- AWS VPN connections and inter-region VPC peering connections are not able to connect to Aurora Serverless clusters.
How is Aurora different from RDS?
Unlike Amazon RDS for PostgreSQL, where high write workloads can severely impact replication, Aurora uses shared storage for writer and readers. As a result, all Aurora replicas are synced with the writer instance with minimal replica lag. The lag can be different for different replicas.
Does Aurora have automated backups?

What is difference between Aurora and Aurora Serverless?
Amazon Aurora and Aurora Serverless are two distinct products from AWS. While Amazon’s Aurora lets you use cloud-based computing resources to test and run your applications, the Aurora Serverless is a configuration that enables automated capacity scaling and for connecting applications.
How many connections can aurora handle?
16,000
You can increase the maximum number of connections to your Aurora MySQL DB instance by scaling the instance up to a DB instance class with more memory, or by setting a larger value for the max_connections parameter in the DB parameter group for your instance, up to 16,000.
Is Aurora Serverless scalable?
Aurora Serverless is an on-demand, auto-scaling configuration for Amazon Aurora that allows your database to scale capacity up or down based on your application’s needs.
Why is Aurora Faster than RDS?
RDS allows you to provision up to 5 replicas, and the process of replication is slower compared to Aurora. Aurora allows you to provision up to 15 replicas, and the replication is done in milliseconds. Aurora scales faster because it can add new read replicas quickly.
