Google Cloud Digital LeaderDigital transformation with Google CloudMedium
A large enterprise is planning a significant digital transformation that involves migrating its existing on-premises data centers to Google Cloud. A key requirement is to establish a highly secure, private, and low-latency connection between their on-premises network and Google Cloud, bypassing the public internet, to ensure data integrity and meet stringent compliance regulations. Which Google Cloud service should they use?
- ACloud Interconnect
- BDirect Peering
- CCloud CDN
- DCloud VPN
Show answer & explanationAnswer & explanation
Correct answer: A. Cloud Interconnect
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. This makes it ideal for large-scale data center migrations with strict compliance and performance requirements.
Why the other options are wrong
- B. Direct Peering allows direct network connection to Google's edge network for public Google services, but is not designed for private, dedicated connectivity to a customer's VPC network.
- C. Cloud CDN (Content Delivery Network) is for caching and delivering web content closer to users, not for establishing private network connectivity between on-premises and cloud environments.
- D. Cloud VPN establishes an encrypted connection over the public internet, which may not meet the 'private' and 'bypassing the public internet' requirements for stringent compliance and performance.
Cloud Interconnect
A Google Cloud service that provides a dedicated, high-bandwidth, low-latency connection between your on-premises network and Google Cloud.
- Private connection, bypasses public internet
- Higher bandwidth and lower latency than VPN
- Dedicated Interconnect or Partner Interconnect options
Memory trick: Interconnect is like a 'private highway' between your home and the cloud.
