Benefits

MongoDB is a MongoDB-compatible database service that is developed based on the Apsara system and a high-reliability storage engine. MongoDB uses a multi-node architecture to ensure high availability, and supports elastic scaling, disaster recovery, backup and restoration, and performance optimization.

Flexible deployment architectures
MongoDB supports multiple deployment architectures to meet the requirements of different business scenarios.

Elastic scaling
MongoDB allows you to change instance configurations to adapt to shifting business needs. You can change the configurations of an instance (instance specifications, storage capacity, and number of nodes) based on your business needs. You can also specify that the new configurations take effect during off-peak hours to avoid possible impacts on your business.

Compatibility with DynamoDB
MongoDB is fully compatible with the MongoDB protocol. Sharded cluster instances of MongoDB 4.0 are highly compatible with the DynamoDB protocol. You can directly create DynamoDB-compatible sharded cluster instances in the console.
