One Codebase, Any Cloud: Retail DB with OSS & Azure | Khelan Modi | Azure Cosmos DB Conf 2026

Retail engineering teams face a choice that shouldn't be a choice: run your database on-premises for compliance and cost control, or move to the cloud for scale and managed operations. With DocumentDB and Azure DocumentDB, that's a false dilemma. Khelan Modi (Program Manager, Azure Cosmos DB) walks through a complete retail store database — product catalog, inventory, orders, and vector-powered recommendations — built once using MongoDB-compatible APIs and deployed both on-prem via the DocumentDB Kubernetes operator and on Azure as a fully managed service. Same drivers. Same queries. Zero application changes. You'll walk away with an architecture you can replicate and an honest accounting of the tradeoffs at each layer. 👤 Connect with Khelan Modi 📝 Khelan Modi, a dynamic Product Manager at the forefront of the Azure Cosmos DB team, seamlessly integrates his deep expertise in databases with a passion for AI innovation.
