Azure Cosmos DB is designed to store, manage, and query large volumes of both unstructured and structured data. Its NoSQL capabilities and global distribution are leveraged by organizations to support activities like IoT data management, business intelligence, and backend databases for web and mobile applications. While its robust security measures and availability are strengths, there are areas for improvement such as query complexity, integration with services like Databricks and MongoDB, documentation clarity, and performance issues. Enhancements in real-time analytics, API compatibility, cross-container joins, and indexing capabilities are sought after. Cost management, optimization tools, and better support for local development also require attention, as do improvements in user interface and advanced AI integration.
What are the key features of Azure Cosmos DB?Industries use Azure Cosmos DB to support business intelligence and IoT data management, using its capabilities for backend databases in web and mobile applications. The platform's scalability and real-time analytics benefit sectors like finance, healthcare, and retail, where managing diverse datasets efficiently is critical.
Microsoft Azure Cosmos DB was previously known as Microsoft Azure DocumentDB, MS Azure Cosmos DB.

|---|---|---|
| Senior Director of Product Management at a tech vendor with 1,001-5,000 employees | 4.5 | We rebuilt our content management system on Microsoft Azure Cosmos DB, appreciating its ease of use, search efficiency, and reliable uptime. However, vector search costs and limited configuration options need improvement. Our deployment timeframe is significantly shorter than our competitor's. |
| Director, Platform Engineering - Infrastructure Systems and Automation at a computer software company with 1,001-5,000 employees | 4.0 | I use Azure Cosmos DB for compliance data reporting, appreciating its cost efficiency, performance with unstructured data, and scalability, though it lacks native plugins. Setup was easy, and overall, it's worked well for our evolving data needs. |
| Senior Data Engineer at Bajaj Finserv | 3.5 | We use Microsoft Azure Cosmos DB for managing user databases and personalization, benefiting from its partitioning, data retention, and dynamic data masking features. Improvements are needed in security. Switching from Postgres, we've seen a modest cost reduction of 6% to 10%. |
| Solutions Architect at CompuNet | 4.5 | We primarily use Microsoft Azure Cosmos DB to build scalable, cloud-ready solutions. It offers valuable features like global write capability and API flexibility, improving search results and reducing costs, though more customer education on maximizing its benefits is needed. |
| Architecte Cloud at Visiativ SA | 4.0 | We recently implemented Microsoft Azure Cosmos DB as a vector database for AI purposes. It's user-friendly and reliable with global replication, but the RU autoscaling model needs more precision. I previously used MongoDB before switching to Azure Cosmos DB. |
| Associate Data Scientist | 3.5 | I've used Microsoft Azure Cosmos DB for two years to support a high-load chatbot application; it's fast, scalable, and secure, though documentation, live updates, and vector search features could be improved. I’d rate it seven out of ten. |
| Solutions Architect at a retailer with 10,001+ employees | 4.0 | I use Microsoft Azure Cosmos DB primarily for fast data operations in a warehouse setting; its multi-region support, scalability, and auto-scaling reduce our overhead, though continuous backup for multi-region rights could use improvement. |
| Senior Data & Ai Engineer at Cluster Reply | 4.0 | I've used Microsoft Azure Cosmos DB for AI and real-time applications, valuing its speed, scalability, and integration ease, though I'd like more granular access controls; its SDK simplifies deployment and has reduced our operational costs significantly. |
