Difficulty: HardDesigning Network Architecture and Hybrid Connectivity

A global aerospace engineering firm is designing a multi-tier hybrid network architecture to connect its on-premises data centers and remote manufacturing facilities to Google Cloud. Match each operational connectivity requirement on the left with the appropriate Google Cloud hybrid networking solution on the right.

  • Provisioning 100 Gbps private, unencrypted bandwidth between a primary research data center and a VPC network with a 99.99% availability SLA requiring redundant circuits across two edge availability domains.Dedicated Interconnect
  • Establishing an encrypted IPsec connection over the public internet with a 99.99% availability SLA for a regional distribution facility.HA VPN with dual gateways and active-active tunnels
  • Connecting a remote manufacturing plant requiring 200 Mbps sub-1G capacity where direct physical colocation with a Google edge facility is unavailable, leveraging a supported service provider.Partner Interconnect
  • Dynamically exchanging BGP routes to establish automatic topology updates and failover paths between on-premises routers and VPC subnets.Cloud Router

Answer

Matching pairs: Dedicated Interconnect satisfies 100 Gbps private connectivity with a 99.99% SLA across edge availability domains; HA VPN with dual gateways satisfies encrypted public internet connectivity with a 99.99% SLA; Partner Interconnect satisfies sub-1 Gbps connectivity via a service provider; Cloud Router satisfies dynamic BGP route exchange.
Each operational requirement strictly maps to its corresponding Google Cloud networking component based on bandwidth thresholds, SLA guarantees, encryption needs, and service provider integration.

Step-by-Step Solution

1
Analyze high-bandwidth and physical direct connection requirements.
Requirements of 100 Gbps direct private connection with a 99.99% SLA align specifically with Dedicated Interconnect deployed across two edge availability domains.
Dedicated Interconnect directly links the enterprise facility to Google's edge colocation using 10 Gbps or 100 Gbps physical circuits.
2
Analyze encrypted public IPsec connectivity requirements with a 99.99% availability SLA.
Requires HA VPN featuring dual VPN gateways and active-active tunnels.
Classic VPN does not offer a 99.99% SLA; HA VPN is explicitly engineered to provide 99.99% availability over IPsec.
3
Analyze low-bandwidth service provider connectivity requirements.
Sub-1 Gbps capacity (200 Mbps) through an ISP service provider maps to Partner Interconnect.
Partner Interconnect allows connection through third-party service providers when direct connection facilities are inaccessible or bandwidth needs are under 1 Gbps.
4
Analyze dynamic routing requirements.
BGP dynamic route exchange maps to Cloud Router.
Cloud Router automates route propagation using BGP across hybrid interconnects and VPN tunnels.

Key Concept

Architecting Google Cloud hybrid connectivity options (Dedicated Interconnect, Partner Interconnect, HA VPN, Cloud Router) based on SLA, bandwidth, encryption, and service provider integration.
