When you create an Azure Function, there needs to be an Azure Storage Account behind it, for various runtime needs (https://learn.microsoft.com/en-us/azure/azure-functions/functions-app-settings#azurewebjobsstorage).

For local development, you can choose to either use a real Azure Storage Account in the cloud by setting AzureWebJobsStorage app setting to that storage account's connection string, or you can use a local emulator (Azurite) that simulates a Storage Account on your machine.

So if you select that Azurite box, it will set AzureWebJobsStorage to use your local emulator instead, therefore no need for a storage account in the cloud.
