Azure Cosmos DB Documentation
Welcome to the official Microsoft documentation for Azure Cosmos DB. This comprehensive resource provides in-depth information, tutorials, API references, and best practices to help you leverage the power of Azure Cosmos DB for your mission-critical applications.
What is Azure Cosmos DB?
Azure Cosmos DB is a globally distributed, multi-model database service that enables you to rapidly develop and scale your applications with predictable latency and high availability. It offers multiple data models, including document, key-value, graph, and column-family, and supports various APIs like SQL (Core), MongoDB, Cassandra, Gremlin, and Table.
Key Features
- Global Distribution: Replicate your data across any number of Azure regions with active-active capabilities.
- Elastic Scalability: Scale throughput and storage independently and elastically, on demand.
- Guaranteed High Availability: Achieve 99.999% availability for applications requiring near-constant uptime.
- Multi-Model and Multi-API: Supports various data models and popular APIs, making migration and development flexible.
- Tunable Consistency: Choose from five well-defined consistency levels to balance performance and consistency needs.
- Serverless and Autoscale: Optimize costs and manage resources efficiently with serverless options and autoscale capabilities.
