The cloud is changing how technology is being consumed, and data centers are struggling to keep up.
The old model of technology consumption consisted of ordering something and waiting for it to be ready. The cloud has replaced this model with on-demand for just about everything, and this is requiring the data center to shift, expand, even contract far faster than its legacy designs allow.
That’s because while computing has shifted to a virtualized model, where computing resources can be instantiated at almost a moment’s notice, the networking hardware that supports this computing is not nearly as flexible.
Data centers are suffering from several problems, according to a recent webinar, Realizing your Cloud's Full Potential Nuage SDN, by Nuage Networks principle solutions architect, Dave Twinam. These include the data center being an island of connectivity and not using resources efficiently, complication from device-by-device configuration and minimal programmability, and the challenges of largely being run by single-vendor, proprietary solutions.
All of these can be solved by software-defined networking (SDN), which Nuage aims to provide.

The idea of SDN is basically to virtualize not just the computing functions, but also the networking hardware within the data center. Nuage Networks does this through a virtualized services platform composed of three major components.
The first component is the Nuage Networks Virtualized Services Director (VSD). The VSD delivers virtual service definition, policy establishment, service templating and analytics engine and reporting. This abstracts complexity.
The second component of the solution is the Virtualized Services Controller (VSC), which is an SDN controller powered by a service routing operating system. It has peering and federation, auto-discovery for automation, and tenancy slicing. This programs the network and comes with rich routing functionality.
The third major component of the Nuage Networks solution is Virtual Routing and Switching (VRS). VRS is a Level 2 to Level 4 virtual switch. It is open V-switch based and provides both VXLAN and MPLSoGRE tunnel encapsulation. It can be programmed through OpenFLow from the VSC, and encapsulates virtual machine flow into the preferred protocol. It also detects virtual machine instantiation and teardown to adjust automatically as the system changes.

The solution brings a policy- and template-based workflow to the data center that helps both virtualize and automate the networking infrastructure that currently slows down most data centers.
With user demand increasingly on the uptick, the data center can no longer afford a slow and manually-configured network infrastructure. Which is where SDN and the Nuage solution come into play.
