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...

Azure Cosmos DB at FOSSASIA Summit 2026: Sessions, Conversations, and Community
The FOSSASIA Summit 2026 was an incredible gathering of developers, open-source contributors, startups, and technology enthusiasts from across the region. This year, Azure Cosmos DB and Azure DocumentDB were present at the summit with both technical sessions and a dedicated booth, giving us a great opportunity to connect with the community and talk about building modern applications with cloud-native databases. A Personal Note This was my third time attending FOSSASIA, and it was special in many ways. It was also my first time attending the summit in Bangkok, Thailand, and the venue and overall experience w...
Now Generally Available: Cosmos DB Mirroring in Microsoft Fabric with Private Networks
We’re excited to announce the general availability of private network support for Azure Cosmos DB mirroring in Microsoft Fabric, enabling customers to replicate operational data into Fabric from Azure Cosmos DB accounts secured with private endpoints or virtual networks while continuing to operate within their existing network security models. As more organizations connect operational data with analytics and AI to power new insights and intelligent applications, the ability to do so securely has become increasingly important—making private network support a key capability for bringing operational data into Fabric...
A Look Ahead at Azure Cosmos DB Conf 2026: From AI Agents to Global Scale
Join us for Azure Cosmos DB Conf 2026, a free global, virtual developer event focused on building modern applications with Azure Cosmos DB. This year, Azure Cosmos DB Conf will feature 21 speakers from across the globe, bringing together Microsoft engineers, community leaders, architects, and developers to share how they are building modern applications with Azure Cosmos DB. Attendees will hear directly from experts using Azure Cosmos DB to power real systems—from AI agent memory architectures and retrieval-augmented generation pipelines to globally distributed event-driven micros...
Azure DocumentDB: A Fully Managed MongoDB-Compatible Database
Running MongoDB at scale eventually forces a trade-off: invest heavily in managing your own infrastructure or move to a managed service and risk losing the compatibility and portability your team depends on. Azure DocumentDB is a fully managed, MongoDB-compatible database on Azure, built on an MIT-licensed open-source engine that runs consistently across on-premises, hybrid, and cloud environments. Developers keep the skills and tooling they already have. Infrastructure teams get a pricing model built on compute and storage, with no licensing fees and no throughput unit calculations. Key Capabilities ...
Maximize Azure Cosmos DB Performance with Azure Advisor Recommendations
In the first post of this series, we introduced how Azure Advisor helps Azure Cosmos DB users uncover opportunities to optimize efficiency and make smarter decisions. This follow-up dives deeper into one of the most important categories of guidance: performance. If you've ever dealt with skewed workloads, unexpected RU consumption, or queries that don’t scale as expected, Azure Advisor surfaces exactly the insights you need to diagnose and improve them. In this post, you’ll learn what performance recommendations Advisor provides, why they matter, and how you can use them to enhance the speed, reliability, a...
