Latest Blogs from SDN Journal
In my first post, I discussed how software and various tools are dramatically changing the Ops department. This post centers on the automation process. When I was younger, you actually had to build a server from scratch, buy power and connectivity in a data center, and manually plug a...
Certainly, enterprises feel the pressure to transition their networks to next generation architectures like SDN to brace the coming storm that is an app economy. Service providers could provide valuable advice to them on how to do that, if they could yell loud enough over the thunderou...
When I took my operating systems fundamentals course in college I was taught that an operating system provides very specific capabilities that provides users with access compute resources for building and running applications. Over time as networking capabilities and bandwidth increase...
DevOps is a discontinuous innovation in the way organizations develop and deliver software. And as with any new discontinuous innovation, the implication is that creative destruction will follow. Companies that hold on to legacy business and technology models, without pursuing the ev...
#HTTP #HTTP2.0 Why that version number is so very important .... It's no surprise that HTTP is the new TCP. Inarguably, more applications are delivered via HTTP than any other. That's including mobile apps, by the way, which are more often than not using HTTP to talk to REST-based API...
#DevOps #SDN And more importantly, what can I do with it?  So within the realm of software-defined (everything) and DevOps one can find lengthy (and often in depth) discussions on the relevance and indeed importance of programmability to both. In the case of SDN, programmab...
I ran across this quote a while back, and was awestruck at its profundity. I keep it on a list of quotes that I look to for inspiration. To think that the guy who invented the theory of relativity views the world in this way, trying to distill extremely complex ideas down to their simp...
Logging as part of the continuous delivery process can help your teams move faster and build a product that your customers really love. Over the last years Continuous Delivery has gained a massive following with many development teams embracing the style. Companies have chosen (as wit...
Throughout the development cycle of new features and functions for any network platform (or probably most other products not targeted at the mass market consumer) this one question will always come up: should we protect the user of our product from doing this? And “this” is always some...
When SDN made its mainstream debut at Interop in 2012, there was quite a bit of excitement tempered by the reality apparent to some folks that technical limitations would impact its applicability above layer 2-3 and, perhaps even at layers 2-3 depending on the network. But even then w...
While some might still be focused on SDN with an OpenFlow-style twist, 30% of the organizations in our survey this summer (report forth coming, I promise!) were looking at SDN to improve time to market. Of those, 73% considered an API-enabled infrastructure to be important to very impo...
#SDN #DevOps Stateful is not stateless. And vice-versa.  
As one of Heroku’s beta users I had the chance to check out the new Heroku button gallery last week. I must say I was very pleasantly surprised. Over the past few years, it’s fair to say Heroku have nailed their PAAS offering. They are one of the few PAAS providers to truly succeed in...
I remember when we first started talking to customers about the concepts of applications driving networks, about 3 years ago (This was a very different conversation from other networking era’s where we talked about ‘intelligent’ networks that could better understand and adapt to applic...
With the capability to reduce both CapEx and OpEx, it’s easy to see why the SDN-NFV trend has taken hold in the hosting and mobile industry. Early use cases include network virtualization from cloud service providers and enterprise data centers, bandwidth calendaring and network tappin...
Software-defined networking is fundamentally about two things: the centralization of network intelligence to make smarter decisions, and the creation of a single (or smaller number of) administrative touch points to allow for streamlined operations and to promote workflow automation. T...
We (as in the industry at large) don't talk enough about applying architectural best practices with respect to emerging API and software-defined models of networking. But we should. That's because as we continue down the path that continues to software-define the network, using APIs an...
Executives charged with building business-driven applications have an extremely challenging task ahead of them. However, the cavalry has arrived with useful tools and strategies built specifically to keep modern applications working efficiently. We partnered with Gigaom Research to ca...
Inarguably, the pressure is on "the network" to get in gear, so to speak, and address how fast its services can be up and running. Software-defined architectures like cloud and SDN have arisen in response to this pressure, attempting to provide the means by which critical network servi...
It’s been a busy week here at Plexxi. On Tuesday, we announced our partnership with Cari.net, a high-performance, scalable and flexible hosting platform based on Microsoft Cloud OS. CARI.net’s newly released CARIcloud service is powered by Plexxi and uses software-defined networking to...
There are two major technology trends that have the potential to move the networking industry away from managing discrete devices and instead thinking of the network as a single distributed system. Software-defined networking (SDN) aspires to manage through centralized control, and Dev...
Combined Company Offers Powerful Suite of Dynamic Access Management, Data Security and Compliance SolutionsBoston, MA / Gothenburg, Sweden - September 5, 2014 - Cryptzone, a global provider of data security and identity and access management (IAM) solutions, has acquired HiSoftware Inc...
A good friend and business colleague once regaled me with his definition of a good corporate lawyer: “A good lawyer never says ‘no’; she says ‘here’s how’.” I thought this was an interesting and telling description – not because it conjured up creative interpretations of the law and lo...

Elasticity is hailed as one of the biggest benefits of cloud and software-defined architectures. It's more efficient than traditional scalability models that only went one direction: up. It's based on the premise that wasting money and resources all the time just to ensure capacity on ...
