Welcome to Azure Cosmos DB
What is Azure Cosmos DB?
Azure Cosmos DB is a fully managed globally distributed NoSQL database service designed for low latency, high availability, and elastic scalability.
- Multi‑model: Supports document, key‑value, graph, column‑family, and time‑series data.
- Global distribution: Replicate your data to any Azure region with a single click.
- Five consistency levels: Strong, bounded staleness, session, consistent prefix, and eventual.
- Turnkey SLA: Guarantees 99.999% high availability, single-digit millisecond latency, and throughput consistency.
Key Features
- Elastic scalability of throughput and storage.
- Serverless and provisioned throughput models.
- Integrated with Azure Functions, Logic Apps, and Azure Synapse.
- Automatic indexing, no schema required.
- Built‑in security with encryption at rest and in transit.
