ApsaraDB for MongoDB supports standalone, replica set, and sharded cluster deployment architectures and provides enterprise-class capabilities such as security audit and point-in-time backup. These features have been widely used in the Internet, IoT, gaming, and finance industries.

Read/write splitting

ApsaraDB for MongoDB uses the architecture of three-node replica sets to guarantee high availability. Three data nodes are located on different physical servers and automatically synchronize data. The primary and secondary nodes are configured with different endpoints. MongoDB drivers allocate read/write requests to them. For more information about the architecture, see Architecture of ApsaraDB for MongoDB.

Flexible business scenarios

ApsaraDB for MongoDB has no schema and is suitable for startup business needs. You do not need to worry about changing schemas. You can store structured data in ApsaraDB RDS, flexible business data in ApsaraDB for MongoDB, and hot data in ApsaraDB for Redis or ApsaraDB for Memcache. This helps you write and read business data with high efficiency and reduce the cost of data storage.


ApsaraDB for MongoDB supports two-dimensional spatial indexes. Therefore, ApsaraDB for MongoDB can provide support for location-based apps. Its dynamic storage mode is also suitable for storing heterogeneous data from multiple systems. This satisfies the requirements of apps.

IoT scenarios

ApsaraDB for MongoDB has features such as high performance and asynchronous data writing. It can achieve the processing capability of an in-memory database in specific scenarios.
