 # Azure Cosmos DB FAQ
 ## Azure Cosmos DB fundamentals
-### What is Azure Cosmos DB?
-Azure Cosmos DB is a globally replicated, multi-model database service that offers rich querying over schema-free data, helps deliver configurable and reliable performance, and enables rapid development. It's all achieved through a managed platform that's backed by the power and reach of Microsoft Azure. 
-
-Azure Cosmos DB is the right solution for web, mobile, gaming, and IoT applications when predictable throughput, high availability, low latency, and a schema-free data model are key requirements. It delivers schema flexibility and rich indexing, and it includes multi-document transactional support with integrated JavaScript.

-For more database questions, answers, and instructions for deploying and using this service, see the [Azure Cosmos DB documentation page](https://docs.microsoft.com/azure/cosmos-db/).

 First you must sign up for an Azure subscription. Once you sign up for an Azure subscription, you can add a SQL API container to your Azure subscription.

 ### What is the Azure Cosmos DB API for MongoDB?
 The Azure Cosmos DB API for MongoDB is a compatibility layer that allows applications to easily and transparently communicate with the native Azure Cosmos DB database engine by using existing, community-supported Apache MongoDB APIs and drivers. Developers can now use existing MongoDB tool chains and skills to build applications that take advantage of Azure Cosmos DB. Developers benefit from the unique capabilities of Azure Cosmos DB, which include auto-indexing, backup maintenance, financially backed service level agreements (SLAs), and so on.

 ### Why do I get throttled when I try to create lot of tables one after another in the Table API?
 Azure Cosmos DB is an SLA-based system that provides latency, throughput, availability, and consistency guarantees. Because it is a provisioned system, it reserves resources to guarantee these requirements. The rapid rate of creation of tables is detected and throttled. We recommend that you look at the rate of creation of tables and lower it to less than 5 per minute. Remember that the Table API is a provisioned system. The moment you provision it, you will begin to pay for it.
