A manufacturing company is deploying a new application on Google Cloud that needs to connect to an on-premises database with minimal latency and high bandwidth. The database contains critical production data, and the connection must be highly reliable and secure. The company does not want to rely on the public internet for this connection. Which Google Cloud networking solution should you advise for connecting the Google Cloud application to the on-premises database?
- ACloud CDN for accelerating content delivery to on-premises users.
- BVPC Peering for connecting two Google Cloud VPC networks.
- CCloud VPN for encrypted tunnels over the public internet.
- DCloud Interconnect for a dedicated, private network connection.
Show answer & explanationAnswer & explanation
Correct answer: D. Cloud Interconnect for a dedicated, private network connection.
Cloud Interconnect provides a direct, private connection between an on-premises network and Google Cloud, offering higher bandwidth, lower latency, and enhanced security compared to VPN over the public internet, perfectly matching the requirements for critical production data.
Why the other options are wrong
- A. Cloud CDN is for content delivery, not for establishing private network connectivity between on-premises and cloud resources.
- B. VPC Peering connects two *Google Cloud* VPC networks, not an on-premises network to Google Cloud.
- C. Cloud VPN uses the public internet, which does not meet the 'do not want to rely on the public internet' requirement, and typically offers lower bandwidth than Interconnect.
Cloud Interconnect
Cloud Interconnect provides a direct, high-bandwidth, and low-latency network connection between an on-premises network and Google Cloud's network, bypassing the public internet.
- Comes in two types: Dedicated Interconnect and Partner Interconnect.
- Offers enhanced security and reliability compared to VPN over the internet.
- Ideal for hybrid cloud architectures with high data transfer needs.
Memory trick: To connect home to the cloud, use a private highway, not the public road.
