 Azure Cosmos DB free tier makes it easy to get started, develop, test your applications, or even run small production workloads for free. When free tier is enabled on an account, you'll get the first 1000 RU/s and 25 GB of storage in the account for free. The throughput and storage consumed beyond these limits are billed at regular price. Free tier is available for all API accounts with provisioned throughput, autoscale throughput, single, or multiple write regions.
 
-Free tier lasts indefinitely for the lifetime of the account and it comes with all the [benefits and features](introduction.md#key-benefits) of a regular Azure Cosmos DB account. These benefits include unlimited storage and throughput (RU/s), SLAs, high availability, turnkey global distribution in all Azure regions, and more.

 You can have up to one free tier Azure Cosmos DB account per an Azure subscription and you must opt in when creating the account. If you don't see the option to apply the free tier discount, another account in the subscription has already been enabled with free tier. If you create an account with free tier and then delete it, you can apply free tier for a new account. When creating a new account, it’s recommended to enable the free tier discount if it’s available.

 Today's applications are required to be highly responsive and always online. They must respond in real time to large changes in usage at peak hours, store ever increasing volumes of data, and make this data available to users in milliseconds. To achieve low latency and high availability, instances of these applications need to be deployed in datacenters that are close to their users.
 
-Recently, the surge of AI-powered applications created another layer of complexity, because many of these applications currently integrate a multitude of data stores. For example, some teams built applications that simultaneously connect to MongoDB, Postgres, Redis, and Gremlin. These databases differ in implementation workflow and operational performances, posing extra complexity for scaling applications.

-## Azure Cosmos DB is more than an AI database
-
-Besides AI database, Azure Cosmos DB should also be your goto database for web, mobile, gaming, and IoT applications. Azure Cosmos DB is well positioned for solutions that handle massive amounts of data, reads, and writes at a global scale with near-real response times. Azure Cosmos DB's guaranteed high availability, high throughput, low latency, and tunable consistency are huge advantages when building these types of applications. Learn about how Azure Cosmos DB can be used to build IoT and telematics, retail and marketing, gaming and web and mobile applications.
