple cloud environments, ensuring seamless communication between resources in GCP and AWS.
Why Use a Multi-cloud VPN?
A multi-cloud VPN provides encrypted tunnels using IPSec protocols, allowing private IP-based access across clouds. This setup safeguards data in transit while enabling dynamic routing. By implementing BGP (Border Gateway Protocol), route updates from customer gateways propagate automatically when a VPN connection becomes active. Consequently, businesses can maintain highly available and resilient cloud networks.
Moreover, adopting multi-cloud strategies can benefit from consulting and managed services. ZippyOPS offers expertise in DevOps, DevSecOps, DataOps, Cloud, Automated Ops, AIOps, and MLOps to simplify complex deployments while ensuring security and efficiency. Learn more about ZippyOPS services.
Step 1: Reserve a Static IP in GCP
- Navigate to VPC Network > External IP Addresses.
- Click Reserve Static Address and confirm the reservation.
- Verify the assigned IP on the External IP Addresses page.
This IP will serve as the Customer Gateway IP in AWS.
Step 2: Configure VPC on AWS
- Open the VPC Dashboard and launch the VPC Wizard.
- Select VPC with a Private Subnet Only & Hardware VPN Access.
- Create a subnet to be shared with GCP, allowing secure communication over the VPN.
- Use the GCP reserved IP as the Customer Gateway.
- Complete the wizard to create the VPC and associated VPN.
Step 3: Download VPN Configuration from AWS
- Select the VPN and click Download Configuration.
- Choose Vendor: Generic, Platform: Generic, Software: Vendor Agnostic.
- Download the file containing Virtual Gateway IPs and IKE pre-shared keys.
AWS provides two tunnels by default for redundancy. These details will be used to configure GCP’s VPN.
Step 4: Create Cloud VPN in GCP
- Go to Hybrid Connectivity > VPN and select Create a VPN.
- Choose Classic VPN, then create a VPN Gateway using the reserved External IP.
- Enter tunnel details from the AWS configuration file.
- Create a Cloud Router with the Google ASN provided.
- Establish a BGP session, entering the Peer ASN and BGP IPs from AWS.
- Repeat the process for Tunnel 2 using the second section of the AWS configuration file.
Using this method, the VPN tunnels and BGP sessions enable secure, automated routing between GCP and AWS subnets.
Step 5: Validate VPN Connectivity
GCP: Navigate to Cloud VPN Tunnels and confirm the tunnel and BGP session status show as Established.
AWS: Check the Tunnel Details tab in the VPN dashboard to ensure both tunnels display UP status.
Once active, this multi-cloud VPN enables seamless and private communication between cloud environments.
