Cutting AI Agent Costs with Azure Cosmos DB | Farah Abdou | Azure Cosmos DB Conf 2026

Multi-agent AI systems are exploding in 2026 — but they're bleeding money. Farah Abdou, Lead Machine Learning Engineer at SmartServe, reveals how her team rebuilt their entire architecture using Azure Cosmos DB as a unified "Agent Memory Fabric" — combining vector search for semantic caching, Change Feed for event-driven coordination, and optimistic concurrency for conflict prevention. The result: dramatic cost reduction, sub-100ms agent handoffs, and zero state conflicts. 👤 Connect with Farah Abdou 📝 Farah Abdou is a Lead Machine Learning Engineer with a strong focus on AI Research.
