Azure Cosmos DB for MongoDB makes it easy to use Azure Cosmos DB as if it were a MongoDB database. You can use your existing MongoDB skills and continue to use your favorite MongoDB drivers, SDKs, and tools by pointing your application to the connection string for your account using the API for MongoDB.
Cosmos DB for MongoDB has numerous benefits compared to other MongoDB service offerings such as MongoDB Atlas:
Instantaneous scalability: With the Autoscale feature, your database scales instantaneously with zero warmup period. Other MongoDB offerings such as MongoDB Atlas can take hours to scale up and up to days to scale down.
Automatic and transparent sharding: The API for MongoDB manages all of the infrastructure for you. This management includes sharding and optimizing the number of shards. Other MongoDB offerings such as MongoDB Atlas, require you to specify and manage sharding to horizontally scale. This automation gives you more time to focus on developing applications for your users.
Five 9's of availability: 99.999% availability is easily configurable to ensure your data is always there for you.
Active-active database: Unlike MongoDB Atlas, Cosmos DB for MongoDB supports active-active across multiple regions. Databases can span multiple regions, with no single point of failure for writes and reads for the same data. MongoDB Atlas global clusters only support active-passive deployments for writes for the same data.
Cost efficient, granular, unlimited scalability: Sharded collections can scale to any size, unlike other MongoDB service offerings. The Azure Cosmos DB platform can scale in increments as small as 1/100th of a VM due to its architecture. This means that you can scale your database to the exact size you need, without paying for unused resources.
Real time analytics (HTAP) at any scale: Run analytics workloads against your transactional MongoDB data in real time with no effect on your database. This analysis is fast and inexpensive, due to the cloud native analytical columnar store being utilized, with no ETL pipelines. Easily create Power BI dashboards, integrate with Azure Machine Learning and Azure Cognitive Services, and bring all of your data from your MongoDB workloads into a single data warehousing solution.

Serverless deployments: Cosmos DB for MongoDB offers a serverless capacity mode. With Serverless, you're only charged per operation, and don't pay for the database when you don't use it.
Free Tier: With Azure Cosmos DB free tier, you get the first 1000 RU/s and 25 GB of storage in your account for free forever, applied at the account level. Free tier accounts are automatically sandboxed so you never pay for usage.
Free 7 day Continuous Backups: Azure Cosmos DB for MongoDB offers free 7 day continuous backups for any amount of data. This means that you can restore your database to any point in time within the last 7 days.
Upgrades take seconds: All API versions are contained within one codebase, making version changes as simple as flipping a switch, with zero downtime.
Role Based Access Control: With Azure Cosmos DB for MongoDB, you can assign granular roles and permissions to users to control access to your data and audit user actions- all using native Azure tooling.
In-depth monitoring capabilities: Cosmos DB for MongoDB integrates natively with Azure Monitor to provide in-depth monitoring capabilities.
Cosmos DB for MongoDB implements the wire protocol for MongoDB. This implementation allows transparent compatibility with MongoDB client SDKs, drivers, and tools. Azure Cosmos DB doesn't host the MongoDB database engine. Any MongoDB client driver compatible with the API version you're using should be able to connect, with no special configuration.
