AWS Database Migration Service (AWS DMS) and the AWS Schema Conversion Tool (AWS SCT) make it easier for you to migrate your Apache Cassandra NoSQL databases to Amazon DynamoDB. Using AWS DMS and the AWS SCT, you can now migrate your Cassandra databases to DynamoDB and then replicate ongoing changes to your DynamoDB tables. After you have migrated a Cassandra database, you can benefit from the consistent, single-digit millisecond latency at any scale of DynamoDB.

Migrating from Cassandra to DynamoDB enables developers to focus on building products rather than managing and maintaining database infrastructure. The DynamoDB serverless provisioning model eliminates the need to overprovision database infrastructure. In addition, DynamoDB does not require specialized resourcing or licensing. As a result, customers run their DynamoDB-backed applications with up to a 70% TCO savings compared with Cassandra. Finally, DynamoDB global tables, backup and restore, and encryption at rest provide developers similar functionality as Cassandra, but with the benefits of these capabilities being easier to implement and without overhead or downtime.
