Zorluk: OrtaDesigning Migration Plans and Data Transfer Strategies

A financial analytics organization needs to transfer a 600 TB dataset from their on-premises storage array to a Google Cloud Storage bucket within a strict 14-day execution window. The organization already has an operational 10 Gbps Dedicated Interconnect connection to GCP, with 6 Gbps of unutilized bandwidth dedicated specifically for this data movement. High availability, automated retry handling, and minimal operational complexity are mandatory requirements. Which data transfer strategy should you recommend?

  1. Use Storage Transfer Service to transfer the dataset online directly over the existing Dedicated Interconnect connection.Cevap
  2. B
    Order a GCP Transfer Appliance to perform an offline data copy on-premises and ship the appliance to Google for ingestion.
  3. C
    Provision a new Cloud VPN gateway with HA VPN tunnels over the public internet to stream the dataset into Cloud Storage.
  4. D
    Migrate the raw dataset into Cloud Spanner instances using Cloud Dataflow pipelines to enforce default data security policies.

Cevap

Use Storage Transfer Service to perform an online data transfer directly over the existing Dedicated Interconnect connection.
Transferring 600 TB over an available 6 Gbps Dedicated Interconnect pipeline takes approximately 9.25 days, comfortably meeting the 14-day requirement. Storage Transfer Service automates object validation, retries, and lifecycle management without physical shipping overhead.

Adım Adım Çözüm

1
Calculate required transfer throughput and time for the 600 TB dataset
600 TB equals 4,800,0004,800,000 Gb. At an available network speed of 6 Gbps6\text{ Gbps}, total transfer time is 4,800,0006=800,000 seconds≈9.26 days\frac{4,800,000}{6} = 800,000\text{ seconds} \approx 9.26\text{ days}, well within the 14-day deadline.
Determining network transfer feasibility confirms whether online transfer meets the time constraint without physical media.
2
Select the appropriate managed data transfer service for existing hybrid network infrastructure
Storage Transfer Service provides scalable, managed data ingestion into Cloud Storage over Private Google Access via Dedicated Interconnect.
Storage Transfer Service offers enterprise features including bandwidth throttling, error logging, object validation, and automatic retries.
