The cost of cloud computing solutions, much like the scenarios of cloud computing configurations themselves, can vary tremendously. You can spin up a public cloud for perhaps as little as $100 and private cloud perhaps approaching $5,000.

Recently, ASG conducted a detailed financial analysis of three cloud computing solutions: 1) public cloud from Amazon EC2; 2) purchased private cloud infrastructure; and, 3) a leased private cloud infrastructure. Here’s what we found:


Based on our analysis, a private cloud computing solution whether leased or purchased would seem the way to go. In addition to the financial benefits, we feel that there’s a propensity for additional flexibility and greater uptime.

This analysis shows a $513,295 cumulative cost savings over three years for the private cloud purchase versus the public cloud option. The private cloud lease saved $489,874 versus the public cloud option over the same three years.
