One of the most celebrated Azure services, CosmosDB is a globally distributed database service. It can access and manage data from scattered data centers while offering tools to scale up your computation resources and global distribution patterns through Microsoft Azure.
Interestingly, CosmosDB ensures 99.99% availability while restricting read and write latencies to single-digit milliseconds. It also supports multiple data models through a single backend – and thus, can be used for graph models, key-value, relational models, and documents. CosmosDB is a top Azure service widely regarded as a NewSQL database, but it stays distinct with its inability to process-relational data models.
