When it comes to wide area networking, large global enterprises have some unique challenges to ensure that networking capabilities keep up with their complex business requirements. The most obvious challenge is the sheer scale of WAN operations. A very large enterprise could have hundr...
Software-defined is a concept that refers to the ability to control some or all of the functions of a system using software. The concept is sometimes incorrectly characterized as a buzzword or marketing jargon, when in fact it has a clear meaning that needs to be understood by organiza...
Data Infrastructure server storage I/O network and associated tradecraft are your skills, experiences, insight as well as tricks of the trade, profession and job function (read more about what is a data infrastructure here). This is the first of a two-part series exploring data infrast...
Each enterprise - and perhaps even units within each enterprise - is determining the path to a proper mix of public and private cloud. Implementing such a services-attuned architecture may be the most viable means to dynamically apportion applications and data support among and betwee...
In his session at Cloud Expo, Robert Cohen, an economist and senior fellow at the Economic Strategy Institute, provideed economic scenarios that describe how the rapid adoption of software-defined everything including cloud services, SDDC and open networking will change GDP, industry g...
So you’ve heard how click-to-call widgets can really enhance a website’s potential for customer interaction and you want to try it out for yourself. Or you’re considering offloading pieces of your VoIP infrastructure, but want to see how that would unfold first. Where can you find this...
Consider the following integration scenarios: Moving medical records between EMR systems; financial information between banking systems; HR information between ERP systems; and software development information between SDLC tools. At first glance the approaches required for these integ...

Scaling things seems like such a simple task, doesn’t it? Open a new checkout line. Call a new teller to the front. Hire another person. But under the covers in technology land, where networking standards rule the roost, it really isn’t as simple as just adding another “X”. Oh, we tr...
At Plexxi we're building a simply better network for public and private cloud environments and next generation service providers. The next era of IT requires support for data center agility, scale-out applications, converged infrastructure, Big Data analytics and integrated security ov...
Network architectures are in the midst of a massive transformation. Not too long ago, traditional network designs began to strain under increased demand for compute and storage. This saw the advent of server and storage virtualization, giving organizations on-demand access to the resou...
At the heart of the Cloud Native model is a microservices application architecture, and applying this to a telco SDN scenario offers enormous opportunity for product innovation and competitive advantage. For example in the ETSI NFV Ecosystem white paper they describe one of the prod...
SDN / NFV may not be new with next gen telcos and data centers but by 2016 it is certainly going to be the new beast in DevOps space. It's a multi-million dollar virgin market, so it's not only those traditional OEMs are in the fray even the DB companies will be entering this new marke...
A major market for telcos will be the enterprise adoption of SDN. They will be able to harness the SDN/NFV innovations from the telco industry, and apply the technologies within their data centres, as well as using new telco services that they enable. As SearchDataCenter describes NFV...
Enterprise networks have become complex. They were designed and deployed to meet a specific set of business requirements at a specific point in time. Configuration modifications were rare, and manual or semi-automated processes together with strict change control procedures were enough...
Agema Systems, a provider of high performance Next-Gen Open Networking platform, invites network and virtualization professionals to attend Agema portfolio of 1G/10G/25G/40G and 100G product introduction at Cloud Expo® 2015, November 3-5 at the Santa Clara Convention Center. Agema wil...
For all the buzz-words and high-flying markets out there today, the truth of the matter is that at this point in time, IT is driven by speed. How fast can I spin up an image? How fast can I integrate the changes in my app? How fast can I test prior to deployment? How fast can I go from...
Over the last few years we’ve seen just about every part of the data centre move towards virtualization and software. First we virtualized desktops, then storage, then even our security tools. So when the idea of Software Defined Networking (SDN) started being floated around, it wasn’t...
Most of the time when we think about (and honestly, talk about) “programmability” of app services (in the network) we end up illustrating its potential by using load balancing or perhaps app security. That’s because the possibilities seem endless for those services, with countless exa...
"ProfitBricks was founded in 2010 and we are the painless cloud - and we are also the Infrastructure as a Service 2.0 company," noted Achim Weiss, Chief Executive Officer and Co-Founder of ProfitBricks, in this SYS-CON.tv interview at 16th Cloud Expo, held June 9-11, 2015, at the Javit...
If you’re curious about learning the difference between Software Defined Networking (SDN) and Network Function Virtualization (NFV) and how they relate, here’s a good article for you. I've written a quick summary.
In part 3 of our SDN series, I covered virtual versus physical infrastructure. This next segment will cover the three most commonly propounded benefits of SDN: efficiency, agility and security. Early, hyper-scale pioneers of SDN such as Google astounded the networking community with ...
For many MSPs, managing the outsourcing demands of their customers can result in a complicated relationship, but one that can be smoothed over by the MSP doing what’s right for them. Let me explain by example. I was in South Africa visiting a large MSP. They were using Entuity to m...
For some, SDN was about operational efficiency; about driving more stability and consistency out of the processes that push applications through the app deployment pipeline into production. For others, it was really about financial efficiency - the drive to lower capital expenditures. ...
SYS-CON Media announced today that Sematext launched a popular blog feed on DevOps Journal with over 6,000 story reads over the weekend. DevOps Journal is focused on this critical enterprise IT topic in the world of cloud computing. DevOps Journal brings valuable information to DevO...
SDN is a still simmering trend. It's not boiling over like cloud did in its early years but rather it's slowly, steadily continuing to move forward as more organizations evaluate, pilot and implement pockets of SDN within their organization. stage of sdn deployment 2015 But it's not ...
When the melting pot boils down to it, our network is its own culture, with recurring traffic patterns, similar end users, and equipment named after inside jokes only your company will understand. Just like living within your own culture, it's important to not only understand HOW patt...
It is possible to implement SDN solely using existing network infrastructure and to provide SDN overlay connectivity using tunneling technologies. That said, most people concede that some physical hardware will be needed to perform certain key network functions or at key locations wit...
SDN technologies are broadly split into two fundamentally different paradigms - "overlay" SDN and "underlay" SDN. With overlay SDN the SDN is implemented on top of an existing physical network. With underlay SDN, the fabric of the underlying network is reconfigured to provide the pat...
Imagine you are dropped off in the middle of a jungle, without any familiarity of what to eat, where to drink, or how to build a fire and shelter. Were you ready? Do you survive? In an environment that can, quite literally, eat you alive, it helps to be equipped with the right tools an...
In part 4 of our series on SDN, I discussed some of SDN's most commonly asserted benefits. Here I'll look at the drawbacks, the majority of which are organizational or financial and not technical. The most commonly cited reasons for actively not deploying SDN are: Staffing SDN r...
Infonetics analyst Clifford Grossner recently released a SDN enterprise study which found that nearly 80 percent of medium and large size businesses plan to implement SDN technology in the data center by 2017. The survey of 153 businesses also revealed that 65 percent of respondents ar...
TAPs and NPBs are certainly on a collision course and their functionality and use cases are overlapping more and more. Traditionally TAPs were relatively unintelligent - providing pass-through monitoring points (possibly with very limited filtering), passing a copy of the data seen on...
Polymorphism is a concept central to object-oriented programming. The notion of polymorphism is used to extend the capabilities of a basic object, like a mammal, to specific implementations, like cats or dogs or honey badgers, even though they don't care about such technical distinctio...

There’s a lot more happening on your network than you think, and it could be costing you real money. Like high blood pressure or cholesterol, operating your network beyond threshold, at capacity or with other unaddressed issues could be the silent killer for your enterprise. Advanced ...
One question that springs to mind is why invest in embedded physical SDN vSwitches which sit in-line between each and every appliance and their corresponding access ports? Why not simply apply the appropriate SDN configuration to the access switch on a per-port basis (assuming the acc...
Once at a trade show I was challenged by someone who used a low-priced SMB tool to monitor his network of about 50 devices. He insisted it could do everything Entuity could do, for example, it offered event management just like ours. Well…not quite. Lots of vendors offer event managem...
You may have noticed that we’ve been spending some time out west demonstrating our big data fabrics and sharing our vision for the third era of networking. You’ll be seeing more meet-ups and live demonstrations in the near future, so keep an eye on the blog and on Twitter to see where ...
