Zorluk: OrtaDesigning Network Architecture and Hybrid Connectivity

A global financial payment processor is connecting its on-premises transactional ledger database to a Google Cloud Virtual Private Cloud (VPC) hosting analytical microservices. The connection requires low-latency, a guaranteed minimum capacity of 12 Gbps, and an SLA of 99.99% availability. Which hybrid connectivity architecture should the Cloud Architect recommend?

  1. Provision four Dedicated Interconnect connections distributed across two separate locations (metropolitan areas) and two edge availability domains per location, paired with Cloud Routers running BGP.Cevap
  2. B
    Deploy dual HA VPN gateways with four active IPsec tunnels using Cloud Router BGP dynamic routing to aggregate bandwidth up to 12 Gbps.
  3. C
    Establish a VPC Network Peering connection directly between the on-premises network gateway and the Google Cloud VPC network with dynamic route exchange.
  4. D
    Provision a single 100 Gbps Partner Interconnect connection using an HA VPN tunnel as a secondary backup path to satisfy the 99.99% SLA.

Cevap

Provision four Dedicated Interconnect connections distributed across two separate locations (metropolitan areas) and two edge availability domains per location, paired with Cloud Routers running BGP.
For mission-critical applications requiring 99.99% availability and continuous bandwidth exceeding 10 Gbps, Google Cloud specifies a topology consisting of four Dedicated Interconnect circuits across two different locations (metropolitan areas) and two edge availability domains per location. Dynamic BGP routing managed by Cloud Routers allows automatic traffic rerouting during domain or facility outages.

Adım Adım Çözüm

1
Analyze hybrid connectivity throughput and SLA constraints.
The requirement specifies 12 Gbps capacity, low latency, and a 99.99% availability SLA.
Bandwidth requirements exceeding 10 Gbps combined with strict 99.99% uptime rule out standard Cloud VPN and single-location interconnect configurations.
2
Evaluate Google Cloud topology requirements for 99.99% availability.
99.99% availability for Dedicated Interconnect requires 2 connections in location 1 (EAD 1 & 2) and 2 connections in location 2 (EAD 1 & 2).
This redundant design ensures fault tolerance against edge availability domain failures and entire metropolitan area outages.
3
Select the option that configures multi-location redundant Dedicated Interconnect connections with Cloud Router BGP.
The architecture using four Dedicated Interconnect circuits across two locations satisfies both the 12 Gbps bandwidth requirement and the 99.99% SLA.
This topology is the official Google Cloud recommended blueprint for production-critical hybrid infrastructure requiring maximum availability.
