# Bundles and images for WorkSpaces Pools
<a name="pools-images"></a>

A *WorkSpace bundle* is a combination of an operating system, and storage, compute, and software resources. When you launch a WorkSpace, you select the bundle that meets your needs. The default bundles available for WorkSpaces are called *public bundles*. For more information about the various public bundles available for WorkSpaces, see [Amazon WorkSpaces Bundles](https://aws.amazon.com/workspaces/details/#Amazon_WorkSpaces_Bundles).

If you've launched a Windows WorkSpace and have customized it, you can create a custom image from that WorkSpace for use with WorkSpaces Pool. Linux are not supported in WorkSpaces Pool.

A *custom image* contains only the OS, software, and settings for the WorkSpace. A *custom bundle* is a combination of both that custom image and the hardware from which a WorkSpace can be launched.

After you create a custom image, you can build a custom bundle that combines the custom WorkSpace image and the underlying compute and storage configuration that you select. You can then specify this custom bundle when you create new WorkSpaces Pools to ensure that the new WorkSpaces in the pool have the same consistent configuration (hardware and software).

If you need to perform software updates or to install additional software on your WorkSpaces, you can update your custom bundle and use it to rebuild your WorkSpaces.

WorkSpaces Pools supports several different operating systems (OS), streaming protocols, and bundles. The following table provides information about the licensing, streaming protocols, and bundles that are supported by each OS.
