Software defined networking (SDN) has been in the spotlight since its conception in recent years because of the revolutionary potential that this emergent technology has for the future of IT networking. SDN is like a testament to the changing times. It is a confluence of several of the...
Before June 29th, 2007, if you asked someone what kind of phone they had they would likely have answered with a manufacturer's name or brand: Motorola, Blackberry, Nokia. In September 2008, Google unleashed Android on the world and everything changed. Today, phones are primarily identi...

Don and I have four children, all of whom have had the fortune to take piano lessons (I'm not sure if the youngest would agree he's fortunate at this point in his life but at five, he's not really able to answer the question with any degree of wisdom, anyway. Come to think of it, not s...

#SDN #API #devops What is it that applications want, and more importantly, what of those desires can the network fulfill? That's one of the questions SDN has to answer in order to make SDN relevant in the big picture that is the software-defined data center. What is it, other than...

The age of data center automation is upon us. Whether it's cloud or SDN or devops in general, automation as a means to achieve efficiency and, one hopes, free up resources that can be then redirected to focus on innovation. As is always the case when we begin to move further upwards...
When Lori and I were writing import/export routines for a large software vendor, we had a phrase to remind ourselves that what we loved was not necessarily the all-important part of what we were doing. We used to say “It’s all about the data”, almost as a mantra, to keep our team (I wa...
ViPR is not a technology creation developed in a vacuum instead includes customer feedback, wants and needs. Its core themes are extensible, open and scalable. What is ViPR addressing? IT and data infrastructure (server, storage, IO and networking hardware, software) challenges for t...
One of the major challenges facing organizations as they grapple with increasing traffic, users, devices, and applications is managing the connective tissue that enables the users, devices, and applications to communicate. This was already a growing problem when virtualization and then...
As with most new exciting (read: hyped) technology there's always some initial fragmentation that occurs in the market. Everyone wants to have their fingers in the newest pie and from that comes what musicians call "variations on a theme." The melody is the same, but the harmony and ch...
I was researching something totally unrelated today, and happened upon a couple of things that made me decide to write a quick blog about SPDY support and the tools available to you relevant to SPDY. First, I found a ton of administrators asking how they could verify that SPDY was bei...
We were serious about getting serious about managing hybrid cloud and federating application network services Last month I brought up the need to manage application network services - load balancing, acceleration, optimization, application security.. you know, application services tha...
This weekend I was at LinuxFest Northwest in Bellingham, Wa. I had the opportunity to see a lot of interesting talks. Here’s the talk I gave LinuxFest NW 2013: Hitchhiker’s Guide to Open Source Cloud Computing . Abstract: Imagine it’s eight o’clock on a Thursday morning and...
Don't laugh or next week we'll talk fractals and tessellations and nature and tie that back to ERP. Somehow. Don't tempt me. I'm not kidding. The other day I was shopping (on-line of course, because you know, Internets) as I often do: I was putting things into my shopping cart and o...
Lori and I were discussing the entire topic of agility the other day, she looking at it from the SDN prospective, and I from the evolutionary perspective for development. While I know there has been a metric ton of writing about the topic, since I’ve used agile development, and find it...
When it comes to talking IT operations and financial considerations I tend to stay away from deep economic theories. I'm not Joe Weinman, after all. But I happened upon (no, I don't recall how so don't even ask. The Internets, you see) an 1850s essay on political economics written by ...
DNS, like any public service, is vulnerable. Not in the sense that it has vulnerabilities but vulnerable in the sense that it must, by its nature and purpose, be publicly available. It can't hide behind access control lists or other traditional security mechanisms because the whole poi...
Yes, I'm about to say something that's on the order of heresy in the church of virtualization. But it has to be said and I'm willing to say it because, well, as General Patton said, "If everyone is thinking the same... someone isn't thinking." The original NFV white paper cited in t...
Riding the current software defined data center (SDC) wave being led by the likes of VMware and software defined networking (SDN) also championed by VMware via their acquisition of Nicera last year, Software Defined Marketing (SDM) is in full force. HP being a player in providing the c...
Today the Linux Foundation announced their newest collaborative project, the Open Daylight Project. “Daylight” is an open source project formed by industry leaders and others under the Linux Foundation with the mutual goal of furthering the adoption and innovation of Softwa...
If you're immersed in the world of service providers (sometimes called carriers, telecoms, or carrier service providers) then you've probably heard the term "traffic steering." Traffic steering is the ability to control and direct data and voice traffic to the best suitable cell layer a...
One of the primary reasons node.js is currently ascending in the data center is because of its core model: event-driven, non-blocking processing. Historically, developers write applications based on connections and requests. It's blocking; it's not asynchronous; it's not fire and forg...
It's the "do not disturb" sign on the hotel door.... I admit it. I'm guilty of using self-referential definitions when discussing the topic of programmable networks. Somehow, while trying to define what a programmable network is, I end up using the term "programmable". Because that s...
When first you build a bookshelf from raw wood, on your own, you learn a lot. While the first may be the only one you ever want to build, by the time you’re done, you know you could have done X, Y, or Z better. This is true of so many crafts. You get better by doing, in large part beca...
Where has the FCoE hype and FUD gone? (with poll) By Greg Schulz A couple of years ago I did this post about if Is FCoE Struggling to Gain Traction, or on a normal adoption course? Fast forward to today, has anybody else noticed that there seems to be l...
Energetic debates of what SDN is and the expanding scope of what it can do for our customers continue to race along in a chaotic frenzy. In addition, the overall SDN market is somewhat fragmented in terms of both vendor positioning and marketing. Collectively, the conversation really ...
New ODCA Solution Provider Member To Promote Open, Interoperable Cloud Computing StandardsCHICAGO, IL - March 13, 2013 - CohesiveFT today announced it has joined the Open Data Center Alliance (ODCA), a distinctive consortium of global IT experts committed to being a unified voice for e...
If you’re like most people, when you notice something really odd about your body, the first thought to enter your brain is not “I need to call the doctor”. Of course let me clarify, if you look down after a fall, and think “My arm really shouldn’t bend like that”, then yeah, you call a...
Quiescence, in a nutshell, is your mom telling you to "finish what you're doing but don't start anything new, we're getting ready to go". It's an integral capability of load balancers (of enterprise-class load balancers, at least) that enables the graceful shutdown of application in...
This week F5 released the 2013 Performance report. This is an important report for the industry, because it is not marketing slideware. It is actual tests, performed on actual gear, with not only results, but configurations and test environment information also. By design, it is open –...
When assembling a model – any model, from a highly detailed functional replica of an engine to a mass produced plastic model of an airplane – there are several places where things can go wrong. The final product is only as good as the model kit, the glue used, the tools used, and the s...
#webperf #infosec #ado #SDN #cloud Service chaining is a popular term today to describe a process in the network that's been done in the land of application integration for a long time. Service chaining in a nutshell is basically orchestration of network services. This concept is ...
Leah Schoeb of The Evaluator Group, wrote a nice piece about storage benchmarking that we highly recommend. I won't reiterate her article here, but I would like to simply point out that the specs many vendors throw around don't come with the appropriate caveats. They don't mention blo...
Since SDN became the darling du jour of the networking industry, there's been a lot of head nodding and ancillary mention of L4-7 services eventually becoming part of the overall fabric. What there hasn't been is a lot of discussion on the challenges inherent in bringing those services...
BROADBAND CONVERGENT - Business News Broadband-Mobile-Cable-Telecom MarketsToday, the company introduced a wave of product innovation that covers a vast spectrum of needs within data center and cloud environments – from the Cisco Nexus 6000 Series Switches, the industry’s highest den...
One of the premises of SDN and cloud scalability is that it's easy to simply replicate services - whether they be application or network focused - and distribute traffic across them to scale infinitely. In theory, this is absolutely the case. In theory, one can continue to add capac...
