MongoDB Atlas Delivers a Complete Document Database

Don’t build applications with flawed tools. DocumentDB is an incomplete, high-cost, limited mimic of the MongoDB Atlas modern document database.

Choose MongoDB Atlas’s Robust, Global scalability and Developer Empowerment

With full sharding support for horizontal scale-out and clusters that span both global regions and cloud providers, MongoDB Atlas leads the industry in scalability and resiliency to accommodate workloads of any size. Coding of powerful applications is further accelerated through integrated full text search, complete multi-document ACID transactions, and geo-pinning of data. DocumentDB lacks all of this.

Don’t be Hampered by a
Flawed Imitation

DocumentDB fails 63% of all of the correctness tests when comparing the DocumentDB API emulation to MongoDB. In addition, DocumentDB delivers only 2/3rds the performance on transactional workloads. Your developers and application deserve the best. The imitation API is years behind the true MongoDB API and there is no guarantee that it will be improved. DocumentDB is a thin proxy layer implemented on top of a relational database, preventing it from taking advantage of true JSON document capabilities. DocumentDB can only scale to 1 writeable primary node and 15 read replicas and 64TB. MongoDB customers regularly run clusters of tens or hundreds of nodes, with hundreds of terabytes of data.

Build any Class of Application on a Fully Integrated Data Platform

MongoDB Cloud is a foundation for working with data. MongoDB Atlas, Search, and Data Lake serve any class of transactional, operational or analytics workloads through a common API, while Realm Database extends the data foundation to the edge.
