Google Associate Cloud EngineerEnsuring successful operation of a cloud solutionMedium
A network administrator needs to establish a secure and highly available connection between their on-premises data center and a Google Cloud Virtual Private Cloud (VPC) network. The connection requires low latency and high throughput for critical business applications. Which Google Cloud networking product should be recommended?
- AVPC Peering
- BShared VPC
- CCloud VPN
- DCloud Interconnect
Show answer & explanationAnswer & explanation
Correct answer: D. Cloud Interconnect
Cloud Interconnect provides direct, high-bandwidth connections between on-premises networks and Google Cloud, offering lower latency and higher throughput compared to VPN over the public internet, which is ideal for critical business applications requiring premium network performance.
Why the other options are wrong
- A. VPC Peering connects two VPC networks within Google Cloud; it does not connect on-premises networks to Google Cloud.
- B. Shared VPC allows multiple projects to use a common VPC network within Google Cloud; it does not provide connectivity between on-premises and Google Cloud.
- C. Cloud VPN provides secure IPsec tunnels over the public internet. While secure, it typically offers lower throughput and higher latency compared to dedicated connections, which might not meet the 'low latency and high throughput' requirement for critical applications.
Cloud Interconnect
A Google Cloud networking service that provides direct, high-bandwidth, low-latency connections between an on-premises data center and Google Cloud VPC networks.
- Dedicated connectivity to Google Cloud
- Higher bandwidth and lower latency than VPN over public internet
- Offers both Dedicated Interconnect and Partner Interconnect options
- Ideal for hybrid cloud environments with critical workloads
Memory trick: Interconnect is the 'direct highway' to the cloud, VPN is the 'scenic route'.
