One of the benefits of SDN is centralized control. That is, there is a single repository containing the known current state of the entire network. It is this centralization that enables intelligent application of new policies to govern and control the network - from new routes to user ...
If LinkedIn profiles are any indication, User Experience (frequently shortened to UX) is the new orange. Indeed, across all manners of technology, there is an increasing focus on improving user experience. Driven in part by Apple’s success on the consumer side, it would appear that IT ...
In the video at this link and embedded below I provide some context on new approaches to data can enhance outcomes for public sector organizations, with a focus on real world use cases. I also mention key requirements which apply at most government organizations for their data and how ...
Inarguably one of the drivers of software-defined architectures (cloud, SDDC, and SDN) as well as movements like DevOps is the complexity inherent in today's data center networks. For years now we've added applications and services, and responded to new threats and requirements from th...
Some people believe good or bad things always happen in threes. I believe you will always be able to find three (and probably more) things that are good or bad and somewhat related, but sometimes I get surprised by the apparent coincidental appearance of several closely related “things...
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...
72%. That's an estimate of how much of the IT budget is allocated to simply keeping the lights on (a euphemism for everything from actually keeping the lights on to cooling, heating, power, maintenance, upgrades, and day to day operations) in the data center. In a recent Forrester Res...
Ask two politically opposed people in any given country about the causes of the country’s problems, and guess what? Each will give you an answer filtered through their world-view. Through what they know, and what they believe. That is not to say one is right and one is wrong, both simp...
The announcement this week that Facebook is acquiring Pryte should make operators sit up and take notice. The communications landscape is evolving at break neck speed and operators need to start shouting about where they can bring value, before they get drowned out by the noise. Beca...
About 8 years ago at my previous employer we started a project related to Autonomic Networking. Autonomic Networking is modeled after Autonomic Computing, an IBM initiative from the early 2000s, targeted at creating self managing computing elements. The network version intends to creat...
Experts say that cloud computing is disruptive and then continue on to discuss how the cloud quickly enables innovation while competition between cloud service providers drive costs down. Both of these scenarios are accurate, but the disruption from cloud has additional shockwaves that...
Internet usage is evolving, and so are the application scenarios for business technology. In the foreseeable future, desktop personal computers will produce a much smaller share of commercial internet protocol (IP) traffic. Mobile and portable devices -- other than PCs -- will drive th...
In December 2012, research firm Coleman Parkes released a landmark study about the business benefits of service virtualization. The findings were significant: 60% of the respondents indicated that unavailability of systems for testing routinely caused software projects to be delivered ...

Thanks for attending one of my recent DevOps talks over the past few weeks in our community!

It’s no secret that doing nothing is often considered a safe bet. The psychology behind inaction is well understood, particularly in the case of IT — the path of least disruption is usually maintaining the status quo rather than trying something new, But once in a while, a decision ...
There are two fairly recurrent memes in IT infrastructure: the There’s an API for that! theme, and the Out of box! theme. It is actually telling that both continue to get play in IT given that they represent polar opposites. Assuming that each has a value, when do you need something th...
A while ago I wrote a few articles describing the various tunnel protocols used for network virtualization between vSwitches on servers, and between vSwitches and physical network gateways. These are the mechanisms that construct overlay networks on top of a physical network. VMWare us...
In production support it is often hard to correlate what might be happening on local servers with what users are reportedly experiencing. In April, the developers for a Java application that handles electronic distribution of scanned mail and electronic faxes were receiving reports tha...
In February 2011, Vivek Kundra announced the “Cloud First” policy across the US Government. The directive, issued through the Office of Management and Budget, required agencies to give cloud technology first priority in developing IT projects. He also described cloud computing as a “10...
How many different solutions do you need in order to implement an enterprise quality mobile solution? I think this is a worthy question. In years past MEAP (mobile enterprise application platform) and MADP (mobile application development platform) vendors tried to cover all of your nee...
The Pew Research Center Internet Project, one of the current initiatives overseen by Pew Research, is attempting to mark the World Wide Web’s 25th anniversary with a thorough look at the Internet’s future. The most recent report is called the Internet of Things, a phrase for modern dev...
That thing, next to the other thing, talking to this thing needs something to make it interoperate properly. That’s the goal of the Industrial Internet Consortium (IIC) which hopes to establish common ways that machines share information and move data. IBM, Cisco, GE and AT&T have a...
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 ...
It's a great time to be in the business of delivering software. Today, every business needs to leverage software to differentiate its products or services. So, like it or not, every business is in the software business. This theme resonated at the SDLC Acceleration Summit that occurre...
One of the challenges in scaling modern data centers rises directly from an increase in network complexity over the past few years. We can argue why complexity has increased, but it's reasonable to say that scaling data centers means more boxes - more servers, more network gear, more m...
BriefingsDirect had an opportunity to uncover more about about such new, agile business services at the recent 2014 Ariba LIVE Conference in Las Vegas when we spoke to Erik Gershwind, President and CEO of MSC Industrial Supply in Melville, New York. MSC has been using the Ariba Networ...
It's a given, this year more CIOs will shift their focus from selective IT efficiency to overall IT effectiveness. In 2014 and beyond, enterprise IT leadership will be judged on their ability to meet the demands of tech-savvy Line of Business users.

This is the type of meani...
When people write about software-defined architectures being "disruptive" to the network they're doing a bit of a disservice to just how much change is occurring under the hood in the engine that drives today's businesses. The notion of separating control and data planes is superficial...
I have taught classes and half-day workshops on mobile and digital strategies in 17 different countries around the world in the past three years. Some of the most interesting discussions during these classes and workshops are around the following topics - the strategies behind the mobi...
The days of completely separate storage network technologies are quickly fading. It feels like it’s only a few years ago that Fiber Channel was the way to create large scale storage networks. Big honking storage devices on a separate network, connected to Fiber Channel switches, connec...
Senior executives at progressive companies have been on a mission -- they're raising the bar of expectations for leaders of their significant investment in business technologies. Providing reliable access to IT resources and reporting on system up-time objectives are unlikely to gain r...
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 ...
Conventional wisdom refers to DevOps as a strategy, an approach, or a movement as some call it. DevOps addresses the idea that Development and Operations need to be aligned well in an application lifecycle, work closely and collaboratively to eliminate inefficiency, reduce bottlenecks,...
A great article of future of cloud IDEs: The Cloud IDE and its impact on DevOps by Chris Riley (@HoardingInfo). The article makes a number of excellent points. Many developers will oppose the Cloud IDE without much consideration. These are all very good points. From my personal exper...
Programmability is in F5's DNA. Since 2001 when we introduced iControl SOAP to the more recent additions such as iRules and iCall. Even looking at our most recent acquisitions you can see the common theme: an architectural vision based on extensibility and programmability. BIG-IQ is ...
IP Multicast is one of those technologies that most everyone loves to hate. It’s almost the perfect example of how complicated we have made networking. Getting IP Multicast to run depends on several protocols that are all somewhat intertwined or dependent on each, their relationship so...
Pop quiz: Your development team is developing a new mobile application. Should they optimize it for use over a mobile network or over WiFi? Another way to ask that same question is, "Should they provide a great quality of experience for users over a mobile network or over WiFi? And y...
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 UK’s Digital Government program is such a great leadership example, because not only are they pioneering the G-Cloud store, a service catalogue for IaaS, PaaS and SaaS suppliers, but also they are defining ‘Agile Procurement’ practices too. Since the G-Cloud project was aligned un...
Technology shifts are creating a lot of chaos, including the way we use words. Cloud. SDN. Multi-tenant. Instances. They're all inter-related and seem to have different meanings depending on who's trying to sell you what today. That's more than a tad bit disconcerting, because you kno...
