So we've made it to service number three on our AWS high availability top 10. Elastic IP Addresses. Now, elastic IP addresses are public IP addresses that can be programatically mapped between instances within a region. They are associated with the AWS account, and not with a specific instance or lifetime of an instance. Elastic IP addresses can be used to work around host or availability zone failures by quickly remapping the address to another running instance, or a replacement instance, that was just started. To use an elastic IP address, you first allocate one to your account, and then associate it with your instance, or a network interface. You can allocate up to five elastic IP addresses fer VPC per region. If you need to increase this limit, you submit a request to AWS support. When you associate an elastic IP address with an instance, or its primary network interface, the instance's public IP address is released. You cannot reuse a public IP address. You can dissociate an elastic IP address from a resource and reassociate it with a different resource. A dissociated elastic IP address remains allocated to your account until you explicitly release it. There is a small hourly charge if an elastic IP address is not associated with a running instance or if it is associated with a stopped instance or an unattached network interface. This practice is to discourage people from reserving a large number of IP addresses. An elastic IP address is for use in a specific region only.
