AWS Database Migration Service (AWS DMS) helps you migrate databases to AWS easily and securely at a low cost. You only pay for your replication instances and any additional log storage. Each database migration instance includes storage sufficient for swap space, replication logs, and data cache for most replications and inbound data transfer is free.
When migrating databases to Amazon Aurora, Amazon Redshift, Amazon DynamoDB or Amazon DocumentDB (with MongoDB compatibility) you can use AWS DMS free for six months.
On-Demand Instances let you pay for database migration capacity by the hour with no long-term commitments. This frees you from the costs and complexities of planning, purchasing, and maintaining hardware, thus making the entire process quick and inexpensive. AWS Database Migration Service also supports continuous data replication. You have the option of enabling Multi-AZ that provides a replication stream that is fault tolerant through redundant replication servers.
AWS Database Migration Service currently supports the T2, T3, C4, C5, R4 and R5 instance classes. T2/T3 instances are low-cost standard instances designed to provide a baseline level of CPU performance with the ability to burst above the baseline. They are suitable for developing, configuring and testing your database migration process, and for periodic data migration tasks that can benefit from the CPU burst capability. C4, R4 and R5 instances are designed to deliver the highest level of processor performance and achieve significantly higher packet per second (PPS) performance, lower network jitter, and lower network latency. You should use C4 or R4/R5 instances if you are migrating large databases and are looking to minimize the migration time.
T3 CPU Credits
Each compute optimized (C4) or memory optimized (R4 and R5) instance type includes 100GB of GP2 network-attached storage for swap space, replication logs and data cache; each burstable performance (T2 and T3) instance type includes 50GB of GP2 network-attached storage. You can extend the included storage and pay the following storage rates if you want to store logs for a longer period of time.

All data transfer into AWS Database Migration Service is free, and data transferred between AWS Database Migration Service and databases in Amazon RDS and Amazon EC2 Instances in the same Availability Zone also is free. Standard AWS data transfer rates apply when you migrate your source database to a target database in a different Availability Zone, Region, or outside of AWS. Standard AWS data transfer rates are listed on the EC2 instance pricing page.
