As a globally distributed, multi-model database service, Azure Cosmos DB offers turnkey global distribution across any number of Azure's vetted and monitored datacenters. It offers a comprehensive set of APIs for any application using it and is the only cloud database service that supports transparent horizontal scaling with consistent millisecond performance guarantees.
It is a fully-managed cloud service built for the cloud. It's built for globally distributed applications and provides a highly-scalable low-latency store. Its multi-model database is capable of handling any volume of data, offering single-digit-millisecond latencies at the 99th percentile, guarantees five-nines of availability, maintains strong consistency, and provides comprehensive service level agreements (SLAs).
