Enterprise RAG (Retrieval-Augmented Generation) architecture built with Spring AI on Azure App Service integrates Azure OpenAI Service for LLM inference and embeddings. The RAG Pipeline Component orchestrates document retrieval from Azure Storage Account, vector search via Azure Database for PostgreSQL with PGVector extension, and function calling through Azure SQL Database. Application Insights monitors performance while Key Vault secures API keys and connection strings, demonstrating production-ready AI application patterns for Spring developers.
