MongoDB Atlas, its managed cloud service, operates on AWS, Google Cloud Platform, and Microsoft Azure. Current versions are licensed under the Server Side Public License (SSPL). MongoDB is a member of the MACH Alliance .
The Hierarchical navigable small world (HNSW) algorithm is a graph-based approximate nearest neighbor search technique used in many vector databases. [1] [2] Nearest neighbor search without an index involves computing the distance from the query to each point in the database, which for large datasets is computationally prohibitive.
The company was first established in 2007 as 10gen.

In September 2023, the Realm database was rebranded to be called "Atlas Device SDKs". However, in the following year, September 2024, MongoDB announced the deprecation of the Atlas Device Sync service, synchronizing Realm with MongoDB. The database will stay available as open-source, but will no longer be maintained by the MongoDB team. [14]
A cloud database is a database that typically runs on a cloud computing platform and access to the database is provided as-a-service. There are two common deployment models: users can run databases on the cloud independently, using a virtual machine image, or they can purchase access to a database service, maintained by a cloud database provider.
The desired consistency level is defined at the account level but can be overridden on a per request basis by using a specific HTTP header or the corresponding feature exposed by the SDKs. All five consistency levels have been specified and verified using the TLA+ specification language , with the TLA+ model being open-sourced on GitHub.
However, after mLab was acquired by MongoDB Inc, the game moved to MongoDB Atlas, the global cloud database service. [ 35 ] [ 36 ] Ludo King also utilizes Amazon Web Services (AWS) , and Flentas Technologies, an AWS Partner Network Partner, to "build an internal multiplayer backend system to manage its increasing user traffic more efficiently ...
However, modern NoSQL databases often incorporate advanced features to optimize query performance. For example, MongoDB supports compound indexes and query-optimization strategies, Cassandra offers secondary indexes and materialized views, and Redis employs custom indexing mechanisms tailored to specific use cases.
