 * A user account that's a member of the *Azure AD DC administrators* group in your Azure AD tenant.

+> As there's [no access to domain controllers in Azure AD DS](faqs.md#can-i-connect-to-the-domain-controller-for-my-managed-domain-using-remote-desktop), you can't create and use a Central Store for group policy administrative templates in a managed domain. [Sysvol isn't included in on-premises Azure AD Connect synchronization](synchronization.md#what-isnt-synchronized-to-azure-ad-ds), so you also can't create an on-premises Central Store and synchronize it to Azure AD DS through Azure AD.

 ## Install Group Policy Management tools
 
 To create and configure Group Policy Object (GPOs), you need to install the Group Policy Management tools. These tools can be installed as a feature in Windows Server. For more information on how to install the administrative tools on a Windows client, see install [Remote Server Administration Tools (RSAT)][install-rsat].

-## Async
 
-We recommend that you write your Azure Function as an asynchronous coroutine using the `async def` statement.
+## Concurrency
 
-```python
-# Will be run with asyncio directly
+By default, the Functions Python runtime can only process one invocation of a function at a time. This concurrency level might not be sufficient under one or more of the following conditions:
+
++ You're trying to handle a number of invocations being made at the same time.
++ You're processing a large number of I/O events.
++ Your application is I/O bound.
+
+In these situations, you can improve performance by running asynchronously and by using multiple language worker processes.  
 
+### Async
+
+We recommend that you use the `async def` statement to make your function run as an asynchronous coroutine.
+
+```python
+# Runs with asyncio directly
 
 async def main():
     await some_nonblocking_socket_io_op()
 ```
 
-If the main() function is synchronous (no  qualifier), we automatically run the function in an `asyncio` thread-pool.
+When the `main()` function is synchronous (without the `async` qualifier), the function is automatically run in an `asyncio` thread-pool.
 
 ```python
-# Would be run in an asyncio thread-pool
-
+# Runs in an asyncio thread-pool
 
 def main():
     some_blocking_socket_io()
 ```
 
+### Use multiple language worker processes
+
+By default, every Functions host instance has a single language worker process. However there's support to have multiple language worker processes per host instance. Function invocations can then be evenly distributed among these language worker processes. Use the [FUNCTIONS_WORKER_PROCESS_COUNT](functions-app-settings.md#functions_worker_process_count) application setting to change this value. 
+
 ## Context
 
 To get the invocation context of a function during execution, include the [`context`](/python/api/azure-functions/azure.functions.context?view=azure-python) argument in its signature.
