# Create EMR Serverless applications from Studio
<a name="create-emr-serverless-application"></a>

Data scientists and data engineers can create EMR Serverless applications directly from the Studio user interface. Before you begin, ensure that you have configured the necessary permissions as described in the [Set up the permissions to enable listing and launching Amazon EMR applications from SageMaker Studio](studio-emr-serverless-permissions.md) section. These permissions grant Studio the ability to create, start, view, access, and terminate the applications.

To create an EMR Serverless application from Studio:

1. In the Studio UI, navigate to the left-side panel and select the **Data** node in the left navigation menu. Then, scroll and choose the **Amazon EMR applications and clusters** option. This opens up a page that displays the Amazon EMR applications that you can access from within the Studio environment, under the **Serverless applications** tab.

1. Choose the **Create serverless application** button at the top right corner. This opens a **Create application** page resembling the view you would see in the [EMR Serverless console](https://console.aws.amazon.com/emrserverless) when choosing to **Use custom settings** in the **application setup options**.

1. Provide the necessary details for your application, including a name and any specific configurable parameters you wish to set, then choose **Create application**.

   All configuration settings have default values and are optional to modify. For detailed information on each available parameter, see [Configuring an application](https://docs.aws.amazon.com/emr/latest/EMR-Serverless-UserGuide/application-capacity.html) in the EMR Serverless user guide.
**Note**  
During the application creation process in the Studio UI, you have the option to either **Create application** or **Create and start application**. Based on your choice, the application will enter either the `Creating` or `Starting` state respectively.  
If you opt to create the application without immediately starting it, make sure the **Automatically start application on job submission** option remains selected. This will ensure that the application automatically transitions to the `Starting` state when you later submit a job to run on it. 
For the simplest setup, we recommend leaving the **Virtual private cloud (VPC)** option set to its default value of **No network connectivity to resources in your VPC** under the **Network connections** section. This allows the application to be created within your domain VPC without requiring any additional networking configuration.  
 In any other case, ensure that you perform the following steps:   
Peer your VPCs.
Add routes to your private subnet route tables.
Configure your security groups as detailed in [Configure network access for your Amazon EMR cluster](studio-notebooks-emr-networking.md).
This ensures the proper networking setup for your application, beyond the default **No network connectivity** option.
For applications created from the Studio Classic UI, the following configuration is automatically applied:  
An enabled Apache Livy endpoint.
The application is tagged with the following:  
sagemaker:user-profile-arn
sagemaker:domain-arn
sagemaker:space-arn
If you create an application outside of Studio, ensure that you manually enable the Apache Livy endpoint and apply the same set of tags to the application.

Once the application is created, the Studio Classic UI displays a *The application has been successfully created* message and the new application appears in the list of **Serverless applications**.
