Difficulty: HardDesigning Network Architecture and Hybrid Connectivity

Match each hybrid cloud enterprise networking scenario to the most appropriate Google Cloud connectivity solution.

  • A fintech enterprise requires a dedicated 10 Gbps private connection from its primary data center to GCP with a 99.99% availability SLA, requiring redundant physical circuits terminating across two distinct colocation metros.Dedicated Interconnect provisioned with dual 10 Gbps links across two edge availability domains in two distinct metro locations.
  • A healthcare provider needs an encrypted connection between a small regional clinic and a GCP VPC over the public internet with a 99.99% SLA using dynamic routing.HA VPN with active-active IPsec tunnels using dynamic BGP routing via Cloud Router.
  • A retail company requires a private, SLA-backed 500 Mbps connection between its data center and GCP without placing its own equipment in a Google colocation facility.Partner Interconnect provisioned through a supported service provider at sub-10 Gbps capacity.
  • A global logistics firm needs to establish dynamic BGP route exchange and centralized transit connectivity between multiple geographically dispersed VPCs and on-premises branch sites.Network Connectivity Center (NCC) utilizing Cloud Router and VPC spokes for hub-and-spoke transit networking.

Answer

The correct pairings match each scenario to its required bandwidth, SLA, and topology model: 1) Fintech high-bandwidth 99.99% SLA requires Dedicated Interconnect across two metros; 2) Healthcare clinic requiring IPsec encryption and 99.99% SLA uses HA VPN with dynamic Cloud Router; 3) Retail sub-10 Gbps connectivity without custom colocation hardware uses Partner Interconnect; 4) Logistics dynamic transit routing across VPCs and sites uses Network Connectivity Center.
Each scenario directly maps to the architectural capabilities of GCP hybrid networking products: Dedicated Interconnect is required for unencrypted 10 Gbps direct connections with 99.99% SLA; HA VPN provides encrypted internet connectivity at 99.99% SLA; Partner Interconnect supports sub-10 Gbps private connection through service providers; Network Connectivity Center enables transit routing across hybrid spokes.

Step-by-Step Solution

1
Analyze bandwidth and colocation requirements for high-capacity hybrid connectivity.
Direct 10 Gbps physical circuits without intermediate provider infrastructure mandate Dedicated Interconnect. Meeting 99.99% availability requires 4 VLAN attachments across 2 metros.
Dedicated Interconnect is designed for 10 Gbps/100 Gbps enterprise requirements direct to Google edge locations.
2
Identify secure, internet-based connectivity options meeting high availability standards.
HA VPN with dual active IPsec interfaces and Cloud Router dynamic routing provides 99.99% SLA over public internet.
Classic VPN only provides 99.9% SLA, whereas HA VPN topology guarantees 99.99% availability.
3
Evaluate options for sub-10 Gbps private connectivity without direct colocation access.
Partner Interconnect enables connection speeds from 50 Mbps up to 10 Gbps through a third-party network provider.
Dedicated Interconnect does not support sub-10 Gbps allocations like 500 Mbps.
4
Select central management architecture for enterprise transit connectivity.
Network Connectivity Center acts as a centralized management hub for global VPC and hybrid transit traffic using BGP spokes.
Standard VPC Peering is non-transitive, so transit routing requires Network Connectivity Center.

Key Concept

Selecting and architecting appropriate Google Cloud hybrid connectivity options (Dedicated Interconnect, Partner Interconnect, HA VPN, and Network Connectivity Center) based on bandwidth, SLA, encryption, and routing requirements.
