What is Azure Cosmos DB?

Editorial review

Cosmos DB is Microsoft's globally distributed database. Deploy across Azure regions, and data replicates automatically with consistency levels you choose. Scale throughput on demand without schema migrations. Multiple APIs-SQL, MongoDB, Cassandra, Gremlin-let you use familiar interfaces. Latency stays low worldwide because data lives close to users. Applications requiring global scale and availability choose Cosmos DB when multi-region complexity shouldn't be the application's problem.
