# CreateDBCluster
<a name="API_CreateDBCluster"></a>

Creates a new Amazon Aurora DB cluster or Multi-AZ DB cluster.

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 [CreateDBInstance](https://docs.aws.amazon.com/AmazonRDS/latest/APIReference/API_CreateDBInstance.html) 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.

You can use the `ReplicationSourceIdentifier` 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 [What is Amazon Aurora?](https://docs.aws.amazon.com/AmazonRDS/latest/AuroraUserGuide/CHAP_AuroraOverview.html) in the *Amazon Aurora User Guide*.

You can also use the `ReplicationSourceIdentifier` 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 [Multi-AZ DB cluster deployments](https://docs.aws.amazon.com/AmazonRDS/latest/UserGuide/multi-az-db-clusters-concepts.html) in the *Amazon RDS User Guide*.

You can use the `WithExpressConfiguration` parameter to create an Aurora DB Cluster with express configuration and create cluster in seconds. Express configuration provides a cluster with a writer instance and feature specific values set to all other input parameters of this API.

+  `KmsKeyId` - The AWS KMS key identifier for the KMS key to use to encrypt the copy of the DB cluster in the destination AWS Region. This should refer to the same KMS key for both the `CreateDBCluster` operation that is called in the destination AWS Region, and the operation contained in the presigned URL.
+  `DestinationRegion` - The name of the AWS Region that Aurora read replica will be created in.
+  `ReplicationSourceIdentifier` - The DB cluster identifier for the encrypted DB cluster to be copied. This identifier must be in the Amazon Resource Name (ARN) format for the source AWS Region. For example, if you are copying an encrypted DB cluster from the us-west-2 AWS Region, then your `ReplicationSourceIdentifier` would look like Example: `arn:aws:rds:us-west-2:123456789012:cluster:aurora-cluster1`.
To learn how to generate a Signature Version 4 signed request, see [ Authenticating Requests: Using Query Parameters (AWS Signature Version 4)](https://docs.aws.amazon.com/AmazonS3/latest/API/sigv4-query-string-auth.html) and [ Signature Version 4 Signing Process](https://docs.aws.amazon.com/general/latest/gr/signature-version-4.html).  
If you are using an AWS SDK tool or the AWS CLI, you can specify `SourceRegion` (or `--source-region` for the AWS CLI) instead of specifying `PreSignedUrl` manually. Specifying `SourceRegion` autogenerates a presigned URL that is a valid request for the operation that can run in the source AWS Region.
Valid for Cluster Type: Aurora DB clusters only  
Type: String  
Required: No

 ** PubliclyAccessible **   
Specifies whether the DB cluster is publicly accessible.  
Valid for Cluster Type: Multi-AZ DB clusters only  
When the DB cluster is publicly accessible and you connect from outside of the DB cluster's virtual private cloud (VPC), its domain name system (DNS) endpoint resolves to the public IP address. When you connect from within the same VPC as the DB cluster, the endpoint resolves to the private IP address. Access to the DB cluster is controlled by its security group settings.  
When the DB cluster isn't publicly accessible, it is an internal DB cluster with a DNS name that resolves to a private IP address.  
The default behavior when `PubliclyAccessible` is not specified depends on whether a `DBSubnetGroup` is specified.  
If `DBSubnetGroup` isn't specified, `PubliclyAccessible` defaults to `true`.  
If `DBSubnetGroup` is specified, `PubliclyAccessible` defaults to `false` unless the value of `DBSubnetGroup` is `default`, in which case `PubliclyAccessible` defaults to `true`.  
If `PubliclyAccessible` is true and the VPC that the `DBSubnetGroup` is in doesn't have an internet gateway attached to it, Amazon RDS returns an error.
