This paper introduces five architectural principles guiding the development of the next generation data center
(NGDC). It describes key market influences leading a fundamental enterprise IT transformation and the
technological trends that support it. The five principles are: scale-out, guaranteed performance, automated
management, data assurance, and global efficiencies. Cloud infrastructure delivery models such as IaaS, private
clouds, and software-defined data centers (SDDC) are foundations for the NGDC.
