As computing power and storage needs increase rapidly, companies are looking for ways to reduce costs and improve overall return on investment. Although this is not market responsibility, a better understanding of this knowledge would greatly help managers of the companies that are wishing to enhance their current information technology infrastructure. The purpose of this study is to review issues of virtual server consolidation. Factors contributing to the both the positives and negatives associated with the implementation of virtual server consolidation will be evaluated in order to provide increased awareness of this emerging technology. Practical knowledge is discussed to help information technology managers explore this emerging technology for their enterprise information technology infrastructure.

Data centers manage complex server environments, including physical and virtual machines, across a wide variety of platforms, and often in geographically dispersed locations. Information Technology managers are responsible for ensuring that servers in these increasingly complex environments are properly configured and monitored throughout the IT life cycle. They also face challenges managing the physical and virtual environments and the fact that we must centralize, optimize and maintain both. If the variation and complexity can be taken out of a process to make it more consistent, it can be automated. Through the use of virtual provisioning software, provisioning and re-purposing of infrastructure will become increasingly automatic. Staff will physically rack once, cable once, and thereafter (remotely) reconfigure repeatedly, effortlessly, as needed. An automatic infrastructure will rapidly change which servers are running what software and how those servers are connected to network and storage. It will re-purpose machines according to the real-time demands of the business. It will enable capacity to be "dialed up" or "dialed down". And it will bring up a failed server on new hardware, with the same network and storage access and addressing, within minutes. All without needing to make physical machine, cable, LAN connection or SAN access changes.

The case centers on Shilling & Smith's acquisition of Xteria Inc. and the resulting need to quickly scale the company's IT infrastructure to accommodate the acquisition. The case is based on a real leasing problem faced by a major retail firm in the Chicago area when it purchased a small credit card processing firm and scaled the operations to handle the retail firm's credit card transactions. The CIO of Shilling & Smith needs to determine which lease option is the best means of providing the technical infrastructure needed to support the firm after the acquisition of Xteria. Several issues will drive this decision, including the value and useful life of the equipment, as well as the strategic context of the firm. This case examines how to evaluate different lease options when acquiring data center information technology infrastructure. Specifically, the case addresses software vs. hardware leasing, different lease terms, and choosing between different lease structures depending on the strategy and needs of a company. This case enables students to understand the different types of technology leases and in which situations these leases would be employed.The Shilling & Smith case examines how to evaluate different lease options when acquiring data center information technology infrastructure. Specifically, students learn software vs. hardware leasing, different lease terms, and how to choose between different lease structures depending on the strategy and needs of the company. A secondary objective of the case is to teach students the important components and relative costs of information technology infrastructure.

Las empresas, a nivel global, tienden a una mayor dependencia de las Tecnologías de la Información (TI), no solo para el mantenimiento operativo de las instancias de la organización, sino también para el aumento de valor a la empresa por medio de la explotación de datos y sobre todo bajo el análisis y optimización de sus procesos. La metodología Business Process Management (BPM), al combinarlas con las buenas prácticas propuestas por Information Technology  Infrastructure Library (ITIL), permite la posibilidad de aumentar el valor de la entidad por medio de la mejora y adaptación de los procesos desde una perspectiva más ágil, automatizada y robusta con la capacidad de adaptación al cambio, permitiendo a las organizaciones orientar sus procesos al cliente.
