Zorluk: OrtaDesigning Infrastructure for Business Requirements and Cost Optimization

An automotive telematics enterprise needs to establish hybrid connectivity between its on-premises data center and a Google Cloud VPC. The business requirement dictates a continuous, private Layer 3 connection with a bandwidth requirement of 8 Gbps for real-time telemetry streaming, without routing traffic over the public internet. The architecture must minimize ongoing connectivity and data transfer costs while fulfilling these bandwidth and security requirements. Which hybrid networking strategy should the cloud architect recommend?

  1. Provision a 10 Gbps Dedicated Interconnect connection to directly extend the on-premises network to Google Cloud.Cevap
  2. B
    Configure multiple HA VPN tunnels with Cloud Router BGP dynamic routing aggregated over the public internet.
  3. C
    Order a Google Cloud Transfer Appliance to transport daily telemetry data batches to Cloud Storage physically.
  4. D
    Deploy a multi-zone Google Kubernetes Engine cluster hosting custom software routers to compress and proxy traffic over public IP addresses.

Cevap

Provision a 10 Gbps Dedicated Interconnect connection to directly extend the on-premises network to Google Cloud.
Provisioning a 10 Gbps Dedicated Interconnect connection establishes a direct physical link between the on-premises facility and Google Cloud. It satisfies the 8 Gbps bandwidth requirement, keeps data off the public internet, and delivers optimal per-gigabyte transfer costs for high-volume continuous traffic.

Adım Adım Çözüm

1
Analyze security and networking transport constraints
Identified that traffic must remain on a private Layer 3 path without traversing the public internet.
Enterprise security policy strictly forbids routing telemetry streams across public IP endpoints.
2
Evaluate throughput requirements against GCP hybrid connectivity products
Determined that 8 Gbps continuous bandwidth exceeds the single-tunnel capacity of HA VPN (3 Gbps per tunnel).
High-throughput traffic exceeding 3 Gbps requires dedicated physical infrastructure rather than software VPN encryption over public networks.
3
Select the optimal cost and operational solution
A 10 Gbps Dedicated Interconnect link satisfies both the 8 Gbps bandwidth requirement and private routing constraint at the lowest per-gigabyte data transfer cost.
Dedicated Interconnect provides reliable high-bandwidth connectivity with lower ongoing network transfer costs for high-volume workloads.

Anahtar Kavram

Selecting hybrid connectivity (Dedicated Interconnect vs HA VPN) based on throughput limits, privacy requirements, and cost optimization.
