Which solution will migrate the database MOST cost-effectively?
Order an AWS Snowball Edge Storage Optimized device. Use AWS Database Migration Service (AWS DMS) with AWS Schema Conversion Tool (AWS SCT) to migrate the database with replication of ongoing changes. Send the Snowball Edge device to AWS to finish the migration and continue the ongoing replication.
Order an AWS Snowmobile vehicle. Use AWS Database Migration Service (AWS DMS) with AWS Schema Conversion Tool (AWS SCT) to migrate the database with ongoing changes. Send the Snowmobile vehicle back to AWS to finish the migration and continue the ongoing replication.
Order an AWS Snowball Edge Compute Optimized with GPU device. Use AWS Database Migration Service (AWS DMS) with AWS Schema Conversion Tool (AWS SCT) to migrate the database with ongoing changes. Send the Snowball device to AWS to finish the migration and continue the ongoing replication
Order a 1 GB dedicated AWS Direct Connect connection to establish a connection with the data center. Use AWS Database Migration Service (AWS DMS) with AWS Schema Conversion Tool (AWS SCT) to migrate the database with replication of ongoing changes.
Explanations:
Snowball Edge Storage Optimized offers cost-effective, high-capacity data transfer. DMS and SCT enable ongoing replication during migration, minimizing downtime.
Snowmobile is overkill for a 20 TB migration and is intended for much larger data transfers. It is also more expensive than necessary.
Snowball Edge Compute Optimized with GPU is unnecessary for this migration. The compute capability and GPU are not required for data transfer, making it more costly.
A 1 GB Direct Connect connection is too slow for 20 TB of data in 2 weeks. The bandwidth would not support the required migration speed efficiently.
I have a feeling that the answer is:
Order an AWS Snowball Edge Storage Optimized device. Use AWS Database Migration Service (AWS DMS) with AWS Schema Conversion Tool (AWS SCT) to migrate the database with replication of ongoing changes. Send the Snowball Edge device to AWS to finish the migration and continue the ongoing replication.
