Software Defined Application Services (SDAS) are going hybrid. . Organizations are turning to cloud not just as an option for applications but also for the network and application services that deliver applications to anyone, anywhere at any time. And not just "in" the clo...
Operationalization (which is really hard to say, go ahead - try it a few times) is a concept that crosses the lines between trends and technologies. Both SDN and DevOps share the notion of "operationalization" as a means to achieve the goal of aligning IT with business priorities, like...
With the blurring of technology lines, the rise of competitive companies, and a shift in buying models all before us, it would appear we are at the cusp of ushering in the next era in IT—the Third Platform Era. But as with the other transitions, it is not the technology or the vendors ...
We are getting into the Halloween spirit here at Plexxi—check out this Plexxi pumpkin carved by our talented marketing manager, Khoa Ma! Jack-o-lanterns aside, we know the thought of navigating trends like the Internet of Things and Big Data can be frightening, especially if you are un...
Although the concepts of continuous delivery are well known, organizations with existing applications looking to implement CD still have a lot to consider. Customer demands aren't the only thing pushing development and operations teams into more frequent software releases. It is also ...
My entire career has been spent finding disruption and cultivating the technologies needed to convert that disruption into real business value for customers. It is with that objective in mind that I am thrilled to join the Plexxi team as Chief Executive Officer, alongside my good frien...
You have probably realized we are having a Big Data kind of week here at the Plexxi blog. And for good reason. The amount of development and change in this big bucket of applications we conveniently label “Big Data”, is astonishing. Walking around at Hadoopworld in New York last week, ...
The Internet of Things is only going to make that even more challenging as businesses turn to new business models and services fueled by a converging digital-physical world. Applications, whether focused on licensing, provisioning, managing or storing data for these "things" will incre...
I am sure our work environment is not all that different from many others. There are large whiteboards everywhere and you cannot find a meeting room that does not have circles, lines and squares drawn on them. Some of our favorite bloggers have written blogs about network drawing tools...
Companies that until recently had never heard of the Internet of things (IoT) are now excited to find that they’ve been IoT players all along. Businesses involved in home automation, security services, vehicle tracking and health monitoring to name a few have been around for a while. T...
Kirk Byers at SDN Central writes frequently on the topic of DevOps as it relates (and applies) to the network and recently introduced a list of seven DevOps principles that are applicable in an article entitled, "DevOps and the Chaos Monkey. " On this list is the notion of reducing var...
With the growing number of CSS Preprocessors like LESS, Sass, Turbine, Stylus and Swith CSS to name a few, it’s hard to decide which to choose for your project, and which will provide the best CSS authoring. Rather than focus on evaluating every CSS Preprocessor (that would simply take...
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...
#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...
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...
#SDN #DevOps #Agile A syzygy is an astronomical term that describes the alignment of three celestial bodies within a gravitational system. The alignment of three celestial bodies (app dev, ops, the network) within a gravitational system (IT). The data seems to show some alignm...
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...
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...

Over the past few weeks I have had several conversations related to calculating network topologies and how packet forwarding is done based on those topologies. I wrote this post about a year ago explaining some of these details, but after a conversation with a customer earlier this wee...
There is no doubt that software defined networking has the power to improve network performance on college campuses. University networks demand flexible and reliable solutions and many institutions are turning to SDN to save time, increase efficiency and reduce IT costs. A few of the a...
User Experience (UX), in networking is a tricky thing. It’s not just about the direct user interaction of a particular feature or of a particular product. Over at Packet Pushers, we see many blog entries reviewing network products. Time and time again, they show us that UX encompass...
In the five seconds it takes you to read this, 60% of your visitors just abandoned your site. Another 20% were gone before you even hit the first comma, and 30% of all them are purchasing from one of your competitors. That's what Limelight Networks "State of the User Experience" says,...
In a previous article, we talked about “Short T’s.” We talked about how, in network engineering, the “T” is very long: Configuring a network to achieve business goals requires considerable skill and knowledge. While we set up a conceptual model in that post to talk about what “T” me...
As SDN gains traction within the private sector we are also seeing federal agencies adopt it as they identify the need for network infrastructure changes. While it may be instinctual to say ‘yes’  to upgrading the network to include every new additional feature offered, especially when...
#SDN #SDAS There's a whole lot more to software-defined networking than OpenFlow... There's a lot of gnashing of teeth and gnawing at industry reports over the apparent reluctance of organizations to jump with both feet into the SDN ring. According to a new QuinStreet Enterp...
