What to Know When Estimating Virtualized Environment Costs
Virtualization, which allows a single piece of hardware to function as multiple “virtual” pieces of hardware, is one of the principal trends for current IT systems. As the technology has matured over the last several years, various organizations in both the public and private sectors have made the transition to operating in a virtual environment in an effort to reduce costs and streamline data access. With server, storage, and network virtualization becoming more prevalent, cost analysts are frequently asked to estimate and assess the costs associated with virtualization.
This follow-on research to the 2009 and 2010 SCEA papers entitled “Cost Impacts of Server Virtualization” and “Server Virtualization and Government Organizations” will provide lessons learned and questions cost estimators should ask when evaluating virtualization cost impacts. A significant segment of the commercial industry has already embraced virtualization, offering a plethora of success stories about dramatic reductions in the cost of operations. However, as the 2009 and 2010 research illustrated, there are several factors which can impact cost savings due to virtualization, especially for government agencies. Factors such as program size, security and mission-critical application concerns, availability of compatible commercial-off-the-shelf (COTS) software, power, space and cooling availability, and program complexity can affect the total cost savings experienced by organizations in the process of virtualizing.
Previous research has focused on the virtualization process for various programs and organizations to determine the magnitude of cost savings that can realistically be expected and establish overarching principles and factors that can be used to assess a program’s future savings due to virtualization. In contrast, this paper focuses on lessons learned and the data collection stage of the estimation process. Through multiple estimates of IT systems that are virtualized or are in the process of virtualizing, as well as continued conversations with industry leaders, it has become apparent that some pieces of information are critical to constructing a sound cost estimate. Because virtualization will impact each organization differently due to unique characteristics and requirements, this paper aims to guide cost estimators through the virtualization estimation process. By understanding important questions to ask and how to best utilize provided information, cost analysts will be better able to assess the hardware, software, facility, and personnel implications of virtualization.
