I need to run a custom-made software authentication system in the cloud and I was considering buying an Amazon EC2 (probably t2.micro) instance on demand. I will also need an elastic IP address since users will have to find my instance through a DNS.
What I'm wondering right now is the following: I couldn't get how it works with the on-demand model. Will the machine be put to sleep when there are no requests as it happens with the red-hat free cloud? Will that then require several minutes to restart? (I can't afford users to wait for their software to be authenticated for several minutes)
And finally: will the elastic IP address wake up the machine when a request comes?
I could find no piece of documentation regarding these issues
