Does Amazon use DynamoDB?

Is Aurora serverless cheaper?

If you were to keep an Aurora Serverless database running 24 hours per day at 2 ACUs, it would cost you $2.88 ($0.06 * 2 * 24) per day (or roughly $86 per month). If you scale down to 1 ACU (on MySQL), the base cost (without and scale ups) would be about $43 per month.

What is the maximum amount of replicas that Aurora can have?

Yes, you can add up to 15 Aurora Replicas on each cross-region cluster, and they will share the same underlying storage as the cross-region replica. A cross-region replica acts as the primary on the cluster and the Aurora Replicas on the cluster will typically lag behind the primary by 10s of milliseconds.

Is DynamoDB a RDS?

DynamoDB is Amazon’s footprint in the NoSQL world. NoSQL databases are very different from traditional RDBMS in that they have a flexible data model where a “row” of data may not have the same number of attributes as the next row. Like RDS, Amazon DynamoDB is also a hosted and managed solution. …
