What is the MOST cost-effective mechanism to move this data and meet the migration deadline?
Use AWS Snowmobile to ship the data to AWS.
Order multiple AWS Snowball devices to ship the data to AWS.
Enable Amazon S3 Transfer Acceleration and securely upload the data.
Create an Amazon S3 VPC endpoint and establish a VPN to upload the data.
Explanations:
AWS Snowmobile is designed for large-scale data transfers (up to 100 PB) but is not practical for 150 TB given the short timeframe and logistical challenges involved in scheduling and transporting such a large vehicle.
Ordering multiple AWS Snowball devices is the most cost-effective option for transferring 150 TB of data within the one-month deadline. Snowball can securely transfer data at much higher speeds than the current 100 Mbps connection, making it ideal for this migration.
While Amazon S3 Transfer Acceleration can speed up data uploads over the internet, the current network limitation of 100 Mbps at night would still result in a lengthy transfer time, likely exceeding the one-month deadline for 150 TB of data.
Creating an Amazon S3 VPC endpoint and establishing a VPN for data transfer does not increase upload speeds significantly beyond the current limit of 100 Mbps, making it unsuitable for completing the transfer within the required timeframe.
I opine that the answer is:
Order multiple AWS Snowball devices to ship the data to AWS.
