A technical overview of Azure Cosmos DB

Azure Cosmos DB is Microsoft’s globally distributed, horizontally partitioned, multi-model database service. The service is designed to allow customers to elastically (and independently) scale throughput and storage across any number of geographical regions. Azure Cosmos DB offers guaranteed low latency at the 99th percentile, 99.99% high availability, predictable throughput, and multiple well-defined consistency models. Azure Cosmos DB is the first and only globally distributed database service in the industry today to offer comprehensive Service Level Agreements (SLAs) encompassing all four dimensions of global distributions which our customers care the most: throughput, latency at the 99th percentile, availability, and consistency. As a cloud service, we have carefully designed and engineered Azure Cosmos DB with multi-tenancy and global distribution in mind. In this blog post, we provide an overview of the notable capabilities and architectural choices of Azure Cosmos DB.

 

The work of Dr. Leslie Lamport, Turing Award Winner and world renowned computer scientist, has profoundly influenced many large scale distributed systems. Azure Cosmos DB is no exception. Over the course of the seven years building Azure Cosmos DB, Leslie’s work has been a constant source of our inspiration for us.
