 ## NOTE
 
-This sample showcases how you could deploy a full-stack application with Defang and Django. However, it deploys postgres as a defang service. Defang [services](https://12factor.net/processes) are ephemeral and should not be used to run stateful workloads in production as they will be reset on every deployment. For production use cases you should use a managed database like RDS, Aiven, or others. In the future, Defang will help you provision and connect to managed databases.
