How to configure multiple agents on a single EC2 instance

Question

I currently have a single remote agent license which runs on a Windows EC2 instance. I used the stock Atlassian AMI which I configured to my liking.

I would like to upgrade my license to include more remote agents, but I'm unsure how I can configure them on my existing EC2 instance. Is it possible to host additional remote agents on that Windows EC2 instance? I couldn't really find any useful information on the wiki.

Or is it only possible to use this with multiple EC2 instances?

Well, yes and no. If you want automated instance management, it sets up each agent on a separate EC2 instance. However, since December last year, you can use remote agents with Bamboo Cloud - this option is more flexible and you can have multiple agents per EC2 instance - but Bamboo will no longer automatically manage the instance lifecycle.

So that means that, if I upgrade my Cloud subscription to include more agents, I also need additional virtual machines? (Which makes it quite expensive.)

That's the part that has been unclear to me.

What I've said applies only to remote agents. You can't run multiple elastic agents on a single EC2 instance. You'd have to prepare an image that starts these agents.
