Binding an EIP


You can bind an EIP to a DB instance for public accessibility and can unbind the EIP from the DB instance as required.


  • You need to configure security groups and enable specific IP addresses and ports to access the target DB instance. Before accessing the DB instance, you need to add an individual IP address or an IP address range that will access the DB instance to the inbound rule. For details, see section Configuring Security Group Rules.
  • Traffic generated by the public network is charged. You can unbind the EIP from the DB instance when the EIP is no longer used.
