Azure Cosmos DB is a fully managed, globally distributed, multi-model NoSQL and relational database service from Microsoft Azure that supports document, key-value, graph, column-family, and vector data models with turnkey global distribution, elastic scale, and SLA-backed latency, throughput, consistency, and availability. The Cosmos DB REST API exposes CRUD and query operations on databases, containers, items, stored procedures, triggers, and user-defined functions using master-key or resource-token authentication, alongside the Cosmos DB Resource Provider (Azure Resource Manager) using Microsoft Entra ID OAuth 2.0.
