Cosmos DB is a distributed database engine with a core set of features, like.
- Ability to distribute your database globally
- Ability to scale both storage and throughput
- Low latency with enterprise grade security features
Cosmos DB can reshape data into formats that you may already be using. You can create a data model and then expose your model using one of many Cosmos DB API's.
For more information, see Azure Cosmos DB.
