Amazon is indisputably the biggest name in cloud service providers. They have built up a strong market presence primarily on the argument that access to cheap compute and storage resources is attractive to companies looking to shed IT costs as they move from on-premises solutions to th...
The cloud is one of those technology trends that seems to be perpetually on the cusp of becoming ubiquitous. But if recent analyst reports are any indication, cloud’s breakthrough moment is imminent. Late last year, Gartner predicted that in 2016, the bulk of new IT spend would shift t...
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 conne...
The challenge in architecting, building, and managing data centers is one of balance. There are forces competing to both push together and pull apart datacenter resources. Finding an equilibrium point that is technological sustainable, operationally viable, and business friendly is cha...
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 shif...
There is probably never going to be a perfect balance in the industry between Do-it-yourself (DIY) and Do-it-for-you (DIFY) networking. It seems exceedingly unlikely that there is a one-size-fits-all type of solution out there. And so we will invariably end up with a bifurcated market ...
When we think about what’s next, our frame of reference is almost universally anchored to what we are doing now. We look at how things are, and then we aim our sights forward. In some cases, we might make incremental moves ahead; in other cases, maybe we look for improvement by orders ...
For many SDN and DevOps enthusiasts, the natural outcome of this wave of technological change is a highly-automated network that is well-orchestrated with surrounding systems and applications. One of the prevailing thoughts is that this level of automation is a well-formed abstraction ...
The overall networking landscape has been going through a fairly deliberate shift over the past couple of years. Where we used to talk CapEx, we are now talking OpEx. Where we used to talk features, we are now talking about workflows. This change in industry dialogue mirrors the rise o...
SDN is almost universally associated with disruption; the general consensus being that it is a significant departure from the way networking has been handled for decades. Insofar as SDN marks a major architectural shift, it absolutely should be considered a disruption. But how does dis...
A little over a year ago, Plexxi set up shop on the west coast, opening an office in San Francisco. This past week, that office got a little more crowded. Nick Vitro has joined the team, to lead Plexxi’s sales efforts in the Web Services business segment. That Plexxi is growing i...
The most challenging part of managing a complex IT infrastructure is not in the silos but the boundaries between those silos. Tools, processes, and even people have to be particularly flexible at the points where workflows intersect. And once these intersection points are codified (th...
With the launch of Cisco’s software-defined networking startup Insieme expected tomorrow, our industry is about to hear a lot about “application-centric” everything. So what does “application-centric infrastructure” mean? First, some basics: Networking is about connecting computing de...
Companies that do not plan for this type of convergence will be caught horribly flat-footed. The kinds of changes we are talking about are measured in years, not weeks or months. The personnel, organizational, and cultural impacts of changes like this are striking. How much more diffic...
The bad thing about price differentiation is that it is also the most easily countered. What happens if Cisco announces dramatically lower price-per-port when they spin Insieme in? They don't even have to beat Arista; they just have to be close enough that the price part of the equatio...
