You can use the AWS Server Migration Service to migrate your on-premises workloads to AWS at no charge.
- The AWS Server Migration Service creates a new EBS snapshot with every replication. You will incur additional charges for EBS snapshots. To prevent additional charges, delete snapshot copies you no longer need.
- The AWS Server Migration Service replicates server volumes from your on-premises environment to S3 temporarily and purges them from S3 right after creating EBS snapshots, incurring a transient charge for S3.
