We get quite caught up in high level architectures at times. It is good to read some posts that focus on design and implementation and the practicality of taking higher level architectures to reality. Two of Ivan’s posts caught my eye this week. In the first, he discusses the differenc...
The key message of my presentation was that DDN’s WOS leverages OCP to optimize efficiency for object storage, but at the same time enables the Open Compute Community to build scale-out and more efficient object storage. The NO-FS (no file system) architecture of WOS enables OCP hardwa...
It is time for the 2014 Winter Olympic games in Sochi Russia where competitors including some athletes come together in what has become a mix of sporting and entertainment engaging activities. Some of these activities including real Olympic game events are heavier on sports appeal, so...
I've been following SSL for a long, long time. Since before the turn of the century, in fact. I devised performance tests back in the day that, on at least one system (back when PCI was still the standard method of enabling SSL hardware acceleration) actually melted circuits on the hos...
There is no such thing as an information recession however there the realities of economic challenges in IT data centers also known as information factories. Likewise, people and data are living longer with increased dependency on information being available and reliable when needed. ...
CA Technologies says, “For DevOps to work correctly, it must be treated as a movement, not a market for a specific vendor’s products.” As Arlo Guthrie once sang, with three people it is an organization. But if we can find … Feb. 5, 2014 03:00 PM EST  Reads: 16,799
The biggest difference between high-performance teams and more average teams is that the high-performance group actually acts like a team. That statement is so obvious, I am going to let it stand on its own. If you look at most groups, they tend to act less like teams and more like...
Application development trends significantly impact the design of data center networks. Today there are two trends driving a variety of transformation in the network: API dominance and micro-architectures. Combined with a tendency for network operations to protect its critical infrastr...
Rather than talking about what others should do or consider for their data protection needs, for this post I wrote down some notes using my Livescribe about what I need and want for my environment. As part of walking the talk in future posts I'm going to expand a bit more on what I'm d...
As enterprises become familiar with SDN and its benefits, it should be no surprise that one of the most familiar names in enterprise data centers would offer up a solution designed to automate and speed the process of setting up and managing these new networks. That's ultimately the go...
This is the second of a three-part series (read part I here) about how vendors are keeping backup alive, however what they can and should do to shift and expand the conversation to data protection and related themes. Modernizing data protection and what to do about it Building off of...
2014 will likely be a year of dual business goals for forward-thinking senior executives. Responding to ongoing needs for business efficiency and growth, but also adapting to exploit a fundamentally different digital commerce paradigm. Commercial digitalization, based upon the latest ...
A newish trend is quietly (comparatively speaking) increasing across the Internets. The basic premise is that end-users aren't being charged for data traversing mobile networks when accessing certain sites, much in the manner users are not charged for calling a company's toll free (800...
To say that cloud security for cloud computing is gaining traction would be the understatement of our era. Whether in public clouds, private clouds, or hybrid scenarios – it seems like everyone is in the cloud. Healthcare providers, eCommerce, disaster recovery services, data storage...
We are a few short days away from the biggest spectacle in sports – the Super Bowl. It is impossible to avoid talk this week of Peyton Manning, the Denver Broncos, the Seattle Seahawks, and the NFL in general. But does the NFL have anything to teach tech industries? The NFL is a mas...
The coming “Internet of Many Different Things” is not a world that is still way out in the future. According to researchers, somewhere between 2008 and 2009 there were as many “things” connected to the Internet as the number of people on the planet – over 6 billion! According to GSMA...

#SDAS #SDDC A programmable platform should be more than just lipstick on a CLI

The term programmability is, like every other term associated with hype-driven trends, used to describe a wide range of capabilities. In general, when applied to "the network", programmability imp...

Until recently, when I would talk about "APIs", I would qualify it by saying "Web APIs", in order to distinguish from the older meaning of APIs as more the tightly-coupled APIs used in Java, C/C++, or even Visual Basic. If you just said "APIs", until recently, some people may think you...
Recent commentaries by cloud industry luminaries Reuven Cohen & Krishnan Subramanian address key issues related to relative importance and potential longevity of an independent Platform-as-a-Service (PaaS). In his commentary, Reuven poses, "Do consumers really care about the difference...
During a session at Gartner Data Center 2013 (Software Defined Networking? Not a Question of If, A Matter of When and How) the question of SDN adoption was asked by speakers Joe Skorupa and Andrew Lerner of an approximately 100 person audience. These are the (very informal and totally ...
Last week I walked through the packet formats for VXLAN and NVGRE specifically focused on ways by which the overlay packets provide information to the physical network that help the physical network. Some of the initial extreme thoughts that the overlay and physical network can and sho...
Companies are increasingly moving their data security to the cloud. By the 2015, 10% of overall IT security enterprise product capabilities will be delivered in the cloud, according to a study conducted by Gartner. In fact, the cloud data security market is expected to reach $4.2 billi...
Every recent major innovative change in networking has ultimately been about operational efficiencies; about people time and not product costs. Financially, IT is a study in capital versus operating expenditures. It's a study in short term versus long term; in product cost versus peo...
When we made our 2013 predictions for the realm of APIs, our premise was that API adoption and use was still a relatively nascent area, but one about to explode once smart people figured out its potential. We were certainly spot-on in that regard, but few believed us when we suggested ...
There is a question we need to ask. It is a question which might end up annoying some people in the Cloud industry however it is one which we need to ask. Was the Cloud designed to be this way? This is to say, was the Cloud designed as terminology meant to distract everyday consumers f...
There have been many articles describing overlay networks in the past few quarters. It's a relatively straightforward concept, not far removed from some of the older VPN technologies very popular a while ago. The actual transport of packets is probably the simplest, it is the control p...
Can we stop confusing these two, please? Kthanx. For some reason when you start applying "software" as a modifier to anything traditionally deployed as hardware folks start thinking that means that hardware is going away. Software-defined networking (SDN) is no exception. There's...
Welcome to the future where light bulbs suck power for WiFi even when they are switched off (as reported by Redmonk's Tom Raftery), where a smart thermostat company is bought for $3.2 billion, and where electric vehicles can take commands from your wristwatch. What does this all hav...
To lower IT operational costs and/or to become more agile, the business must simplify the processes to deliver and manage infrastructure and the applications running on that infrastructure. Focusing on one without the other is simply applying yet another band-aid to an already hampered...
If you happened to be in attendance at CES (Consumers Electronic Show) 2014 in Las Vegas, you might have picked up some information about the Internet of Things. It seems, to our ears, the Internet of Things has gone from a small and interesting topic of conversation at Cloud trade sho...
Over the past few weeks we’ve seen a wide array of predictions for what’s to come in 2014. Vendors, analysts and reporters alike have been guessing which companies will succeed, which technologies will falter and where the industry will stand a year from now. Despite all the different ...
The recent announcement of the open-sourcing of the Codebox IDE is a good excuse to take a break and examine some current cloud-based IDEs. If you’re new to the space, a cloud IDE lets developers code and manage their projects from a browser. This lets you keep all of your code in the...
For as long as I remember networking has struggled with the balance between aggregated and individual traffic flows. Following the abilities of the technology components we use, we have been forced to aggregate, only to be allowed to de-aggregate or skip aggregation when technology cau...
With SDN top of mind (or at least top of news feeds) of late, it's natural to wonder how F5's architecture, Synthesis, relates to SDN. You may recall that SDN -or something like it - was inevitable due to increasing pressure on IT to improve service velocity in the network to match th...
Cloud computing is great, right? As a way to get something up and running quickly, affordably, and with a minimum of fuss, it can rarely be beaten. But some of the most compelling attributes of the public cloud are best suited to ephemeral or (relatively!) short-term use cases. You can...
So I’ve been staring at this blinking cursor for the last 5 minutes wondering what story to tell. ‘Once upon a time, there was a….‘ No that won’t work. ‘It was a dark and dreary night as our protagonist grudgingly dragged his feet toward the impending…‘ No, not that either. How ab...
Why is it that the definition of SDN continues to get debated? I think the definition of SDN remains a bit squishy. And while I am not entirely certain that it matters (people shouldn’t be buying SDN; they should be building networks), it is an interesting phenomenon, and understand...
As we embrace 2014, it’s important to focus on emerging trends to predict any industry changes this year and in the coming years. Mike Bushong reviewed 2013 on the Plexxi blog and noted important events that will likely carry into this year, including how 2013 initiated SDN deployments...
That attackers are moving "up the stack", toward the application layer, should be no surprise. Increasingly, network layer attacks are a distraction; a means to engage security professionals attention while the real target - an application - is attacked. Even when this is not the case,...
From a news perspective, a year is defined by the stories that make headlines. But markets are frequently moved more by subtext than overt story. Its sometimes the less sexy and more subtle happenings at the fringe of media interest that determine how industries will evolve and ultimat...
