# Step 2: Create an application
<a name="getting-started-create-application"></a>

This step describes how to create an application as part of the Refactor Spaces **Getting started** wizard. You can also create an application by choosing **Create application** under **Quick actions** in the Refactor Spaces navigation pane.

Applications are containers of services and routes that provide multi-account traffic routing for services in the application. When you create an application, you must provide Refactor Spaces with a VPC to route traffic from the application to services with private URL endpoints. For each application, Refactor Spaces orchestrate a proxy with an Amazon API Gateway connected to a Network Load Balancer through a VPC link.

**To create an application**

1. On the **Create application** page, enter a name for your application.

1. Under **Proxy VPC**, choose a proxy virtual private cloud (VPC) or choose **Create VPC**.

   An application’s proxy needs a VPC. The proxy’s Network Load Balancer is launched in the VPC and an API Gateway VPC link is configured for the VPC and Network Load Balancer.

   When creating an application in an environment without a network bridge, you need to configure [VPC to VPC connectivity](https://docs.aws.amazon.com/whitepapers/latest/aws-vpc-connectivity-options/amazon-vpc-to-amazon-vpc-connectivity-options.html) between your service VPCs and the Refactor Spaces application proxy VPC.

1. Under **Proxy endpoint type** select **Regional** or **Private**.

   The proxy’s endpoint can be either Regional or private. Regional API Gateway endpoints are accessible through the public internet, and private API Gateway endpoints are only accessible through VPCs.

1. Choose **Next** to move to the **Share environment** page.
