Hi, we used Scalarium from Peritor, which is now AWS OpsWorks, and this worked very well for us. You basically create CHEF-scripts to define type of servers and group different types of servers to clouds (e.g. web server, DB server, load balancer, monitoring server, app server, memcached server etc.). Once this is done you can easily start/stop instances either manually or automatically triggered by an event (time-/load-based). We managed 500+ servers with this solution. If you don't like AWS OpsWorks, you can still use Chef or any of the other IT-Automation-Tools (puppet, vagrant, ...) Best Thorsten
