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.

Is Azure Cosmos DB worth the price?

85/100

Azure Cosmos DB offers a generous Free Tier, making it accessible for initial development.

The Serverless option at $0.25 per 1M RUs is competitive for intermittent workloads, while the Provisioned tier at $0.008 per 100 RU/s/hour provides cost-effective reserved capacity. This pricing model is fair and flexible, catering to a wide range of use cases from small projects to large-scale production.

How Azure Cosmos DB Compares to Competitors

Compared to AWS DynamoDB, Cosmos DB's Serverless model at $0.25 per 1M RUs is competitive, with DynamoDB's on-demand pricing around $1.25 per million write request units and $0.25 per million read request units. For provisioned throughput, both offer similar cost structures, but Cosmos DB's multi-model support can offer better value than managing separate databases like MongoDB Atlas which has its own pricing per cluster size.
