I have a CPU intensive EC2 app, but it only gets accessed for a few hours during the day by a single client. I'd rather not leave a high-cpu instance running constantly - is there a way to lower my usage of the instance?
I'm assuming I need to have one instance (perhaps a small one) constantly running to have something to check for traffic... and then set up something that start/stops the high-cpu instance, and forwards traffic.
What is this called? Where do I find information on configuring this? (Is this something I can do with apache under ubuntu?)
