AWS Database Migration Service Pricing vs NoSQLSync

What AWS DMSactually charges for, what drives the bill up, and how it stacks up against NoSQLSync's flat monthly plans.

AWS DMS's pricing tiers

On-Demand, Single-AZPer-instance hourly (e.g. dms.t3.micro up to larger compute-optimized classes)
Hourly compute + storage + data transfer
No flat plan — you choose and pay for a replication instance size directly
On-Demand, Multi-AZRoughly 2x the Single-AZ hourly rate
Same instance-hour model
Adds redundancy at roughly double the compute and storage cost
DMS ServerlessPer DCU-hour, auto-scaling
Usage-based, no instance sizing required
Capacity scales automatically with load instead of picking an instance class
Free tierTime/credit-limited
750 hrs/month of dms.t3.micro + 50 GB storage for 12 months (older accounts) or AWS credits (newer accounts)
Terms changed as of July 2025 — verify current terms on the AWS free-tier page

Instance-hour pricing model per aws.amazon.com/dms/pricing — exact current $/hr figures should be checked against the AWS Pricing Calculator before quoting a number, since the rate table changes and wasn't independently re-verified line-by-line here.

What actually drives the bill up

▲You pay for the replication instance by the hour regardless of whether data is actively moving — the wrong instance size means paying for idle compute.
▲Storage (a base allotment per instance class, more billed at standard EBS rates) is a second line item beyond compute.
▲Data transfer is free within the same AWS AZ/region but follows standard AWS egress pricing across AZs, regions, or outside AWS.
▲Multi-AZ deployments roughly double both compute and storage cost for redundancy.

How NoSQLSync compares

✓NoSQLSync has one flat monthly price per tier; AWS DMS requires picking and sizing a specific replication instance class plus separately accounting for storage and egress.
✓NoSQLSync supports DynamoDB as a source; AWS DMS does not support DynamoDB as a migration source at all — a functional gap as much as a pricing one for teams on DynamoDB.
✓NoSQLSync works with any cloud or self-hosted database; AWS DMS's pricing and mechanics are AWS-native only.

Frequently asked questions

How much does a small AWS DMS migration cost?

It depends heavily on instance size, Multi-AZ choice, and how long the replication instance stays provisioned — model it in the AWS Pricing Calculator for your exact instance class rather than relying on a rule of thumb.

Does AWS DMS charge for the data itself?

Not directly for in-AWS, same-region transfer, but standard AWS data-transfer rates apply once data crosses AZs, regions, or leaves AWS.
