Azure Cosmos DB
Azure Cosmos DB is a globally distributed, multi-model database service provided by Microsoft Azure, designed for building scalable, low-latency applications. It supports multiple data models including document, key-value, graph, and column-family, with automatic indexing and global distribution capabilities. It offers comprehensive service level agreements (SLAs) for throughput, latency, availability, and consistency.
Developers should use Azure Cosmos DB when building globally distributed applications that require low-latency access to data across multiple regions, such as IoT platforms, gaming backends, or e-commerce systems. It is ideal for scenarios needing flexible schema support, horizontal scaling, and multiple consistency models, making it suitable for modern cloud-native applications with high availability requirements.
