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 The post Azure DocumentDB: A Fully Managed MongoDB-Compatible Database appeared first on Azure Cosmos DB Blog.

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 The post Maximize Azure Cosmos DB Performance with Azure Advisor Recommendations appeared first on Azure Cosmos DB Blog.

The Vercel AI SDK is an open-source TypeScript toolkit that provides the core building blocks for integrating AI into any JavaScript application. It works with 20+ AI providers out of the box—including OpenAI, Azure OpenAI, Anthropic, Google, Mistral, and more—so you can write your code once and switch providers by changing a single import.

Strengthen Identity Security and Eliminate Account Keys Identity is becoming the new security perimeter. As organizations modernize their cloud applications, long‑lived secrets and shared keys introduce unnecessary risk. Azure Cosmos DB now fully supports Microsoft Entra ID for both control plane and data plane access, giving customers a secure, passwordless, least‑privilege alternative to legacy key‑based The post How to Enable Microsoft Entra ID for Azure Cosmos DB (NoSQL) appeared first on Azure Cosmos DB Blog.

Series: Building Serverless Applications with Azure Functions and Azure Cosmos DB In the first post of this series, we focused on establishing the fundamentals of serverless architecture by building and deploying a simple HTTP API using Azure Functions and FastAPI. The post centred on serverless compute, showing how Azure Functions handles execution, scaling, and infrastructure The post Part 2: Building a Python CRUD API with Azure Functions and Azure Cosmos DB appeared first on Azure Cosmos DB Blog.

If you spend time in the Azure Portal’s using Azure Cosmos DB Data Explorer, you know it’s a “lots of screens, lots of tabs, lots of work happening” kind of place. So I’m excited to share a small upgrade that makes a big difference: Dark Mode is now supported in Cosmos DB Data Explorer.
