Specific characteristics

Azure Cosmos DB is Microsoft’s globally-distributed, horizontally scalable, multi-model database service. Our mission with Azure Cosmos DB is to enable you to write highly scalable, globally distributed apps, easily. With its turnkey support for global distribution, Azure Cosmos DB seamlessly makes your data available close to where your users are, anywhere around the world; it offers guaranteed low latency, well-defined consistency and high availability around the globe. Azure Cosmos DB allows you to elastically scale throughput and storage anywhere in the world, based on your needs, and offers a multitude of well-defined consistency models, data models and APIs – so you can select the right ones for your app.

Azure Cosmos DB started in late 2010 to address developer pain-points that are faced by large scale applications inside Microsoft. Since building globally distributed applications is not a problem unique to just to Microsoft, we made the service available externally to all Azure Developers in the form of Azure DocumentDB. Azure Cosmos DB is the next big leap in the evolution of DocumentDB and we are now making it available for you to use. As a part of this release of Azure Cosmos DB, DocumentDB customers (with their data) are automatically Azure Cosmos DB customers. The transition is seamless and they now have access to a broader range of new capabilities offered by Azure Cosmos DB.

Azure Cosmos DB started as “Project Florence” in the late 2010, which eventually grew into DocumentDB before finally blossoming into the Cosmos DB as you now know it.

Competitive advantages

Global distribution
Easily build globally-distributed applications without the hassle of complex, multiple-datacenter configurations. Designed as a globally distributed database system, Cosmos DB automatically replicates all of your data to any number of regions of your choice, for last, responsive access. Cosmos DB supports transparent multi-homing and guarantees 99.99% high availability.

Elastic scaleout of storage and throughput
With Cosmos DB, you only pay for the throughput and storage you need. Cosmos DB allows you independently and elastically scale storage and throughput across one or multiple global regions.

Guaranteed single-digit-ms latency
Serve read and write requests from the nearest region while simultaneously distributing data across the globe. With its latch-free and write optimized database engine, Cosmos DB guarantees less than 10-ms latencies on reads and less than 15-ms latencies on (indexed) writes at the 99th percentile.

Choice of consistency
Cosmos DB offers five well-defined consistency levels—strong, bounded staleness, consistent-prefix, session, and eventual—for an intuitive programming model with low latency and high availability for applications spanning the world.

Multi-model + multi-API
Only Cosmos DB allows you to use key-value, graph, and document data in one service, at global scale and without worrying about schema or index management. Cosmos DB automatically indexes all data, and allows you to use your favorite NoSQL API including SQL, JavaScript, Gremlin, MongoDB, and Azure Table Storage to query your data.

Enterprise-level SLAs
Rest assured your apps are running on world-class infrastructure, with “battle-tested” service, in the most trusted cloud. Cosmos DB is the first and only service to offer industry-leading 99.99% SLAs for latency at the 99th percentile, guaranteed throughput, consistency and high availability.

Typical application scenarios

Azure Cosmos DB enables writing globally distributed applications and allows you to get going and deliver quickly.

Mobile (Real Madrid, Orange Tribes)
Mobile apps need to support different versions and different platforms, each often using a slightly different schema. Cosmos DB’s automatic indexing capabilities allow you to easily change schemas on the fly without having to make any database changes.

Web/Global Marketing (MSN, Telenor)
Web-scale apps need to be able to grow and shrink based on demand. Cosmos DB supports scaling up and down to handle any size workload.

Gaming (Next Games)
Gaming apps need to be able to grow and shrink based on demand. Cosmos DB supports scaling up and down to handle any size workload.

IoT and Analytics (LG CNS)
With Cosmos DB, you can easily store and query device registration data for your IoT application. With connectivity to Hadoop on Azure, Cosmos DB can play a key role in your intelligent, data-driven applications.

Retail and e-commerce (Jet.com, Asos, Domino’s Pizza)
Support in-depth queries over diverse product catalogs, traffic spikes, and rapidly changing inventory.

Key customers

Market metrics

Gartner Research positions Microsoft as the leader in the Magic Quadrant Operational Database Management Systems in 2016.

Licensing and pricing models

With Azure Cosmos DB, pay only for the storage you use and the throughput you provision globally. Throughput can be scaled up or down depending on the needs of your application as low as a few 100 requests per second to millions of requests per second across any number of Azure regions.
