 For example, for an app created on [www.luis.ai](https://www.luis.ai), if you create a LUIS resource in two regions, **westus** and **eastus**, and add these to the app as resources, the app is published in both regions. For more information about LUIS regions, see [Regions](luis-reference-regions.md).
