OpenFlow and SDN in 2012 – A Look Back
Before starting to discuss where 2013 will take us with SDN, I’d like to recap some of the significant SDN events for 2012. Below is a breakdown of the major events in chronological order.

Effectively a next generation load balancer, enterprises are deploying Application Delivery Controllers (ADCs) to front-end their mission critical applications. The enterprise ADC market is mature with well established players and solutions. Yet when moving applications to the cloud – it’s a completely different playground. The business need is to support a new application life cycle—one that allows the business to scale across hybrid cloud environment.
In this post I will explore an application life cycle use case across hybrid cloud, and how to properly deploy an ADC in the cloud to support the application life cycle.

A couple of weeks ago I returned from a business trip to Korea and China where I met with a number of customers and partners from various vertical markets. The most interesting thing about this trip was that these two countries continue to encounter huge increases in their Internet traffic due to steady, on-going online business expansion. The customers I met with included an online payment services company, various leading mobile carriers, a large bank and a cable network operator among others. What I found common to these companies is that almost all of them are considering their next-generation strategy with regards to their data center technologies and operations. And while each customer obviously has a different environment with distinct applications and infrastructures it was clear that they are all keen on delivering one thing – an optimized Web experience.

As the industry and the media keep feeding the Software-Defined Networking (SDN) hype and vendors introduce SDN products into the market – it is becoming increasingly important to understand the difference between various offerings as well as the ways in which they can help end users.
The majority of the discussion has centered on changes in forwarding functionality – the functionality of forwarding packets between interconnection ports of networking devices. With OpenFlow (which is not SDN, but is what triggered a lot of the SDN discussion) the intelligence making the forwarding decisions, which lies in the control plane, has moved out of the forwarding platforms that connect the external systems into the network and into the controllers. Here we have decoupled OpenFlow switches and controllers.
How Big Do You Have to be to Afford a Disaster Recovery Solution?
The devastation wrought by superstorm Sandy is a stark reminder of just how fragile our environment is versus the power of nature. In just a couple of days, a single storm disrupted the lives of so many people and paralyzed a large number of businesses even days after it passed. In the wake of the storm, one of the questions on my mind is, how can we help businesses remain functional after such a massive hit regardless of their size?
Working for an Application Delivery Controller company, I’m no stranger to disaster recovery. Most often, disaster recovery is initiated by large enterprises that invest big money to build entire backup datacenters with the ability to automatically provide all online services in case their main datacenters become unavailable. A reality faced by many businesses in and around New York after the storm.
