### Reserved Capacity

The number of idle Stream Machines that will be kept running for your visitors. Defines the number of Stream Machines for each selected region. 

Reserved Capacity selection is only available for the **Balanced** Method.

### Concurrent Capacity

Maximum number of Stream Machines that can be started concurrently. Defines the number of Stream Machines for each selected region. 

### Independent Capacities

When capacities are needed to be configured for each region, both Reserved and Concurrent Capacities can be managed separately.

## Instant Installation :zap:

Instant Installation feature creates a ready-to-use version of your application and entirely eliminates the installation time of your application. Check out the detailed guide in [Connection Optimizations](/streams/guides/connection-optimizations.md#instant-installation)section.&#x20;

When the toggle is first enabled, a blinking grey lightning icon will appear next to the Stream link representing the preparation process, which can take up to 5 minutes. When it's completed it will turn into a permanent green lightning icon to represent it's ready.

## Unreal Engine Pixel Streaming

This toggle will only be visible for Pixel Streaming plugin added Unreal Engine applications. When the toggle is enabled, the system will use [Unreal Engine Pixel Streaming](/streams/unreal-engine-pixel-streaming.md)technology to interactively stream applications.

## Multitenant Pixel Streaming

This toggle will only be visible when the Pixel Streaming toggle is enabled. When it's enabled, the system will create a selected number of virtual tenants inside a Stream Machine, divide the total performance of the host machine into tenants, and serve apps from those tenants. [Multitenant Pixel Streaming](/streams/custom-flows/multi-tenant-streaming.md) feature allows you to serve your app to multiple users from a single Stream Machine.&#x20;

## Unity Render Streaming

As a Unity Verified Solution, Vagon also supports native Unity Render Streaming technology. This toggle will be only visible for Unity Render Streaming plugin added Unity applications. When the toggle is enabled, the system will use [Unity Render Streaming](/streams/unity-render-streaming.md) technology to interactively stream applications.
