Review on PowerDown by Justin Sherman

I like that it automatically moves your application to spot when you have more demand than capacity for an instance so as not waste money paying for unused server time, this is great! However sometimes its hard getting updates from them or they don't respond immediately if there's something wrong, but other then those things i dont dislike anything about their product at all! It has saved me tons of cash in my organization by moving our applications off of very costly VMs we were constantly having issues keeping up with because everyone was using too much memory etc., into cheaper EC2 spot VM which are almost always free (at least compared to what it used be costing us).
