Azure App Service allows you to define app settings for each App Service instance. These settings are passed as environment variables to the application code. You can associate a setting with a specific deployment slot, if you want.
For more information, see Configure app settings. In contrast, Azure App Configuration allows you to define settings that can be shared among multiple apps. This includes apps running in App Service, as well as other platforms. Your application code accesses these settings through the configuration providers for.
You can also import and export settings between App Service and App Configuration. This capability allows you to quickly set up a new App Configuration store based on existing App Service settings. You can also share configuration with an existing app that relies on App Service settings. There's a limit of 10 KB for a single key-value, including attributes such as label, content-type, tags, and other metadata.
This limit should be sufficient for a single setting in most applications. If you find that your setting is larger than this limit, you may consider storing your data elsewhere and add a reference of that data in App Configuration.
You control who can access App Configuration at a per-store level. Use a separate store for each environment that requires different permissions. This approach provides the best security isolation. If you do not need security isolation between environments, you can use labels to differentiate between configuration values.
Use labels to enable different configurations for different environments provides a complete example. If you created a store prior to the introduction of the Standard tier, it automatically moved to the Free tier upon general availability. You can choose to upgrade to the Standard tier or remain on the Free tier. You can't downgrade a store from the Standard tier to the Free tier. You can create a new store in the Free tier and then import configuration data into that store.
Both App Configuration tiers offer core functionality, including config settings, feature flags, Key Vault references, basic management operations, metrics, and logs.
Resources per subscription : A resource consists of a single configuration store. Then unnecessary checks for changes could be avoided. The new refresh mechanism allows users to keep their configuration updated using a middleware to determine activity. As long as the ASP. NET Core web application continues to receive requests, the configuration settings continue to get updated with the configuration store. The application can be configured to trigger refresh for each request by adding the Azure App Configuration middleware from package Microsoft.
At the time of initialization of the configuration provider, the user can use the ConfigureRefresh method to register the configuration settings to be updated with an optional cache expiration time. In case the cache expiration time is not specified, a default value of 30 seconds is used. In order to keep the settings updated and avoid unnecessary calls to the configuration store, an internal cache is used for each setting.
Until the cached value of a setting has expired, the refresh operation does not update the value. This happens even when the value has changed in the configuration store. For more information about Azure App Configuration, check out the following resources. You can find step-by-step tutorials that would help you get started with dynamic configuration using the new refresh mechanism within minutes.
