Open source software – software freely shared with the world at large – is an old idea, dating back to the 1980s when Richard Stillman started preaching the gospel calling it free software. Then Linus Torvalds started working on Linux in the early 1990s. Today, Linux runs our lives. Th...
Redis is not only the fastest database, but it has become the most popular among the new wave of applications running in containers. Redis speeds up just about every data interaction between your users or operational systems. In his session at 17th Cloud Expo, Dave Nielsen, Developer...
One cloud does not fit all organizations. That's true whether it is a public or private cloud. A hybrid cloud option allows your business to create a custom solution that fits your organizational needs. However, there are always questions with new solutions. We reached out to indust...
About six years ago, Netflix began the move from a monolithic to cloud-based microservices architecture, openly documenting the journey along the way. Netflix is one of the earliest adopters of microservices, a term that didn't even exist when Netflix began moving away from its monolit...
Using any programming framework to the fullest extent possible first requires an understanding of advanced software architecture concepts. While writing a little client-side JavaScript does not necessarily require as much consideration when designing a scalable software architecture, t...
Test-driven development (TDD) has been around for a while now. Behavior-driven development (BDD), a comparably recent methodology, emerged from the practice of TDD and could reasonably be called a narrower application of TDD. The TDD process allows a developer to use a failing unit t...
This is the first DevOps book that shows a realistic and achievable view of the full implementation of DevOps. Most of the books and other literature I have read on DevOps are all about the culture, the attitudes, how it relates to Agile and Lean practices, and a high level view of mic...
Developers generally like to share their code, and many of them do so by open sourcing it on GitHub, a social code hosting and collaboration service. Many companies also use GitHub as a convenient place to host both private and public code repositories by creating GitHub organizations ...
Leaving aside (most of) the deeper technical details of the situation, an interesting development occurred in the open source community this week. Under the auspices of The Linux Foundation, a new ‘neutral’ coding community emerged as a result of the coming together of the Node.js and...
It is no surprise that OpenStack has evolved into a widely adopted cloud management framework. As it hurtles on a trajectory of rapid growth, a new breed of demands are making themselves felt – demands that a mature platform of this nature and scope must satisfy. One such requirement i...
The combined notions of open source and the ‘community contribution’ model of collaborative software application development are, of course, not new. The history of open source is actually traced back to early software exchanges between universities driven by academic principles of kn...
If you’re running Big Data applications, you’re going to want to look at some kind of distributed processing system. Hadoop is one of the best-known clustering systems, but how are you going to process all your data in a reasonable time frame? MapReduce has become a standard, perhaps ...
Opinions on how best to package and deliver applications are legion and, like many other aspects of the software world, are subject to recurring trend cycles. On the server-side, the current favorite is container delivery: a “full stack” approach in which your application and everythin...
“Life,” according to a saying often attributed to John Lennon, “is what happens to you while you’re busy making other plans.” Nowhere is this truer than in IT – especially in the world of ops. Operations staffs spend much of their time firefighting infrastructure emergencies. These un...
You don't have to look far to see evidence of open source software's impact on IT as a whole. It starts with large open source projects like OpenStack, Cloud Foundry, and Hadoop and continues to smaller but widely deployed components like OpenSSL and MySQL. I know what you're thinki...
When virtualization took the data center, it offered huge cost savings for IT ops and zero migration pain for developers. Coming at a time when IT was being pressed by the business for savings, vSphere took the data center by storm. This example is instructive when trying to conside...
I was experimenting with Java HashSet, which is a pretty expensive collection to create, but it has a benefit of the O(1) performance on the retrieval of elements from this collection. Based on my experiments performance of HashSet is improved over the last year. I’ve written a small ...
When I started exploring virtualization, like many folks, I was in awe of how much efficiency came with moving physical servers into VMs. To this day, the number of success stories about improved usage, reduced overhead costs and increased functionality makes virtualization a solid bus...
All enterprises, be they large or small, national or multinational, commercial or government agency, American or Chinese, Japanese or European, are carrying the dead weight of their history and almost certainly continuing to add unnecessary complexity and excessive cost that will progr...
Picking up a newspaper and turning on the TV, one is instantly confronted with news of yet another cyber hack. With cyber attacks headlining the news, millions of people are concerned with whether their personal information has been breached. These attacks are becoming more and more so...

It’s time to talk more vociferously about open data. A better headline for this piece would be: why open data is not an overnight sensation or indeed a turn of a dial or a flick of a switch, i.e., it is not something automatically achieved without some kind of longer term strategic dr...
Knowledge management, in business terms, refers to saving, developing, sharing, and effectively using knowledge for the benefit of organization. It refers to a multi-disciplined approach of achieving organizational objectives by making the best use of knowledge. Scientia potentia est ...
