Inside an Enterprise RAG Architecture: How LLMs, Embeddings, and Vector Databases Work Together
Enterprise AI requires more than the capabilities of general-purpose Large Language Models (LLMs). Retrieval-Augmented Generation (RAG) bridges this gap by grounding AI responses in an organization’s trusted data through a pipeline of chunking, embeddings, vector databases, and context-aware retrieval. This overview examines the key challenges organizations must address—including hallucinations, security and access control, data quality, and knowledge freshness—while highlighting the program manager’s critical role in governing, scaling, and evolving RAG from an initial pilot into a secure, reliable, enterprise-grade platform.
