About Azure Cosmos DB
By Toolradar Team·
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.

Azure Cosmos DB FAQ
Is Cosmos DB free?
Free tier includes 1000 RU/s and 25GB storage forever. Good for development. Production costs vary based on throughput and storage.
What is Azure Cosmos DB?
Cosmos DB is Microsoft's globally distributed, multi-model database. Document, key-value, graph, and column-family in one service. Single-digit millisecond latency worldwide.
How does Cosmos DB pricing work?
Request Units (RUs) for throughput plus storage. Serverless mode for sporadic workloads. Provisioned for predictable traffic. Can be expensive at scale.
Cosmos DB vs DynamoDB?
Cosmos DB is multi-model with SQL API. DynamoDB is simpler key-value. Cosmos DB has global distribution built-in. DynamoDB cheaper for simple use cases.
What APIs does Cosmos DB support?
SQL (document), MongoDB, Cassandra, Gremlin (graph), and Table. Use familiar APIs with Cosmos DB backend. SQL API is most feature-rich.
