Migrate on-prem data: 200 TB of SAN video files, a Redshift data warehouse, and 20 GB of PNGs in S3. Load videos into a Cloud Storage bucket, warehouse data into BigQuery, and PNGs into another Cloud Storage bucket without writing code. What should you use?

Transfer Appliance is ideal for migrating 200 TB of on-premises video files, as it's designed for large-scale offline data transfers where network bandwidth is a constraint. BigQuery Data Transfer Service is the native solution for migrating data from Redshift to BigQuery, offering automated and managed transfers. Storage Transfer Service is suitable for moving data between S3 and Cloud Storage buckets, especially for the 20 GB of PNGs, as it handles transfers efficiently without requiring custom code. Incorrect options: gcloud storage is a command-line tool, not suitable for 200 TB offline transfers. Dataflow is for data processing, not direct data warehouse migration. Storage Transfer Service is not optimal for 200 TB from on-premises; it's primarily for online transfers between cloud providers or within Google Cloud. Cloud Data Fusion is an integration service, not a direct migration tool for large-scale offline data or direct S3 to Cloud Storage transfers.
