## `APIRouter`

Nehmen wir an, die Datei, die nur für die Verwaltung von Benutzern zuständig ist, ist das Submodul unter `/app/routers/users.py`.

Sie möchten die *Pfadoperationen* für Ihre Benutzer vom Rest des Codes trennen, um ihn organisiert zu halten.

Aber es ist immer noch Teil derselben **FastAPI**-Anwendung/Web-API (es ist Teil desselben „Python-Packages“).

### Provider-specific Notes

#### Various

   Core changes:

  * Support for load balancers with source ranges

#### AWS

Core changes:

  * Support for ELBs with complex configurations: better subnet selection with
multiple subnets, and internal ELBs
  * Support for VPCs with private dns names
  * Multiple fixes to EBS volume mounting code for robustness, and to support

And after searching for a long time for a similar framework and testing many different alternatives, APIStar was the best option available.

Then APIStar stopped to exist as a server and Starlette was created, and was a new better foundation for such a system. That was the final inspiration to build **FastAPI**.
