One of the most important benefits is that a company can optimize resources because Auto Scaling deploys resources when needed. For example, for Black Friday, a company can deploy 100 servers for a couple of days. When Black Friday is over, the company can delete those servers.

We have found that the sizing in Amazon EC2 Auto Scaling is far off. For example, we will see some at one terabyte and the other one is two terabytes. There is nothing between one and two terabytes. Sometimes it's a struggle if I need one and a half, I still am supposed to pay for two. There are five terabytes, six terabytes, and 12 terabytes, and if I need something at eight or nine, I'm still paying 30 to 40 percent more by taking the one which is 12 terabytes. Microsoft Azure does similar sizes but the gap can be more, such as six terabytes, and the next one is 12 terabytes.
