Difficulty: EasyDesigning Migration Plans and Data Transfer Strategies

A financial services organization needs to transfer 500 TB of static unstructured archival data from their on-premises network attached storage (NAS) to a Cloud Storage bucket in Google Cloud. The organization has a dedicated 10 Gbps Cloud Interconnect line with available bandwidth and requires an automated online transfer mechanism that performs data integrity checks without sending physical hardware. Which Google Cloud service should the cloud architect recommend?

  2. B
    Transfer Appliance
  3. C
    Cloud Spanner
  4. D
    HA VPN with Cloud Routers

Answer

The cloud architect should recommend Storage Transfer Service.
Storage Transfer Service is the recommended Google Cloud solution for online data transfers of large datasets from on-premises storage systems to Cloud Storage over available high-speed network connectivity. It automates file copy, scaling, and checksum validation.

Step-by-Step Solution

1
Identify the data volume, source/destination, and network constraints.
500 TB of unstructured files need to be moved online from on-premises NAS to Cloud Storage over an existing 10 Gbps Cloud Interconnect.
The bandwidth (10 Gbps) is sufficient to perform an online transfer, eliminating the need for physical media delivery.
2
Evaluate Google Cloud data transfer options.
Storage Transfer Service provides managed, secure, scale-out online data movement for on-premises file data directly into Cloud Storage.
It natively handles automatic retries, checksum validation, and scheduling without manual script maintenance.
