You pay only for the capacity your application consumes, and you can save up to 90% of your database cost compared to the cost of provisioning capacity for peak load. > Aurora Serverless v2 supports all manner of database workloads. Examples include development and test environments, websites, and applications that have infrequent, intermittent, or unpredictable workloads to the most demanding, business critical applications that require high scale and high availability. It supports the full breadth of Aurora features, including global database, Multi-AZ deployments, and read replicas. Aurora Serverless v2 is available for the Amazon Aurora MySQL-Compatible Edition and PostgreSQL-Compatible Edition. ## #OpenQuestions - Is it truly [[Serverless MOC|Serverless]] though? - Doesn't scale to zero as there's an always-on minimum cost.
