# Scheduler
You can use the scheduler to automatically wake up your Cloud machines or to schedule downtime for maintenance.
* **Waking up** machines before you need them can help your developers access cloud machines without having to wait for them to wake up. However, if they are not used by the **VM idle timeout** defined in the cloud settings they will go back to sleep. This can also be done on demand using our [API](/cloud/start-pool-machines).
* Scheduling **agent maintenance** is important to allow the cloud machines to update their operating system. We recommend doing this once every 2-4 weeks. The cloud machines are automatically returned to the pool after they have either updated their operating system, or discovered that there is no available update.
## Schedule an Action
1. Go to your **Coordinator** > **Cloud** > **Edit Cloud Settings**. This may vary slightly with different versions of Incredibuild.
2. Go to the **Scheduler** tab and click 
.
3. Select **Agent Maintenance** or **Wake up Agents** as the **Action Type**.
4. Define the time of the action using the **Recurrence**, **Date**, and **Time** fields.
5. Finally, click **OK**.
