Google Cloud Digital LeaderSecurity and operations with Google CloudHard
A company is migrating its legacy applications to Google Cloud, some of which require strict latency and bandwidth guarantees for their on-premises to cloud connectivity. They need a dedicated, private connection with higher throughput and lower latency than a VPN, bypassing the public internet entirely. Which Google Cloud service should they use for this type of connectivity?
- ACloud DNS
- BCloud Interconnect (Dedicated Interconnect)
- CCloud CDN
- DCloud VPN (HA VPN)
Show answer & explanationAnswer & explanation
Correct answer: B. Cloud Interconnect (Dedicated Interconnect)
Dedicated Interconnect provides a direct, private physical connection between an on-premises network and Google Cloud, offering higher bandwidth, lower latency, and more consistent performance than VPN over the public internet.
Why the other options are wrong
- A. Cloud DNS provides domain name resolution, unrelated to network connectivity solutions.
- C. Cloud CDN caches content closer to users for faster delivery, not for private network connectivity from on-premises.
- D. Cloud VPN provides encrypted tunnels over the public internet, which doesn't guarantee latency or bandwidth and routes over public networks.
Cloud Interconnect (Dedicated)
Dedicated Interconnect provides a direct, physical connection between your on-premises network and Google's network, offering high bandwidth and lower latency.
- Establishes a private connection, bypassing the public internet.
- Offers higher throughput and more consistent latency than VPN.
- Requires physical presence at a Google-supported colocation facility.
- Ideal for hybrid cloud architectures with strict performance needs.
Memory trick: Dedicated Interconnect is your private, express lane to the cloud.
