Once you have configured your server hosted on Amazon and started the corresponding instance, you are able to execute one or more Jobs on this server, either by scheduling the Job execution with a trigger, or by running it manually.
On the Job Conductor page, add a task based on the Job you want to execute as explained in Adding a Normal execution task.
Before saving the task creation form, make sure the server you have previously configured is selected in the Execution server field.
Select the newly created task and either add a trigger on it or run it manually using the relevant buttons in the top toolbar of the page, as explained in Scheduling execution tasks.
The Job is being executed on the server hosted on Amazon and the settings you have configured in the Servers page about the actions to be performed after the Job execution are retrieved and applied: according to the option you chose, the Amazon instance is stopped, terminated or keeps running.
