A company is migrating a critical enterprise application to Google Cloud. The application requires a dedicated, private, and high-bandwidth connection between its on-premises data center and the Google Cloud VPC network. The connection must not traverse the public internet. Which Google Cloud networking product should the company use?
- ACloud VPN
- BVPC Network Peering
- CShared VPC
- DCloud Interconnect (Dedicated)
Show answer & explanationAnswer & explanation
Correct answer: D. Cloud Interconnect (Dedicated)
Cloud Interconnect (Dedicated) provides a direct physical connection between an on-premises data center and Google's network, offering high bandwidth (10 Gbps or 100 Gbps), low latency, and a private connection that bypasses the public internet. This meets all critical enterprise application requirements.
Why the other options are wrong
- A. Cloud VPN uses encrypted tunnels over the public internet, which doesn't meet the 'not traverse the public internet' requirement.
- B. VPC Network Peering connects two VPC networks within Google Cloud, not an on-premises data center.
- C. Shared VPC allows multiple projects to share a common VPC network, but doesn't provide on-premises connectivity.
Cloud Interconnect (Dedicated)
Provides a direct physical connection between your on-premises network and Google's network, offering high bandwidth and low latency.
- Dedicated circuit provisioned directly to Google's edge network.
- Bypasses the public internet for enhanced security and performance.
- Available in 10 Gbps or 100 Gbps connections.
- Requires colocation at a Google-supported facility.
Memory trick: Interconnect is the 'direct highway' from your building to Google's cloud, no side roads (internet).
