Azure Germany is available to customers and partners in the European Union (EU) and European Free Trade Association (EFTA) and provides data residency in Germany with additional levels of control and data protection with a modest price uplift over global cloud offerings (% varies per service).
DocumentDB is not available in the UK West region. Please select another region.

At any scale, you can store data and provision throughput capacity. Each collection is billed hourly based on the amount of data stored (in GBs) and throughput reserved in units of 100 RUs/second.
|SSD Storage (per GB)||$0.25 per GB/month|
|Reserved RUs/second (per 100 RUs)||$0.008/hr (~$5.952/month)|
For high-throughput and high-storage workloads, you can create partitioned collections by defining a partition key at collection creation. A partitioned collection will seamlessly scale out as the quantity of stored data grows and reserved throughput increases.
DocumentDB Emulator (Free)
Download the free DocumentDB Emulator to develop and test applications using DocumentDB from your local machine. Once you’re satisfied with how your application works, you can deploy it by just changing your configuration to point to an Azure DocumentDB instance.
Planet scale with geo-replication
DocumentDB collections can be globally distributed to help you easily build apps with planet scale, which means that all your data is automatically replicated to the regions you specify. Your app continues to work with one logical endpoint, while your data is automatically served from the region closest to your users with an intuitive programming model for data consistency and 99.99 availability. Globally distributed collections are billed based on the storage consumed in each region and throughput reserved for each DocumentDB collection x the number of regions associated with a DocumentDB database account. Standard data transfer rates apply for replication data transfer between regions. As an example, say you have a database account spanning three Azure regions and two collections provisioned with 1 million RUs and 2 million RUs respectively. The total RUs provisioned for the first collection will be 3 million RUs (1 million RUs x 3 regions) and the second one will be 6 million RUs (2 million RUs x 3 regions).
High throughput and low-latency queries
With DocumentDB, you can write a sustained volume of data, and it will be synchronously indexed to serve consistent SQL queries using a write-optimised, latch-free database engine designed for solid-state drives (SSDs) and low-latency access. Read and write requests are always served from your local region, while data is distributed globally. You can further optimise performance by customising automatic index behaviour.
Collections with pre-defined performance and size
DocumentDB also offers collections with pre-defined 10 GB storage and throughput quantities – S1 (250 RU/s billed at $0.0336/hr), S2 (1000 RU/s billed at $0.0672/hr) or S3 (2500 RU/s billed at $0.1344/hr). If you want to reconfigure throughput for these collections, see Changing performance levels using the Azure Portal. If you want to take advantage of partitioned collections, you need to convert your previously created S1, S2 or S3 collections to use the limitless throughput and storage scale described above, as described in Partitioning and scaling in Azure DocumentDB.
Support and SLA
- We provide technical support for all Azure services released for General Availability, including Document DB, through Azure Support, starting at $29.0/month. Billing and subscription management support is provided at no cost.
- SLA: We guarantee that at least 99.99% of the time we will successfully process requests to perform operations against DocumentDB Resources. To learn more about our SLA, please visit the SLA page.
- What is a Request Unit?
A Request Unit (RU) is the measure of throughput in DocumentDB. 1 RU corresponds to the throughput of the GET of a 1 KB document. Every operation in DocumentDB, including reads, writes, SQL queries and stored procedure executions, has a deterministic Request Unit value based on the throughput required to complete the operation. Instead of thinking about CPU, IO and memory, and how they each affect your application throughput, you can think in terms of a single Request Unit measure.

- How does Request Unit usage appear on my bill?
You are billed hourly for each collection created within a DocumentDB account. Each collection is billed at a flat, predictable hourly rate based on the number of Request Units that have been provisioned during that hourly period.
- If I specify my own performance for a collection how is storage billed?
Storage capacity is billed in units of the maximum hourly amount of data stored, in GB, over a monthly period. For example, if you utilised 100 GB of storage for half of the month and 50 GB for the second half of the month, you would be billed for an equivalent of 75 GB of storage during that month.
- What if my collection is active for less than an hour?
You are billed the flat rate for each hour that the collection exists, regardless of usage or if the collection is active for less than an hour. For example, if you create a collection and delete it 5 minutes later, your bill will reflect a charge for 1 unit hour.
- When does the billing rate change after I upgrade a collection?
If you define your own performance for a collection and you upgrade at 9:30 a.m. from 400 RUs to 1,000 RUs and downgrade at 10:45 a.m. back to 400 RUs, you will be charged for two hours of 1,000 RUs.
If you select a pre-defined collection performance level and you upgrade at 9:30 a.m. from an S1 collection to an S3 collection, and downgrade at 10:45 a.m. back to S1, you will be charged for two hours of S3.
- How do I scale throughput per collection up or down?
You can scale the number of Request Units for each collection up or down within your DocumentDB account by using the Azure Portal, one of the supported SDKs or the REST API.
- Can I purchase a mix of collections with pre-defined and user-defined performance with a single database account?
Yes, you can have a mix of collections. However, for new applications, you are encouraged to create collections with user-defined performance as they can support large storage sizes and provisioned throughput, as well as a flexible and granular billing model.
- Can I move from a pre-defined performance collection to a collection with user-defined performance?
Yes, this is possible and encouraged.
To move a collection of S1, S2 or S3 performance tier to the user-defined performance tier with the same storage size, see Changing performance levels using the Azure Portal.
To move an existing single collection to a partitioned collection, see Partitioning and Scaling in Azure DocumentDB.
