In a digital world that moves as fast as ours, programmers are applying new, creative ways of thinking to the software development process in a non-stop push for ever-faster turnaround times. In DevOps, Continuous Integration (CI) is increasingly the integration method of choice, in la...
Van Andel Institute has a 20-year legacy of biomedical research and scientific education with a focus on improving health and enhancing the lives of current and future generations. Formed in 1996 by Jay and Betty Ann Van Andel, the Grand Rapids, Michigan-based organization has evolved ...
What is DevOps? What are the universal principles of DevOps? How to you build a DevOps team? These are the kind of questions you often get asked when you're a self-professed DevOps enthusiast/evangelist/champion. And I know growing up we are taught there aren't any wrong questions, but...
It is ironic, but perhaps not unexpected, that many organizations who want the benefits of using an Agile approach to deliver software use a waterfall approach to adopting Agile practices: they form plans, they set milestones, and they measure progress by how many teams they have engag...
Growing a digital business is essential for virtually every enterprise across every industry. Large enterprises and small businesses alike are digitizing their internal and customer-facing processes and services to increase efficiency, scale their businesses, and collect meaningful dat...
With big corporations moving to the cloud for their computation needs, a new type of resource usage model has come up recently that is called Server-less Computing. Contrary to the meaning of the term “Serverless” in “Serverless Computing”, it does not mean that servers are not involve...
With 10 simultaneous tracks, keynotes, general sessions and targeted breakout classes, Cloud Expo and @ThingsExpo are two of the most important technology events of the year. Since its launch over eight years ago, Cloud Expo and @ThingsExpo have presented a rock star faculty as well as...
Imagine that you have hundreds of development, testing, and operations teams spread across the globe that rely on each other to execute software testing. You have 245 test environments and you release to pre-production several times a day and deploy to production once a week. How do yo...
IT organizations are relying more and more on using release orchestration tools instead of tracking their software releases using programs like Excel, Google Docs, and PowerPoint. Much of the popularity of release orchestrators can be attributed to their versatility — they’re extremely...
I was walking down the street in Toronto one morning juggling a large tray of Tim Horton's coffee. Standing at a busy corner, waiting for the walk signal, I overheard the following conversation: Woman: "I can't believe they delivered the new application with all those options. No one...
My wife and I have a fun dynamic: she approaches situations with surgical precision, while I tend to be more of an imprecise paintbrush. One day, she chastised me for cutting something with a butter knife and insisted that I should be using a paring knife instead. I argued that it wasn...
How can a dinosaur adapt to the modern world? Well, if your ‘dinosaur’ happens to be a mainframe environment, then we suggest you take a good long at DevOps. The next generation of application delivery and agile methodologies are illuminating the challenges and solutions mainframe engi...
Containerized software is riding a wave of growth, according to latest RightScale survey. At Sematext we see this growth trend via our Docker monitoring adoption and via Sematext Docker Agent popularity on Docker Hub, where it crossed 1M+ pulls line. This rapid rise of containers now ...
Without lifecycle traceability and visibility across the tool chain, stakeholders from Planning-to-Ops have limited insight and answers to who, what, when, why and how across the DevOps lifecycle. This impacts the ability to deliver high quality software at the needed velocity to drive...
When it comes to measuring the success of your DevOps rollout, it can be challenging to identify the right metrics that will provide intelligence while avoiding the trap of vanity metrics that indicate action—but not necessarily progress—towards the outcome you’re looking for. In my e...
Moore's Law, which states that processing speeds will double every two years as we cram more and more silicon transistors onto chips, has been faltering since the early 2000s when the law started to run up against fundamental limitations presented by the laws of thermodynamics. While t...
Does your team have a testing strategy? In 2017, I have a hard time imagining that wouldn't at least have some strategy, however rudimentary. Unlike a couple of decades ago, you hear less and less about people just changing code on the production server and hoping for the best. At t...
While the benefits are many, the DevOps journey for an established organization can be a long one filled with surprises and challenges. To avoid as many of both as possible, learning from those who have gone before you can help you apply best practices to ensure a smoother path to succ...
Speed has always been a major challenge in software development, as waterfall projects took up a significant amount of time to carry out due to lengthy operational and manual processes. Under this setup, you could expect your initiative to take months or even years to reach completion....
My son is 14 yrs old. I've been consistently trying to encourage him to do two things. One, think ahead to the next logical outcome and two, do it right the first time. When he helps with projects around the house, he has a tendency to get it to an "almost complete" state. For example,...
Put yourself in the shoes of Captain Edward Smith of the RMS Titanic, seconds after the iceberg was reported to him and seconds (there were 37 of them, reportedly) before he reacted. In this critical timeframe – this brief space of time when the inevitability of disaster became clear –...
Paul The Octopus was known as an animal oracle who could predict the result of a football match. He made accurate predictions for the matches played in the 2010 FIFA World Cup. What if a browser could do the same thing? What if it anticipated the next page that the user was going to vi...
Business is demanding better, faster delivery of value from IT so it can compete in a market that’s moving at breakneck speed. How can IT accelerate business outcomes if it’s taking nine months to complete projects? First and most important, align IT teams with business goals: acquire ...
Instead of trying to determine whether or not virtualization is a good general business practice, you need to ask yourself one simple question: Does it make sense for my business? The floodgates have officially opened. Businesses that were once reluctant to invest in the IoT are now wi...
Over the years, many enterprises have achieved tremendous cost reductions and management simplicity through virtualizing their IT infrastructure. According to Gartner, while some firms have virtualized over 90% of their servers, on an average, most firms have over 75% of their servers ...
Effective collaboration and communication are highly valued by the DevOps culture, and it's been like that for a reason. It is an industry where even departments within the same company tend to distrust one another, and where distributed offices full of crucial roles are the norm. Thus...
I’m told that it has been 21 years since Scrum became public when Jeff Sutherland and I presented it at an Object-Oriented Programming, Systems, Languages & Applications (OOPSLA) workshop in Austin, TX, in October of 1995. Time sure does fly. Things mature. I’m still in the same buildi...
Performance testing is a form of software testing that focuses on how a system running the system performs under a particular load. This is not about finding software bugs or defects. Performance testing measures according to benchmarks and standards. Performance testing should give de...
Try to remember something that happened on your last vacation. How long did it take you to recall? Now, try to remember it again. You were probably able to recall it faster the second time— but, why? This is because as soon as you recalled the event the first time, your brain saved the...
A common development challenge is accurately scoping the amount of effort required when creating new applications. This can occur when an application’s requirements are first being designed, or even before. Since one of the most frequently-overlooked capabilities of service virtualizat...
Wouldn’t it be great if there were tiny robots that kept track of what you were thinking, then helped you implement your plans automatically? Well, if you’re an admin responsible for monitoring infrastructure, they exist. They’re called chatbots, and they are the key to leveraging Chat...
The visual model to declarative metadata representation to immutable deployment vision is in essence what SD is all about. The secret to making this approach practical, and thus the key to understanding why SD approaches have become so prevalent, is the word immutable. Once we ge...
In DevOps, those who can’t keep pace are often left behind. For many people leading DevOps initiatives over the past few years, this led to a painful choice of leaving security by the wayside. Many Waterfall-native approaches to security could not keep pace with their new DevOps-native...
I recently had a conversation with Jennifer Lent from TechTarget. She’s a respected thinker in our field and covers major trends. We spoke about the emergence of BizDevOps and its implications for businesses. We tackled a number of topics. She wrote about our conversation in a recent a...
Automation, a key pillar of the DevOps movement, frees IT operations to focus on higher-levl work and collaborate with cross-functional teams. But what if your automation is so good that developers don’t need you anymore? Mike Gualtieri of Forrester Research coined the term NoOps in hi...
Imagine a world where product owners, Development, QA, IT Operations, and Infosec work together, not only to help each other, but also to ensure that the overall organization succeeds. By working toward a common goal, they enable the fast flow of planned work into production (e.g., per...
There’s a lot of buzz around the speed index metric, but what exactly is this metric and how is it calculated? Even more so, why do we need a new metric when there are so many already on the plate? This article gives you detailed answers to these questions. User expectations have chang...
Websites are no longer just simple HTML pages with static content—they’ve evolved into a dynamic interface with features and content that are updated regularly. Website administrators use different techniques to ensure the user is viewing the latest version of the page or content. When...
Poorly managed development projects are bound to crash eventually. It's likely happened to you a dozen of times already. While writing code can be a lot of fun, managing code and dependencies can quickly become a maze of its own when you're dealing with the continuous growth of your co...
Since the term "DevOps" was coined in Belgium back in 2009, it has been impossible to avoid the debate raging around it. While we have watched it gain hype and momentum, many articles have been written to describe what elements of a DevOps strategy are required for it to be successful....
