# Running mode for WorkSpaces Pools
<a name="running-mode-pools"></a>

The running mode of a WorkSpaces Pool determines its immediate availability and how you pay for it. You can choose between the following running modes when you create a WorkSpaces Pool:
+ **AutoStop** — Instances of a WorkSpaces Pool are billed an hourly usage fee based on the bundle chosen, only for the instances that are connected to users. Instances within a WorkSpaces Pool that are not connected to users are billed a low stopped-instance hourly fee. When users initiate their session, they start streaming after 1-2 minutes.
+ **AlwaysOn** — Running instances of a WorkSpaces Pool are billed the applicable hourly usage fee, even when users aren't connected. This mode is best for users who don’t want to wait for their streaming to start.
