Achieving the ultimate ‘Five Nines’ of web site availability (around 5 minutes of downtime a year) has been a goal of many organizations since the beginning of the internet era. There are several ways to accomplish this but essentially a few principles apply. Web applications come in ...
The focus of a BI professional in an organization is to help get the right information to the right decision makers at the right time. In modern times, Big Data analytics has been one of the primary sources of business intelligence acquisition. Tools like Hadoop have revolutionized the...
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,...
Some time ago I blogged that Java Swing should be deprecated and replaced with JavaFX. In this blog I’ll show a piece of JavaFX namely event handlers and binding. I’ve created a simple Sign In window with a GridPane layout (it’s JavaFX equivalent of Swing’s GridBagLayout). I’m not goin...
The Internet of Things (IoT) is a new hot buzzword and like most buzzwords, its purpose and definition are grossly misunderstood. When some people hear the term IoT they immediately associate it with a refrigerator reminding us to order milk or our Fitbit wearable device tweeting how w...
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...
One of the most powerful features of QuickBase is the ability to share data across applications within a QuickBase account. Many QuickBase application managers may be unaware of these features or may be unaware of how to best gain benefits and avoid some important associated risks, suc...
Logentries new Aggregated Live Tail provides effortless, real-time visibility that you cannot get anywhere else…and is a joy to use (and I cant say the same about carrying a cat by its tail – for so many reasons). For those of you not familiar with our existing Live Tail view, Aggrega...
Application delivery, as defined as its own little corner of the network industry, has been fairly focused on assuring the performance, security and availability of applications since its inception back around 2003. Oh, the ways in which those three core tenets have been supported by a...
It's not the first time we've heard the statement that cloud can be too expensive and I doubt it will be the last. This latest episode comes from Alexei Rodriguez, Head of Ops at Evernote by way of Structure 2014: It is important to note that this admission - like those in the past - ...
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...
There’s been a lot of talk recently about the “Internet of Things,” where all kinds of devices – everything from clothing to appliances to vehicles — will be interconnected via the cloud. Sounds enticing, but really not much of a stretch from what’s already happening now via smartph...
One would think that small businesses have things easy because fewer employees means a smaller and easier team to manage. In fact, there are a lot of challenges that are unique to small businesses, and one of the big ones if "growing pains." It's difficult for a business owner to lo...
Application delivery is always evolving. Initially, applications were delivered out of a physical data center, either dedicated raised floor at the corporate headquarters or from some leased space rented from one of the web hosting vendors during the late 1990’s to early 2000’s or some...
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...
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...
While working on the second edition for my Java 24-hour Trainer book I’m re-writing some of the code samples to use lambda expressions. Today I was re-writing an example for wait/notify for the chapter on multi-threading. Beside illustrating the wait/notify, I used a closure in this ex...
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...
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 ...
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 ...
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...
