Microsoft announced Cosmos DB integration with Microsoft Fabric at Microsoft Build 2025 on May 19th, expanding the platform's database capabilities to handle semi-structured data for AI training applications. Corporate Vice President Arun Ulagaratchagan revealed Microsoft Fabric now serves more than 21,000 customers, including over 70 percent of the Fortune 500, with more than 50 percent using three or more workloads.
Cosmos DB in Fabric enters preview as part of Fabric Databases expansion, enabling developers to deploy high-performance databases with enterprise-grade dynamic scalability and 99.99% reliability. The integration supports both SQL and NoSQL models, allowing developers to build AI applications grounded in operational, transactional, and analytical data. According to a Bloomberg CIO study referenced by Microsoft, Azure Cosmos DB was the top choice for building generative AI applications, with OpenAI selecting the database to support trillions of transactions and petabytes of data for ChatGPT's 500 million weekly users.
SQL Server 2025 entered public preview with purpose-built AI application support, transforming into a vector database with built-in filtering capabilities, vector search, and flexible interfaces for AI models deployed locally or in the cloud. The release garnered more than 3,400 applicants for private preview, with adoption coming twice as fast as SQL Server 2022.
Digital twin builder launched in preview within Fabric Real-Time Intelligence, providing no-code or low-code capabilities to create, manage, and visualise virtual replicas of physical and logical entities at scale. The tool enables organisations to connect, map, and manage virtual representations of machinery, customers, and dynamic processes for deep analytics and automation.
Microsoft introduced a standalone, full-screen Copilot experience in Power BI for over 30 million monthly active users, enabling natural language conversations with data across multiple reports and semantic models. Fabric data agents integration with Microsoft Copilot Studio allows deployment across Microsoft Teams and Microsoft 365 Copilot for complex dataset reasoning and automated task execution.
