Cloud Whitepaper: Virtual Network Architecture
Looking back at how the IT landscape has evolved over the past 20 years, it is amazing to see the striking parallel between the evolution of technology and the evolution of business. In the Client /Server era, it was normal for IT initiatives to take months or even years on end. This was reflective of the pace of business at that time; it seems the whole world ran at a slower pace as purchasing behavior was still dictated by the physical world and global competitors were separated by vast distances. As industry transitioned into the Internet era, the world became increasingly flat, new business models emerged and new competitors from around the globe became as close as a mouse click.
The amazing technological progress that has led industry through the Internet and into the Cloud era was made possible in large part by the advancement of open innovation in the server and software industries. The open x86 architecture, powered by Moore’s law, has unleashed unparalleled innovation and value over multiple generations of microprocessor technology. Similarly, the open x86 software industry has grown to provide revolutionary advancement in every facet of business and industry. Server virtualization has further unleashed value by enabling on-demand resource availability, asset efficiency and business continuity.
In contrast, the Networking industry has yet to benefit from such open innovation initiatives. Unlike the open x86 market, there is no modern software development ecosystem for the leading network operating system; there are no modern standards for intelligent programmable interfaces to enable automation; virtualization is primitive, static, and fractured.
This whitepaper outlines the principal elements of VNA and maps out its principal applications for traditional, virtual and cloud IT environments.Dell‖s Virtual Network Architecture (VNA) framework is a direct response to this growing need for networking solutions to be brought into the modern age. VNA is designed to be both innovative and practical, based around a set of open, flexible architectures that provides the benefit of the latest innovations in networking. VNA is also designed to integrate tightly with innovative new network virtualization solutions such as the Hyper-V Network virtualization framework jointly developed by Microsoft and Dell.
