What should a solutions architect do to meet these requirements?
Use AWS Snowball.
Use AWS DataSync.
Use a secure VPN connection.
Use Amazon S3 Transfer Acceleration.
Explanations:
AWS Snowball is designed for large data transfers and can handle the migration of large datasets efficiently. It allows physical shipment of data storage devices to AWS, overcoming network bandwidth limitations, making it suitable for transferring 20 TB of data within the 30-day time frame.
AWS DataSync is typically used for ongoing data transfers and syncs but relies on the existing network bandwidth. Given the limited 15 Mbps bandwidth and the time constraint, it may not be able to migrate 20 TB of data in time without exceeding the bandwidth limits.
A secure VPN connection is not ideal for transferring large amounts of data quickly due to limited bandwidth. It would take a significantly longer time to transfer 20 TB over a 15 Mbps connection while adhering to the 70% utilization limit, making it impractical to meet the 30-day deadline.
Amazon S3 Transfer Acceleration can speed up uploads to S3 by using Amazon CloudFront’s edge locations, but it still relies on the internet connection and may not provide sufficient speed to transfer 20 TB of data within the specified time frame, especially with limited bandwidth.
From what I’ve heard, the answer is:
Use AWS Snowball.
