Step 9. Configure Network and Availability Settings

In this article

    [This step is available if you have selected the Restore to a new location, or with different settings option at the Restore Mode step of the wizard.]

    At the Network step of the wizard, configure availability settings and network settings such as Amazon VPCs, subnet groups and security groups:

    1. To configure network settings, in the RDS instance list, select the necessary RDS instances and click Customize. In the Amazon VPC window, do the following:
    1. From the Amazon VPC drop-down list, select a VPC where the restored RDS instances will be launched.

    For a VPC to be displayed in the drop-down list, it must be created in advance as described in the Working with VPCs and subnets section in the AWS documentation.

    1. From the Subnet group drop-down list, select a subnet group where the restored RDS instances will reside.

    For a subnet group to be displayed in the drop-down list, it must be created in advance as described in the Working with VPCs and subnets section in the AWS documentation.

    1. From the Security group drop-down list, select a security group that will be associated with the restored instances.

    For a security group to be displayed in the drop-down list, it must be created in advance as described in the Working with security groups section in the AWS documentation.

    1. In the Database port field, specify a port number which can be used to access the RDS instances.

    The port range for all engines must be 1150–65535. For SQL, the port range must be 1150–65535 except for 1234, 1434, 3260, 3343, 3389, 47001 and 49152–49156.

    1. Click OK.

    Note

    You are able to select only those subnet groups and security groups that are created in the selected Amazon VPC.

    1. To configure availability settings, in the RDS instance list, select the necessary RDS instances and click Availability. In the Availability Settings window, do the following:
    1. From the Public access drop-down list, select one of the following options:
    • Select Disabled if you want the selected instances to have only private IP addresses — that is, the instances will be accessible only within the selected VPC.
    • Select Enabled if you want the instances to have public IP addresses in addition to private IP addresses — that is, the instances will be accessible from the internet.

    Note

    To allow public access to an RDS instance, the security group of the instance must allow public access.

    1. From the Availability type drop-down list, select one of the following options:
    • Select Single zone if you want the restored RDS instances to run in a single availability zone. Then select the necessary availability zone from the Availability zone drop-down list. In the drop-down list, you will see those availability zones in which subnets from the selected subnet group reside.
    • Select Multiple zone if you want the restored RDS instances to run in one availability zone and to be replicated to another availability zone — that is, if you want the restored RDS instances to run in a Multi-AZ deployment. For more information on the Multi-AZ deployment, see High availability (Multi-AZ) for Amazon RDS.

    Note

    Multi-AZ deployment is not available for RDS instances running Microsoft SQL Server Express or Microsoft SQL Server Web editions.

    1. Click OK.
