<p>Creates a new Amazon Aurora DB cluster or Multi-AZ DB cluster.</p> <p>If you create an Aurora DB cluster, the request creates an empty cluster. You must explicitly create the writer instance for your DB cluster using the <a href="https://docs.aws.amazon.com/AmazonRDS/latest/APIReference/API_CreateDBInstance.html">CreateDBInstance</a> operation. If you create a Multi-AZ DB cluster, the request creates a writer and two reader DB instances for you, each in a different Availability Zone.</p> <p>You can use the <code>ReplicationSourceIdentifier</code> parameter to create an Amazon Aurora DB cluster as a read replica of another DB cluster or Amazon RDS for MySQL or PostgreSQL DB instance. For more information about Amazon Aurora, see <a href="https://docs.aws.amazon.com/AmazonRDS/latest/AuroraUserGuide/CHAP_AuroraOverview.html">What is Amazon Aurora?</a> in the <i>Amazon Aurora User Guide</i>.</p> <p>You can also use the <code>ReplicationSourceIdentifier</code> parameter to create a Multi-AZ DB cluster read replica with an RDS for MySQL or PostgreSQL DB instance as the source. For more information about Multi-AZ DB clusters, see <a href="https://docs.aws.amazon.com/AmazonRDS/latest/UserGuide/multi-az-db-clusters-concepts.html">Multi-AZ DB cluster deployments</a> in the <i>Amazon RDS User Guide</i>.</p>
