Azure Cosmos DB

Cosmos DB is Azure's planetary-scale database. It supports multiple APIs: NoSQL (Core/JSON), MongoDB, PostgreSQL, Cassandra, Gremlin (Graph), and Table.

When to Use

• Global Enterprise Applications on Azure: Fully managed NoSQL database with turnkey multi-region replication and single-digit millisecond latency SLAs.
• Multi-Model API Compatibility: Using existing MongoDB, Apache Cassandra, Gremlin (Graph), or PostgreSQL skills via native Cosmos DB APIs.
• Dynamic Scale & Autoscale Request Units (RU/s): Applications with seasonal traffic spikes scaling compute and throughput instantly.
• Guaranteed Consistency Options: Tuning consistency across 5 distinct levels (Strong, Bounded Staleness, Session, Consistent Prefix, Eventual).
