I'm trying to save our AWS cost. What I am doing right now is to terminate ec2 instances at 8pm then launch them again at 8am. I was able to do this via Skeddly (http://www.skeddly.com/).
The problem is the codes are not update every time I launch an instance because I'm just using an AMI. What I want to find out is, are there any services which I can use to auto deploy codes using CodeDeploy every 8am so that the instances are aligned with the latest codes.
