Azure DocumentDB is service of the database of documents NoSQL, it is developed especially for implementation of direct support of JSON and JavaScript in the system of the database.
The solution is suitable for the applications working in a cloud when it is necessary to provide the predicted capacity, the low level of delays and flexible opportunities for work with requests.
Main Characteristics
- Opportunities for work with requests according to a data model of JSON without scheme are provided.
- Transaction accomplishment of logic of JavaScript
- Scalable storage and capacity
- The configured coordination level
- Rapid development using familiar technologies
- The superfast service of the database optimized for record
Azure DocumentDB resources, 2014
The service DobumentDB of the cloud nature also works with the superfast SSD drives having a small delay time and optimized for write operations. High predictable performance and redundant resources provide requirements imposed to capacity. In process of growth of requirements of applications, the storage and capacity can be scaled with a proportional change in value by means of the combined power units. The possibility of setup and selection of optimum level of coordination with accurately certain levels (high, with a limited delay, session and passive) for compliance to scenarios of applications and to requirements to performance is provided that helps to exclude need - to select between two opposite levels — high and passive. Automatic replication of data is executed, it supports the high level of availability.
Access to databases through CRUD, requests and processing of JavaScript in the simple RESTful HTTP interface considerably simplifies process of creation of new applications for business. Programming for DocumentDB is characterized by simplicity, flexibility and availability and does not require writing of the separate code or the JSON or JavaScript expansions. Work quickly with a series of means including packets of SDK for JavaScript, Java, Node.js, Python and .NET.

2015: Microsoft monetizes NoSQL service of the Azure DocumentDB databases
On April 8, 2015 Microsoft announced public service of the Azure DocumentDB NoSQL databases.
Along with it, Microsoft released the data migration tool open source directed to the facilitated transfer of information from other databases in DocumentDB.
About the plans concerning Azure DocumentDB Microsoft announced in August, 2014 and then made available public preview release.
The Azure DocumentDB service is intended for linking of functionality of NoSQL of the database of documents with transaction opportunities of relational databases. DocumentDB service it is native supports the documents JSON and makes available program libraries for a number of languages and platforms, including .NET, Node.js, JavaScript and Python.
Azure DocumentDB uses the technology of indexation without blocking developed by Microsoft Research and used in the engine of processing of online transactions in memory of "Hekaton" in SQL Server 2014. The DocumentDB service also offers the built-in support for other services of data Azure, including HDInsight and Azure Search.
Service is available by three options of purchase (performance levels), and with a possibility of an hourly pay for the standard level of the prices. Options S1, S2, S3 are available at the prices $ $ about $25, 50 and 100 a month.
