E. Commoditization
F. Economics
Correct Answer: ACD

Explanation:
Data center transformation takes a step-by-step approach through integrated projects carried out over time. This differs from a traditional method of data center upgrades that takes a serial and siloed approach.[9] The typical projects within a data center transformation initiative include standardization/ consolidation, virtualization, automation and security.
Standardization/consolidation: The purpose of this project is to reduce the number of data centers a large organization may have. This project also helps to reduce the number of hardware, software platforms, tools and processes within a data center. Organizations replace aging data center equipment with newer ones that provide increased capacity and performance. Computing, networking and management platforms are standardized so they are easier to manage.[10]
Virtualize: There is a trend to use IT virtualization technologies to replace or consolidate multiple data center equipment, such as servers.Virtualization helps to lower capital and operational expenses,[11] and reduce energy consumption.[12] Virtualization technologies are also used to create virtual desktops, which can then be hosted in data centers and rented out on a subscription basis.[13] Data released by investment bank create virtual desktops, which can then be hosted in data centers and rented out on a subscription basis.[13] Data released by investment bank Lazard Capital Markets reports that 48 percent of enterprise operations will be virtualized by 2012. Gartner views virtualization as a catalyst for modernization.[14]
Automating: Data center automation involves automating tasks such as provisioning, configuration, patching, release management and compliance. As enterprises suffer from few skilled IT workers,[10] automating tasks make data centers run more efficiently.
Securing: In modern data centers, the security of data on virtual systems is integrated with existing security of physical infrastructures.[15] The security of a modern data center must take into account physical security, network security, and data and user security.
