A multinational corporation needs to establish secure, high-bandwidth connectivity between its on-premises data centers in Europe and Asia and its Google Cloud VPC networks. The solution must provide dedicated, low-latency connections, bypass the public internet, and support enterprise-grade service level agreements (SLAs). Which Google Cloud networking product should they choose?
- ADedicated Cloud Interconnect
- BDirect Peering
- CPartner Cloud Interconnect
- DCloud VPN
Show answer & explanationAnswer & explanation
Correct answer: A. Dedicated Cloud Interconnect
Dedicated Cloud Interconnect provides a direct physical connection between an on-premises network and Google's network. It offers high bandwidth (10/100 Gbps), low latency, bypasses the public internet, and supports enterprise-grade SLAs, making it ideal for multinational corporations with critical connectivity needs.
Why the other options are wrong
- B. Direct Peering is for exchanging internet traffic directly with Google at a peering location. It's meant for public internet traffic optimization and does not provide private connectivity to your VPC network or the dedicated, low-latency, SLA-backed connection needed for an on-premises data center integration.
- C. Partner Cloud Interconnect also provides private connectivity but uses a supported service provider to connect your on-premises network to Google Cloud. While it offers similar benefits to Dedicated Interconnect, the 'Dedicated' option gives the most direct control and is typically chosen by large enterprises that can meet the technical requirements for direct cross-connects.
- D. Cloud VPN establishes encrypted tunnels over the public internet. It does not provide dedicated bandwidth, bypass the public internet, or offer the same latency guarantees and SLAs as a direct physical connection.
Dedicated Cloud Interconnect
Dedicated Cloud Interconnect provides direct physical connections between an on-premises network and Google's network. It offers high-bandwidth, low-latency, private connectivity that bypasses the public internet, suitable for enterprise-grade workloads requiring strong SLAs.
- Direct physical connection to Google's network
- High bandwidth (10 Gbps or 100 Gbps links)
- Low latency and consistent network performance
- Bypasses the public internet, enhancing security
- Supports enterprise-grade SLAs
- Ideal for hybrid cloud deployments and large data transfers
Memory trick: Dedicated Interconnect dedicates a direct line to the cloud.
