Cisco has been ridding itself of consumer products for some time, which is why it was surprising to see Cisco at the International Consumer Electronics Show this year. According to CEO John Chambers, however, the new IoE (Internet of Everything) plan at Cisco is set to change the traje...
Sharing data is a cornerstone of the scientific method because it makes it possible to replicate work. That foundation is mostly absent from data science, which makes obtaining and reusing knowledge more difficult than it should be. Job postings for data scientists increased 15,000 pe...
If you listen to the persistent murmur in the market surrounding the Internet of Things right now, you'd believe that it's all about sensors. Sensors and big data. Sensors that monitor everything from entertainment habits to health status to more mundane environmental data about your h...
I like this word re-imagination from Mary Meeker’s Internet Trends presentation. We are seeing so many aspects of our life being transformed by the internet. Take for example, ordering a cab to go somewhere. Either we phone for a yellow cab here in California or if you are in New York...
We live in interesting times for sure. Who would have thought ten years ago that IBM and Apple would become partners? Here is the announcement as reported in eWeek: Apple and IBM surprised many on July 15, announcing a global partnership that will see the companies attempt to “transf...
A key development for the Internet of Things will be the evolution and emergence of the ‘Cloud Name System’, a directory system for Cloud applications in the same way DNS (Domain Name System) works for the web and email. Lori MacVittie wrote a while back about the need for an ‘SNS’ ...
When people talk about Big Data, the emphasis is usually on the Big. Certainly, Big Data applications are distributed largely because the size of the data on which computations are executed warrants more than a typical application can handle. But scaling the network that provides conne...
Do you avoid stores that have had a credit card breach? You are not alone. About 52% of people avoid merchants who have had a data breach according to a recent Lowcards survey. They surveyed over 400 random consumers to better understand the impact of identity theft on consumer behavi...
If you've had to test one of today's composite applications, you know that "access" has become one of the most daunting barriers to SDLC acceleration. Whether we're talking about access to dev/test environments or access to dependent applications, the ability to pull all the required p...
Much has been published about the Open Compute Project. Initiated by Facebook, it has become an industry effort focused on standardization of many parts and components in the datacenter. Initially focused on racks, power and server design, it has also added storage and now networking t...
Some people are never satisfied. These fearless agents of change are everywhere. They're informed, confident and willing to experiment. They seek out the best business technology solution for the job at hand. They act on instinct. Yes, you could say that they're driven. However, they'...
One of the primary principles of object-oriented programming (OOP) is encapsulation. Encapsulation is the way in which the state of an object is protected from manipulation in a way that is not consistent with the way the variable is intended to be manipulated. The variable (state) is ...
Last week Greg Ferro (@etherealmind) wrote this article about his experience with scripting as a method for network automation, with the ultimate conclusion that scripting does not scale. Early in my career I managed a small network that grew to be a IP over X.25 hub of Europe for a...
Cloud computing has finally come into its own. While we’ve been hearing for 8 years or more that cloud computing would one day take over the enterprise, the fact of the matter is that it’s been slow going. While the spread of cloud computing solutions hasn’t been as rapid as many earl...
It's an application world; a world that is rapidly expanding. With new opportunities and markets arising driven by mobility and the Internet of Things, it is only going to keep expanding as applications are deployed to provision, license, and manage the growing sensors and devices in t...
The other day I found myself in a discussion with a prospect regarding the merits of capturing complete stack traces for every transaction that flowed through their production system. You see AppDynamics doesn’t do that; we capture problematic business transactions, and this bloke seem...
Despite the hype and drama surrounding the HTTP 2.0 effort, the latest version of the ubiquitous HTTP protocol is not just a marketing term. It's a real, live IETF standard that is scheduled to "go live" in November (2014). And it changes everything. There are a lot of performanc...
We're launching the "Tap In Open Forum": a new series of blog posts where we detail a current topic being discussed in the software development and testing community and invite you to participate in an open discussion with our best and brightest here at Skytap. Feel free to share your ...
Since the birth of Hadoop in 2005-06, the way we think about storing and processing information has evolved considerably. The term “Big Data” has become synonymous with this evolution. But still, many of our customers continue to ask, “What is Big Data?”, “What are its use cases?”, and...
We often get asked “Should I use GridFS for file storage with MongoDB”. As with most things, the answer is a staunch “it depends”. GridFS looks like a great idea on paper - a virtual filesystem held within MongoDB which allows for larger than 16MB files to be held, synced and replicat...
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 ...
Good morning! Or evening, if you happen to be reading this on the other side of the world. Our topic for today is the internet. What? You already know about the internet? No, no, I don’t mean that internet, the boring old one you use to access YouTube and send Facebook updates, e...
I was recently reading Freakonomics’ authors Steven D. Levitt & Stephen J. Dubner’s latest book, Think Like a Freak, and passed over a quote that really resonated with me: So rather than address their root causes, we often spend billions of dollars treating the symptoms and are left t...
Accomplish much more, very rapidly, while spending less -- this is the business technology trend that savvy executives everywhere have embraced. Worldwide IT spending will reach a total $3.7 trillion in 2014, that's a 2.1 percent increase from last year, according to the latest global ...
This week in the States, the Nation celebrates it’s Independence and many people will be attending or setting off their own fireworks show. In Hawaii, fireworks are shot off more during New Year’s Eve than on July 4th and there is even Daytime Fireworks now. Cloud computing is explo...
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 ...
Software-defined architectures are critical for achieving the right mix of efficiency and scale needed to meet the challenges that will come with the Internet of Things If you've been living under a rock (or rack in the data center) you might not have noticed the explosive growth of...
As revenues from traditional voice and messaging channels continue to dwindle, operators are reassessing their role in the digital communication value chain, and defining what value they can bring to their customers. Of course "customers" increasingly includes partners as well as end ...
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...
Welcome to the fourth era of digital. The first three periods or ages or phases — call them what you like — were each defined clearly by transformative events. First, the dawn of the personal computer age in April 1977 with the debut of the Apple II (and validated in August 1981 with...
By now we’ve seen plenty of cost justification on the efficiency of using cloud infrastructure. You can easily Google “Cloud Computing Value” and get a stack of analyst and vendor reports. Or just pop open Amazon’s AWS value calculator and plug in some numbers. There are huge one-time ...
North Bridge in partnership with GigaOm Research released their 2014 Future of Cloud Computing – 4th Annual Survey Results. As you examine the 124 slides, one thing is obvious that the greatest growth in cloud computing is coming from Software-as-a-Service (SaaS). Market research like ...
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...
Anyone who has been involved with security knows there is a balance to providing both security and privacy and performance at the same time. Security is often blamed for performance woes, particularly when cryptography is involved. SSL and TLS have long addressed this balance by lev...
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...
When Instagram was sold to Facebook in 2012, it employed only 13 people and maintained over 4 billion photos shared by its 80 million registered users. Internally, Instagram was a small business. Externally, it was a web monster. Filling the gap between those two contradictory perspec...
This article defines long polling and presents a few techniques on how long polling could be used in Spring MVC web applications. Discussion covers both the AJAX and the server part of the solution as well as outlines a few possible options for implementation. The article compares perf...
