On Premises, Virtual, Cloud Solutions and a New Network Design Paradigm

Traditional computer network design decisions are changing. There are several reasons: the technologies themselves that are used in networks have changed, the general concept for designing network is considered for a network infrastructure, in which services are considered an integral part of the network; the general approach to describing the network has changed from component to object and service, new solutions have appeared for transferring services to virtual and cloud spaces. The trends of ongoing changes are considered and real solutions are described when designing a change in the infrastructure of a computer network. Trends are considered on the example of networks with different scales. As a result, the changed network design paradigm is reduced to four areas: network design for on-premises network, network design for virtualization approaches, large network design for cloud services, and LAN design for personal space.
