The talk covers an AI application landing zone with a document ingestion and embedding pipeline using Cosmos DB, Azure Functions, and Microsoft Foundry models, a RAG query flow through Azure API Management and Container Apps, and AKS for bulk re-embedding. It also details reliability patterns (active-active, active-passive, stamp), scalability strategies per layer, observability via Azure Monitor and OpenTelemetry, and security measures including managed identities, private endpoints, retrieval-time access control, and prompt injection defenses. ## Full article daily.dev links to this article rather than hosting it. Read it at the original source: ## Questions this post answers ### How can I design a scalable RAG architecture on Azure using Cosmos DB for vector search? Store documents and their vector embeddings together in Azure Cosmos DB for NoSQL, using its native vector indexing optimized for approximate nearest neighbor search. Azure Functions generate embeddings via Microsoft Foundry models when documents arrive through webhooks, while Container Apps host retrieval APIs that narrow results with vector search then apply metadata and access filters before injecting context into an LLM prompt. _daily.dev surfaces architecture patterns like this for teams designing production RAG pipelines on Azure._ ### What reliability patterns should I use for a multi-region enterprise AI platform on Azure? Three patterns apply: active-active runs two or more regions live simultaneously, active-passive keeps a standby region for failover, and a stamp pattern deploys independent architecture copies that can be provisioned in under an hour. Cosmos DB continuously replicates data to a secondary region to support failover, while Azure Front Door serves as the global entry point with private DNS zones for regional resolution. _engineers weighing failover strategies for AI workloads can track patterns like these via daily.dev._ ### How do you secure a RAG pipeline against prompt injection and unauthorized data access? Enforce access control at retrieval time so users only receive answers grounded in documents they are permitted to see, defend against prompt injection from retrieved content, and apply content safety and PII controls. Infrastructure-level protections include managed identities instead of shared secrets, private endpoints for Cosmos DB and Service Bus, container image signing, trusted registries, and correlated tracing through log analytics with Defender monitoring. _teams hardening RAG systems against prompt injection can follow security practices like these on daily.dev._ ## Similar posts on daily.dev -
