Will a job run on an AWS EC2 instance if the instance is stopped?

Hi,

We have a set of unattended robots configured in a set of EC2 instances in AWS.
My question is if all of these instances remain stopped by default, will UiPath Orchestrator be able to start the machine and launch a job in any of them? Or should be all of them running by default?

Thanks!

Ideally the machine should be available and bot can login and log out of the machine if the machine is available in the pool

Cheers
