Amazon announces Flexible Cost Allocation on Amazon Transit Gateway
We announce general availability of Flexible Cost Allocation on Amazon Transit Gateway, enhancing how you can distribute Transit Gateway costs across your organization.
Previously, Transit Gateway only used a sender-pay model, where the source attachment account owner was responsible for all data usage related costs. The new Flexible Cost Allocation (FCA) feature provides more versatile cost allocation options through a central metering policy. Using FCA metering policy, you can choose to allocate all of your Transit Gateway data processing and data transfer usage to the source attachment account, the destination attachment account, or the central Transit Gateway account. FCA metering policies can be configured at an attachment-level or individual flow-level granularity. FCA also supports middle-box deployment models enabling you to allocate data processing usage on middle-box appliances such as Amazon Network Firewall to the original source or destination attachment owners. This flexibility allows you to implement multiple cost allocation models on a single Transit Gateway, accommodating various chargeback scenarios within your Amazon Web Services China network infrastructure.
Flexible Cost Allocation is available in both in Amazon Web Services China (Beijing) Region, operated by Sinnet and Amazon Web Services China (Ningxia) Region, operated by NWCD. You can enable this feature using the Amazon Web Services Management Console, Amazon Command Line Interface, and the Amazon Software Development Kit. There is no additional charge for using FCA on Transit Gateway. For more information, see the Transit Gateway documentation pages.
