When people talk about Big Data, the emphasis is usually on the Big.
Certainly, Big Data applications are distributed largely because the size of
the data on which computations are executed warrants more than a typical
application can handle. But scaling the network that provides connectivity
between Big Data nodes is not just about creating massive interconnects.
In fact, the size of the network might be the least interesting aspect of
scaling Big Data fabrics.
Just how big is Big Data?
Not that long ago, I asked the question: how large is a typical Big Data
deployment? I was expecting, as I suspect many people are, that the Big in
the title meant that the deployments would be, in a word, big. But the
average Big Data deployment is actually far smaller than most people realize.
I grabbed a list from HadoopWizard in an article dating back to last year.

The benefits of automation are well understood: more agile service
provisioning, faster time to insight when there are issues, and a reduction
in human error as manual interaction is reduced. Much of the premise behind
long-term SDN architectural advantages is steeped in the hope that SDN will
help enable and ultimately promote automation. But while centralizing control
has significant operational advantages, by itself, it doesn’t actually
address the most important requirement for automation.
If automation is going to be more than just reducing keystrokes, there will
have to be... (more)
Everyone experiences challenges at work. Whether it’s an individual
contributor or the CEO, everyone has to go through the same basic set of
issues that plague virtually all workers everywhere. But not everyone handles
those problems the same way. Conversation is the usual outlet for most
people. But how you conduct those conversations says a lot about you. The
question during these conversations is: Are you a doctor or a patient?
Doctors and patients
We have all been a patient at some point or another. Regardless of how smart
or rich or powerful we are, we walk into that little e... (more)

Software Defined Networking (SDN) has quickly spawned what appears in some
respects to be a cottage industry of would-be disruptors to the more
traditional networking approaches. With hundreds of millions of dollars in
venture capital flowing into the space and dozens of infrastructure companies
now vying to be the preeminent SDN vendor, how can anyone — customers or
investors — predict who the breakout players will be?
SDN is a How, Not a What
The most basic thing that potential customers and investors need... (more)
Compute started its major architectural transition several years ago with the
introduction of virtualization. If you pay attention to any of the IT noise
today, it should be clear that storage and networking are going through their
own architectural evolutions as well. But another shift is also underway:
applications are fundamentally changing as well.
An interesting dynamic in all of this is that it is near impossible for each
of the four major IT areas to undergo simultaneous, coordinated evolution.
Change is hard enough on its own, but changing multiple variable at once
