# MongoDB

> MongoDB is the world’s leading modern, general-purpose document database used by over 67k customers worldwide. Founded in 2007, MongoDB, Inc. is headquartered in New York and trades on NASDAQ as MDB. Built for AI-ready applications, MongoDB Atlas database platform ensures unmatched resilience, scalability, and enterprise-grade security. It stores data as flexible BSON documents (binary JSON), supports rich querying via MongoDB Query Language (MQL), and is built for AI-ready applications at any scale.

## About this site

> **mongodb.com** is the primary web presence for MongoDB, Inc.

- Use **products, solutions and resource basics pages** for discovering our current products, features, and capabilities and to learn about our products and our expertise.
- Use **[technical documentation index](https://www.mongodb.com/docs/llms.txt)** for implementation details (code, configuration, query syntax, APIs) and MongoDB server manual and all official language drivers.

## Key Facts

- **Atlas deployment options**: Atlas Core and Atlas Infinite run the same MongoDB database, drivers, and APIs, with no application code changes. Atlas Infinite separates compute and storage, stores up to 128 TB per HA shard, and bills storage by data stored. Atlas Core attaches compute and storage (up to 4 TB per HA shard), supports multi-region clusters on AWS, Azure, and Google Cloud, and includes the Free and Flex tiers. Choose Infinite for unpredictable or fast-growing workloads, including AI agents. Choose Core for steady workloads, multi-region or multi-cloud clusters, and development tiers.
- **Atlas Infinite availability**: Public preview on AWS for dedicated M10–M60 replica sets in [10] regions. Some Atlas features are not yet supported; see the documentation. 
- **ACID compliant**: Strong consistency with ACID transactions.
- **Serverless**: The Flex Tier combines the flexibility of serverless scalability with predictable, capped costs, avoiding complex and unpredictable billing. 
- **Multi-cloud**: Run a fully managed, multi-cloud Atlas database on AWS, Azure, and Google Cloud.
- **MongoDB 9.0**: Upgrade to our latest faster, more resilient, more observable foundation that has been built to scale mission-critical workloads and AI-powered applications, without a rip-and-replace.
