Zorluk: OrtaDesigning Migration Plans and Data Transfer Strategies

An industrial equipment manufacturer needs to migrate 50 TB50\text{ TB} of unstructured binary firmware archives from on-premises network-attached storage (NAS) to Cloud Storage. The company maintains an existing 1 Gbps1\text{ Gbps} Dedicated Interconnect connection to Google Cloud, with 700 Mbps700\text{ Mbps} of available bandwidth dedicated to the transfer. Corporate security policy dictates that data must be transferred strictly over private networking without traversing the public internet, and the migration must complete in under 88 days. Which data transfer architecture should you recommend?

  1. Deploy Storage Transfer Service on-premises agents within the local network to transfer the files directly to Cloud Storage via private Google access over the Dedicated Interconnect.Cevap
  2. B
    Order a Google Cloud Transfer Appliance, copy the 50 TB payload locally, and ship the physical appliance to a Google data center for ingestion.
  3. C
    Configure an IPsec HA VPN tunnel over the public internet and run parallel gsutil rsync commands from on-premises servers to the destination bucket.
  4. D
    Configure VPC Network Peering directly between the on-premises storage network and the target GCP VPC to mount the NAS directly on Compute Engine VMs.

Cevap

Deploy Storage Transfer Service on-premises agents within the local network to transfer the files directly to Cloud Storage via private Google access over the Dedicated Interconnect.
Storage Transfer Service agents installed on-premises efficiently orchestrate scale-out file reads and stream them directly over Private Google Access via the existing Dedicated Interconnect. Based on the available 700 Mbps bandwidth, 50 TB transfers in roughly 6.6 days, satisfying both the 8-day deadline and the strict private networking requirement.

Adım Adım Çözüm

1
Calculate network throughput and required transfer time
Converting 50 TB50\text{ TB} to bits yields 50×1,000×8=400,000 Gb50 \times 1,000 \times 8 = 400,000\text{ Gb}. At 700 Mbps700\text{ Mbps} (0.7 Gbps0.7\text{ Gbps}), total transfer time is 400,0000.7≈571,428 seconds≈6.61 days\frac{400,000}{0.7} \approx 571,428\text{ seconds} \approx 6.61\text{ days}.
Verifies that online data transfer over the existing connection fits comfortably inside the 8-day deadline.
2
Evaluate network route and security constraints
Using Storage Transfer Service on-premises agents routes traffic through the Dedicated Interconnect using Private Google Access endpoints.
Satisfies the security requirement that data must not traverse the public internet.
3
Compare online transfer efficiency against offline hardware appliance options
Online transfer completes in approximately 6.6 days automatically, whereas ordering and shipping a Transfer Appliance adds logistics latency.
Confirms Storage Transfer Service over Cloud Interconnect is the optimal architectural selection.
