Building Production-Ready RAG Applications: A Practical Guide

Retrieval-Augmented Generation (RAG) has become the de facto architecture for grounding large language models (LLMs) in external knowledge. While building a basic RAG prototype is straightforward—connect a vector store to an LLM and query—shifting that system to production introduces a host of engineering challenges: latency, cost, reliability, retrieval accuracy, and security. This guide walks through the essential considerations and trade-offs for deploying RAG at scale.

1. Data Indexing: The Foundation

The quality of your RAG system is bounded by the quality of your indexed data. Production indexing requires careful attention to document processing, chunking, and embedding.
