  2. In the navigation pane, choose Subnet groups, and then choose Create subnet group.

  3. For Name, enter a unique name of your subnet group.

  4. For Description, enter a brief description of your subnet group.

  5. For VPC, choose a VPC that has at least one subnet in at least two Availability Zones.

    To connect to Amazon RDS databases, add public subnets into your subnet group. To connect to on-premises databases, add private subnets into your subnet group.
