A cluster of Traffic Managers on EC2 can transfer Elastic IP Addresses from one to another if a Traffic Manager fails. Traffic distribution is configured by means of Traffic IP groups, as defined on the **Services > Traffic IP Groups** page of the Admin UI.

This chapter highlights the differences in traffic distribution capabilities between the Amazon EC2 platform and other software, hardware, virtual, or cloud Traffic Manager variants.

For more complete information about the features available to all product variants, see the Virtual Traffic Manager: User’s Guide.
