Designing and planning a cloud solution architecture

Your company is creating a new architecture to support its data-focused business strategy. You are responsible for configuring the network. Your company’s mobile and web-facing applications will be deployed on-premises, while all data analysis will take place in GCP. The plan is to process and load 7 years of archived .csv files totaling 900 TB of data, and then continue loading 10 TB of data each day. You currently have an existing 100-MB internet connection.

Which actions will meet your company’s needs?

  • A Compress and upload both archived files and files uploaded daily using the gsutil ג€"m option.
  • B Lease a Transfer Appliance, upload archived files to it, and send it to Google to transfer archived data to Cloud Storage. Establish a connection with Google using a Dedicated Interconnect or Direct Peering connection and use it to upload files daily.
  • C Lease a Transfer Appliance, upload archived files to it, and send it to Google to transfer archived data to Cloud Storage. Establish one Cloud VPN Tunnel to VPC networks over the public internet, and compress and upload files daily using the gsutil ג€"m option.
  • D Lease a Transfer Appliance, upload archived files to it, and send it to Google to transfer archived data to Cloud Storage. Establish a Cloud VPN Tunnel to VPC networks over the public internet, and compress and upload files daily.
Explanation

Transfer Appliance is designed to securely ship high-capacity data to Google for upload to Cloud Storage, making it suitable for a 900 TB historical backlog. A 100 Mbps internet connection cannot sustain a 10 TB daily transfer; an enterprise-grade Dedicated Interconnect or Direct Peering connection provides the substantially higher network capacity required for ongoing uploads. A Cloud VPN tunnel over the public internet does not remove the underlying internet-bandwidth limitation.
