 # Edit host and app settings for logic apps in single-tenant Azure Logic Apps
 
-In *single-tenant* Azure Logic Apps, the *app settings* for a logic app specify the global configuration options that affect *all the workflows* in that logic app. However, these settings apply *only* when these workflows run in your *local development environment*. While running locally, the workflows can access these app settings as *local environment variables*, which are used by local development tools for values that can often change between environments. For example, these values can contain connection strings. When you deploy to Azure, app settings are ignored and aren't included with your deployment.

 Your logic app also has *host settings*, which specify the runtime configuration settings and values that apply to *all the workflows* in that logic app, for example, default values for throughput, capacity, data size, and so on, *whether they run locally or in Azure*.
