Google Cloud Digital LeaderDigital transformation with Google CloudMedium
A large enterprise is planning a significant digital transformation that involves migrating a substantial portion of its on-premises data centers to Google Cloud. A key requirement is to establish a highly reliable, low-latency, and secure network connection between their existing data centers and Google Cloud, bypassing the public internet. This connection is critical for hybrid cloud operations and large-scale data transfers. Which Google Cloud networking solution is best suited for this scenario?
- ACloud Interconnect
- BCloud CDN
- CCloud VPN
- DDirect Peering
Show answer & explanationAnswer & explanation
Correct answer: A. Cloud Interconnect
Cloud Interconnect (specifically Dedicated Interconnect or Partner Interconnect) provides a direct physical connection between an on-premises network and Google Cloud, bypassing the public internet. This ensures high bandwidth, low latency, and enhanced security crucial for large-scale migrations and hybrid cloud operations.
Why the other options are wrong
- B. Cloud CDN is a content delivery network for delivering web content to end-users, not for connecting on-premises data centers to Google Cloud.
- C. Cloud VPN uses encrypted tunnels over the public internet, which may not meet the requirements for 'bypassing the public internet' and 'high bandwidth, low latency' for large-scale transfers.
- D. Direct Peering allows exchanging traffic with Google's network, but it's primarily for exchanging public internet traffic and doesn't provide a private, dedicated connection for your VPC like Cloud Interconnect.
Cloud Interconnect
A networking service that provides a high-bandwidth, low-latency connection between your on-premises network and Google Cloud's network.
- Bypasses the public internet for enhanced security and performance.
- Available as Dedicated Interconnect (direct to Google) or Partner Interconnect (via a service provider).
- Essential for hybrid cloud architectures and large data migrations.
Memory trick: Interconnect makes on-prem and cloud connect.
