Define and Virtualize

Infonetics research predicts that the NFV and SDN markets will reach $11 billion globally in 2018. SDN and NFV are the tools and enablers that can match network capacity to evolving needs in real time. Software-based network control with SDN, and virtualization of network "appliance" functions with NFV, will enable self-service control of network capabilities and new pay-per-use consumption models. They will also lead to provisioning of networks in minutes, not days or weeks, with automated and orchestrated changes and network policies that follow the workload.

In the days when businesses expanded through brick-and-mortar investment, entrepreneurs and business leaders were able to control how fast people were able to access their services, and scale up smoothly in response. In more recent years, social media and the rise of on-demand video, online gaming and over-the-top services has ushered in an age of viral growth. Gracefully supporting the "going viral" nature of our world is what the next generation of networks is all about, and it is starting to affect enterprises as much as content providers.

A "web-scale" network is one that can get big, fast, to keep up with these trends. The term was first used to describe the data center and content distribution architectures used by Internet content providers, who needed to build these architectures to service hundreds of millions, if not billions, of users. Enterprises are now leveraging similar design practices to address the "always on" challenge as more of their applications are migrated to the cloud. According to Gartner, web-scale IT will be an architectural approach found operating in 50 percent of global enterprises by 2017.

The following slideshow from Rick Dodd, senior vice president of portfolio marketing and strategic market development, Ciena, chronicles the key steps network providers must take to web-scale their networks to support the size of the web and viral nature of our world.
