Hey @rahul.bhoyar,
Thank you for contacting Octopus Support, Octopus does not have anything out of the box that does this, however, I imagine there are some AWS CLI script commands you can use to turn off and on machines so you would have to have Octopus run a script step to turn the machine on with an AWS CLI script, then perform the task you want, then have another run a script step to have the machine turned off via an AWS CLI script again.
Octopus can deploy to AWS AGS (Auto Scaling Groups) so if that is something you wanted to check out then we have a blog post on this here, and also a forum knowledge base on this here but that would be for scaling up and down and not for one instance so it would depend on your requirements as of if that was any use to you or not.
Hopefully that helps,
Kind Regards,
Clare
