Google Cloud Digital LeaderDigital transformation with Google CloudMedium
A large enterprise with a global presence is planning to migrate its on-premises data centers to Google Cloud. They require dedicated, high-bandwidth, and low-latency connectivity between their existing on-premises infrastructure and Google Cloud, bypassing the public internet for enhanced security and predictable performance. Which Google Cloud solution should they utilize?
- ACloud CDN
- BCloud VPN
- CCloud DNS
- DCloud Interconnect
Show answer & explanationAnswer & explanation
Correct answer: D. Cloud Interconnect
Cloud Interconnect provides direct physical connections between an on-premises network and Google's network, offering high bandwidth, low latency, and enhanced security by avoiding the public internet. This is ideal for large-scale migrations and hybrid cloud environments.
Why the other options are wrong
- A. Cloud CDN is for content delivery, not for private connectivity between on-premises and cloud networks.
- B. Cloud VPN uses encrypted tunnels over the public internet, which doesn't meet the 'bypassing public internet' requirement for predictable performance and security.
- C. Cloud DNS is a domain name system service, unrelated to private network connectivity.
