Which of the following solutions would enable the company to migrate the workload to AWS and meet all of the requirements?
Use a multi-part upload in Amazon S3 client to parallel-upload the data to the Amazon S3 bucket over the Internet. Use the throttling feature to ensure that the Amazon S3 client does not use more than 30 percent of available Internet capacity.
Request an AWS Snowmobile with 1 PB capacity to be delivered to the data center. Load the data into Snowmobile and send it back to have AWS download that data to the Amazon S3 bucket. Sync the new data that was generated while migration was in flight.
Use an Amazon S3 client to transfer data from the data center to the Amazon S3 bucket over the Internet. Use the throttling feature to ensure the Amazon S3 client does not use more than 30 percent of available Internet capacity.
Request multiple AWS Snowball devices to be delivered to the data center. Load the data concurrently into these devices and send it back. Have AWS download that data to the Amazon S3 bucket. Sync the new data that was generated while migration was in flight.
Explanations:
While using a multi-part upload with throttling could facilitate uploading data over the Internet, the bandwidth limitation (30% of 1 Gbps) would significantly slow down the migration process, making it impractical to move 400 TB in 10 days.
AWS Snowmobile is designed for very large data migrations (up to 1 PB), but it requires extensive planning and time to arrange for delivery and return. Given the 10-day deadline, this option is not feasible due to logistics and time constraints.
Similar to option A, using an Amazon S3 client over the Internet with throttling would not provide sufficient bandwidth to transfer 400 TB in the given timeframe, thus making it impractical.
Requesting multiple AWS Snowball devices allows for a more efficient and faster transfer of large data volumes. Snowball devices can be loaded concurrently, and the logistics of sending and returning them are manageable within the 10-day period. Additionally, after the initial migration, syncing any new data can be done over the Internet, making this option the most suitable for the requirements.
If memory serves me right, the answer is:
Request multiple AWS Snowball devices to be delivered to the data center. Load the data concurrently into these devices and send it back. Have AWS download that data to the Amazon S3 bucket. Sync the new data that was generated while migration was in flight.
