Azure Cosmos DB

Definition

Azure Cosmos DB is a globally distributed, multi-model database service designed to provide low-latency access to data across multiple regions. It supports various data models like document, key-value, graph, and column-family, making it versatile for handling diverse applications. With its scalability and availability, it plays a crucial role in big data processing and enables serverless application design patterns by allowing developers to build applications that can scale seamlessly without managing the underlying infrastructure.

5 Must Know Facts For Your Next Test

1. Azure Cosmos DB offers five consistency models: strong, bounded staleness, session, eventual, and consistent prefix, allowing developers to choose the right trade-off between performance and consistency.
2. It automatically scales throughput and storage based on application needs, ensuring efficient resource usage without manual intervention.
3. With built-in support for APIs like SQL, MongoDB, Cassandra, Gremlin, and Table storage, Azure Cosmos DB allows easy integration with existing applications and services.
4. The service provides 99.999% availability SLA when configured for multi-region distribution, ensuring applications remain operational even in the event of failures.
5. Azure Cosmos DB supports serverless architecture by allowing developers to execute operations without managing servers directly, optimizing costs and simplifying deployment.
