Scalable AI with Azure Cosmos DB: Bringing Generative AI to Enterprise Scale with Super Insight by AVASOFT
Azure Cosmos DB enables scalable AI-driven document processing, addressing one of the biggest barriers to operational scale in today’s enterprise AI landscape. Organizations continue to manage massive volumes of structured and unstructured content—contracts, regulatory filings, operational records, images, and field documentation—yet many workflows remain fragmented, manual, and slow. Every month, the Scalable AI in Action with Azure Cosmos DB series brings the community together with Microsoft partners who are building real, production AI systems — not slides, not demos built for the occasion, but live walkth...
Announcing the Public Preview of Azure Cosmos DB Shell: Open-Source Power Meets AI-Driven Database Automation
 Today, we're thrilled to announce the public preview of Azure Cosmos DB Shell – a powerful, open-source command-line interface that revolutionizes how developers interact with their Azure Cosmos DB databases. With integrated Model Context Protocol (MCP) server support, native agentic capabilities, and bash-like syntax, Azure Cosmos DB Shell transforms database management into an intelligent, developer-friendly experience. From Friction to Flow: Why Cosmos DB Shell, and Why Open Source If you have ever bounced between a portal tab, an SDK sample, and a half-finished script just to answer one database quest...
Introducing langchain-azure-cosmosdb: Build Agentic Apps and RAG with One Database
Build AI Agents and RAG Applications with the New LangChain + LangGraph Connector for Azure Cosmos DB Building AI agents and RAG applications today means stitching together half a dozen services, a vector database, a chat history store, a checkpointer for agent state, a semantic cache, a long-term memory layer. Each adds operational overhead, latency, and technical debt. langchain-azure-cosmosdb collapses that stack. It's a Python LangChain and LangGraph connector that turns Azure Cosmos DB for NoSQL into the single persistence layer for all of your agentic app scenarios. Azure Cosmos DB for NoSQL natively...
Announcing the Private Preview of Cosmos DB Azure RBAC Integration
Introduction Managing access to Azure resources often means dealing with two separate permission models: one for management operations and another for data access. For Azure Cosmos DB customers, this split can increase complexity, slow down onboarding, and create confusion around governance and security boundaries. Today, we’re excited to announce the private preview of Integrated Azure RBAC for Cosmos DB, a major step toward a unified, intuitive permissions experience across Azure. This new capability brings Cosmos DB data plane authorization directly into Azure RBAC, allowing customers to manage both manage...
Azure DocumentDB (with MongoDB compatibility) for Banking: A Modern Customer 360 Approach
Introduction: Transforming Customer Intelligence in Banking Every day, people interact with their bank across mobile apps, branches, call centers, ATMs, chatbots, and partner ecosystems. Each touchpoint holds a piece of the customer story but rarely the whole picture. For many institutions, these moments of truth get lost in a maze of legacy systems, disconnected business units, and data locked away in silos built over decades. Why Customer 360 Matters for Financial Enterprises Banks often distribute customer data across various systems such as core banking, CRM, loan origination, card platforms, digi...
Welcome to Azure Cosmos DB Conf 2026
Today is the day. Azure Cosmos DB Conf 2026, in partnership with AMD, is a free virtual developer event focused on building modern, scalable applications with Azure Cosmos DB. The agenda features Microsoft engineers, product team leaders, and members of the global developer community sharing real-world solutions, deep dives into the database engine, and hands-on patterns for AI-era apps. Whether you build modern web apps, AI agents, multi-cloud platforms, or data-intensive systems on Azure — you’ll find something on the schedule that ships back with you to your codebase. 🎤 Keynote — 9:00 AM PT The ...
7 tips to optimize Azure Cosmos DB costs for AI and agentic workloads
AI apps and agentic workloads expose inefficiencies in your data layer faster than any previous generation of apps. You’re storing embeddings, serving low-latency retrieval, handling bursty traffic from chat and orchestration, and often operating across regions. Done right, Azure Cosmos DB can support these patterns with high performance and cost controls built in. Done wrong, it is easy to over-provision or pay for inefficient queries. Insights from a recently published Azure Cosmos DB cost savings white paper, combined with guidance from Microsoft leader John Savill and real-world feedback from Azure Cosmos ...
General Availability: Dynamic Data Masking for Azure Cosmos DB
Protecting sensitive data is a foundational requirement for modern applications. As organizations scale their use of Azure Cosmos DB across teams, environments, and workloads, controlling who can see sensitive information becomes increasingly important. Today, we are excited to announce the general availability of Dynamic Data Masking (DDM) for Azure Cosmos DB for NoSQL. This capability helps protect sensitive data by automatically masking it for users who do not have permission to view the original values, without requiring changes to application code or data models. Dynamic Data Masking helps teams reduce...
Scalable AI with Azure Cosmos DB: Tredence Intelligent Document Processing (IDP)
Azure Cosmos DB enables scalable AI-driven document processing, addressing one of the biggest barriers to operational scale in today’s enterprise AI landscape. Organizations continue to manage massive volumes of structured and unstructured content—contracts, regulatory filings, operational records, images, and field documentation—yet many workflows remain fragmented, manual, and slow. In this month's edition of our Scalable AI with Azure Cosmos DB series, we featured Tredence and their production-grade Intelligent Document Processing (IDP) solution—an Azure-native architecture designed to transform document-heav...
