Google Associate Cloud EngineerPlanning and configuring a cloud solutionMedium
A company is migrating its on-premises applications to Google Cloud. They need to establish a secure and private connection between their on-premises data center and their Google Cloud VPC. The connection must offer high throughput and low latency, and the company is willing to deploy physical network infrastructure. Which Google Cloud networking product should they utilize?
- ACloud Load Balancing
- BCloud Interconnect
- CCloud VPN
- DCloud CDN
Show answer & explanationAnswer & explanation
Correct answer: B. Cloud Interconnect
Cloud Interconnect (specifically Dedicated Interconnect or Partner Interconnect) provides a direct, private connection between an on-premises data center and Google Cloud, offering high throughput and low latency, which aligns with the company's requirements and willingness to deploy physical infrastructure.
Why the other options are wrong
- A. Cloud Load Balancing distributes traffic across instances, it's not a solution for private data center connectivity.
- C. Cloud VPN creates an encrypted tunnel over the public internet, which may not meet the high throughput and low latency requirements of a direct private connection.
- D. Cloud CDN caches content closer to users to reduce latency for web content, not for private data center connectivity.
Cloud Interconnect
A Google Cloud networking service that provides a dedicated, high-bandwidth connection between an on-premises network and a Google Cloud VPC network, bypassing the public internet.
- Direct, private connection
- High throughput and low latency
- Available as Dedicated Interconnect (direct physical cable) or Partner Interconnect (via a service provider)
- Reduces egress costs compared to VPN over public internet
