If you’re happy paying a few dollars per hour for a managed solution, don’t need more than 2000-3000 read/write operations per second on average, stick with DynamoDB. If you need “extreme performance” and/or more advanced setups like cross-region replication it’s likely more beneficial to manage your own Cassandra cluster.
