Cloud computing, both private and public, is fundamentally shifting the IT industry and a primary driver of that trend is economics. At Microsoft, we believe that as your private cloud grows, you should benefit from economies of scale. In short, we believe our customers should get the best value with unlimited virtualization rights and lower costs — consistently and predictably over time.
To help our customers get information needed to make the best decisions, last year we published a whitepaper with analysis of how Microsoft’s private cloud delivers the best economics compared to others. We have also created a Private Cloud Economics Tool for you to run a customized analysis of your own environment.
Since the release of both the Whitepaper and Tool, there have been some questions from customers on some of the assumptions and calculations contained within both the whitepaper and Tool. Today, we’d like to take the time to address those questions and help you get the facts about Microsoft private cloud economics. We invite you to read on for a summary of the Private Cloud cost analysis, so you can use our new tool to begin your evaluation of the Microsoft private cloud.
Microsoft private cloud solutions are licensed on a per processor basis with unlimited virtualization rights. Microsoft’s licensing allows you to get the cloud computing benefits of scale with unlimited virtualization and lower costs – consistently and predictably over time. VMware’s private cloud solutions are licensed by either the number of VMs or the virtual memory allocated to those VMs – charging you more as you grow.
This fundamental difference in approach means that with VMware, your costs grow and your private cloud ROI decreases as your private cloud workload density increases. With Microsoft, your private cloud ROI increases, as your workload density does. You can use Windows Server and System Center to build a Microsoft based private cloud solution. System Center 2012 provides a single SKU for an integrated private cloud management solution by integrating eight separate component products into one unified solution. To build a comparable VMware based private cloud solution, you will require multiple VMware products, including:
Some of these suites are bundles of multiple products and every product/suite above except vSphere, vCenter, and Service Manager is licensed on a per-VM basis. This introduces a new VMware tax you can think of as the VMware Density Tax. The graph below shows the impact of VMware density tax VMware charges per VM, so as your VM densities increase, your costs increase significantly, as you end up paying a separate licensing fee for every VM.

When creating our price comparison, we use the most accurate, current, public pricing available, including support on both sides. All comparisons use a publically available, non-discounted product price list, which is refreshed every month. You can find the U.S. Estimated Retail Price List available here. You can also always check the publically available Private Cloud Economics Tool (detailed cost breakdown in the output) that shows we include our support cost, Microsoft Software Assurance, which amounts to 25% of license price/year in our costs.
In the publically available Private Cloud Economics Tool, we have multiple options allowing you to pick the right Microsoft license vehicle for your company. Within the Tool, you choose your inputs and the Microsoft cost output can be either in Windows Server + System Center or Enrollment for Core Infrastructure (ECI), which brings the two together in a Volume Licensing agreement:
We encourage you to try the Microsoft Private Cloud Economics Tool and the Server Virtualization calculator to compare Microsoft and VMware private cloud costs and features.
The IDC Report Delivering Private Clouds today with System Center 2012 sums up our Economics argument- “System Center 2012 directly addresses today's most important private cloud management requirements and provides customers an affordable option for getting started now and for scaling up over time.”
