+## Production Deployment on Azure Applciation Landing Zones
+
+This sample is designed to get you started quickly and let you experiment with Java intelligent Apps RAG architectures on Azure.For production deployment, you can use the [Azure Application Landing Zones (LZA)](https://learn.microsoft.com/en-us/azure/cloud-adoption-framework/scenarios/app-platform/ready) to deploy the solution maintaining best practices for security, monitoring, networking and operational excellence.
+
+Check the [chat-with-your-data-lza-app-accelerator](https://github.com/dantelmomsft/chat-with-your-data-java-lza-app-accelerator) to see how you can deploy this solution on App Service LZA or Azure Container Apps LZA.
