AWS Aurora

What is Amazon Aurora? - Amazon AuroraAmazon Aurora

• Aurora takes advantage of RDS features for management and administration.

• Aurora management operations typically involve entire clusters of database instances that are syncronized through replication.

  • The automatic clustering, replication and storage allocation make it simple and cost-effective to set up, operate and scale.

• 1/10th the cost of commercial database.

  • You are only charged for the space that you use in an Aurora cluster volume.

Aurora Data

Aurora data is stored in the cluster volume, which is a single, virtual volume that uses SSDs.

• A cluster volume consists of copies of the data across three AZs in a single Region.

This data is automatically replicated. Aurora also supports failover.

This architecture makes your data independent from the DB instances in the cluster.

• So you can delete an instance from the cluster and have 0 data loss.

• Aurora only erases the data if you delete the entire cluster.

Also cluster volumes automatically grow as the amount of data increases.

Supported Engines

MySQL
PostgreSQL

DB Instance Classes

Like RDS you can choose different instance classes for different needs.

Basic Price Models

• You may choose a Serverless model, which automatically starts up or shutdown instances, and scales capacity up or down, based on needs. In this model you pay only for capacity consumed.

• You can choose Provisioned On-Demand instances and pay per DB instance-hour.

• You can also choose a Provisioned Reserved instances for additional savings.
