Microsoft has announced several improvements to the Azure DocumentDB service that allow it to act as a globally distributed NoSQL database.
Today we are pleased to introduce global databases for Azure DocumentDB. Global databases allow you to replicate data across multiple Azure regions to achieve low latency access with well-defined data consistency while offering clear availability SLAs. Global databases are designed to meet the needs of planet scale applications such as IoT systems serving globally distributed devices or internet scale web applications that deliver highly personalized experiences.
In addition to the addition of globally distributed databases, Microsoft is also providing a layer to enable support for MongoDB database drivers. If you have an application that uses MongoDB today, you can move the database to Azure DocumentDB and your existing MongoDB drivers will work but with some added benefits that are provided by Azure DocumentDB.
These new features are currently in preview only.
