Google Cloud Digital LeaderDigital transformation with Google CloudMedium
A large enterprise is looking to migrate its on-premises data centers to Google Cloud. A key concern is ensuring secure and high-speed network connectivity between their existing data centers and the Google Cloud environment. They need a dedicated, private connection that bypasses the public internet. Which Google Cloud networking solution should they choose?
- ACloud VPN for encrypted connections over the public internet.
- BCloud Interconnect (Dedicated or Partner) for private connections.
- CDirect Peering for direct network connections with Google.
- DVPC Network Peering for connecting two Google Cloud VPC networks.
Show answer & explanationAnswer & explanation
Correct answer: B. Cloud Interconnect (Dedicated or Partner) for private connections.
Cloud Interconnect (Dedicated or Partner) provides a direct, private connection between an on-premises network and Google Cloud, bypassing the public internet, which directly addresses the requirement for secure, high-speed, and private connectivity.
Why the other options are wrong
- A. Cloud VPN uses the public internet, which the scenario explicitly wants to avoid.
- C. Direct Peering is for exchanging traffic directly with Google's network (e.g., for Google services like YouTube), not specifically for connecting an enterprise's on-premises network to their Google Cloud VPC.
- D. VPC Network Peering connects two VPC networks *within* Google Cloud, not an on-premises network to Google Cloud.
Cloud Interconnect
A networking service that provides a dedicated, high-bandwidth connection between an on-premises network and Google Cloud, bypassing the public internet.
- Available in two forms: Dedicated Interconnect (direct fiber connection) and Partner Interconnect (connection through a service provider).
- Offers improved security, reliability, and lower latency compared to VPN over the public internet.
- Essential for hybrid cloud architectures and large data migrations.
Memory trick: Interconnect is the direct private road, VPN is the public tunnel.
