To minimize the number of steps such as hardware purchasing or testing used to set up web servers of different administrations, the Division of Network Systems adopts the technology Network Virtualization. Network Virtualization is an architectural approach to securely service different administrations on a common infrastructure with shared services and shared security devices. Virtualization of the network provides multiple solutions for centralizing services and information technology (IT) while preserving the high-availability, manageability, security, and scalability benefits of the existing campus design.
