Choose MongoDB Atlas’s Seamless Developer Experience
Cosmos DB requires five separate and incompatible APIs to deliver the functionality offered by MongoDB Atlas. You may as well run five separate databases. With its powerful query language and aggregation pipeline, distributed multi-document ACID transactions, schema governance, client-side field level encryption, queryable encryption and more, you can build, scale, and secure applications faster, with lower effort on MongoDB Atlas.
Deploy Where its Best for
Your Applications
Cosmos DB only can be deployed on Microsoft’s cloud. MongoDB Atlas runs on AWS, Microsoft Azure, and Google Cloud, and with multi-cloud clusters, a single cluster runs across all three platforms. In addition, MongoDB can be deployed on infrastructure you manage yourself - giving you complete freedom to run anywhere.
Work With a Modern Database Platform
MongoDB Cloud is a foundation for working with data. MongoDB Atlas, Search, and Data Federation serve any class of transactional, operational or analytics workloads through a common API, while Atlas App Services and Atlas for the Edge extend the data foundation to the edge.
