Although the concepts of continuous delivery are well known, organizations with existing applications looking to implement CD still have a lot to consider. Customer demands aren't the only thing pushing development and operations teams into more frequent software releases. It is also ...
I've been super honoured to give an ignite talk during DevOps Days Vancouver 2014. Ignite talks are intense, as the slides mercilessly fly-by every 15 seconds, and this for 5 minutes sharp (yes, that's just 20 slides!). In this talk, I tried to present some of the lessons we've lear...
It does not take much to understand the benefits of the DevOps culture, processes, and tools. However, implementing DevOps in your organization is not as obvious and usually involves more than simply setting up tools. You have to convince team members, map old processes to new, and ma...
Microservice architectures are the new hotness, even though they aren't really all that different (in principle) from the paradigm described by SOA (which is dead, or not dead, depending on whom you ask). One of the things this decompositional approach to application architecture does...
At first glance, it might seem that the goals of DevOps and regulatory compliance are inherently at odds. Whereas much of the buzz around DevOps advocates delivering software at dizzying rates, compliance and security are concerned with proper oversight of the change management process...
Considered by many as the next step beyond Agile, DevOps has proven to be effective at accelerating development cycles, improving performance, reducing bugs and overall improving the innovation and velocity of development teams. There are a couple ways to look at DevOps: first, DevOps...
Organizations are turning to cloud not just as an option for applications but also for the network and application services that deliver applications to anyone, anywhere at any time. And not just "in" the cloud marketplace, available for immediate provisioning and deployment, but as pa...
We have built our new Community Pack technology as a way for small or large communities to share methods to extract the important information generated by their systems and technology.
Since the announcement of Docker approximately 18 months ago there has been an explosion of new technology in this space. Although the list is becoming very long, here I will outline five evolving Docker-related technologies that are driving the direction that cloud technology is going...
We love hackday here at PagerDuty – it’s a great opportunity for everyone at the company to work on projects they’re passionate about, get the creative juices flowing, and see how we can mix up the tools and technologies we know to help out our users and each other. Last month was one ...
The annual G20 summit, held this year in Brisbane, Australia, has concluded. It follows by a week the conclusion of the 15th Cloud Expo and 3rd @ThingsExpo in Santa Clara, CA. I could argue that the latter events are more significant than the G20 summit. To be sure, there is no...
It may not seem like much. After all, it’s only 160 words on a webpage. But we believe that clearly stating our position on social media harassment and putting a process in place to respond to it will help us reduce and prevent it over time. For one, it’s a tangible way of promoting th...
JSON, short for JavaScript Object Notation, continues to gain momentum in our increasingly connected world. Reading this primer will give you a baseline understanding so you can start having intelligent conversations about the pros and cons of using JSON with your team. Contrary to it...
As we look at enterprises adopting DevOps (yes, enterprises are adopting DevOps, in droves), the question regarding outsourcing always comes up. Many (read: most) enterprises have at least some of their application delivery or IT operations outsourced to an external vendor. This may be...
Putting on a rock show is like piloting the Millenium Falcon – it’s simultaneously the fastest ship in the galaxy while being a “piece of junk.” The stage lights are so hot you start to sweat immediately, hoping those Jager-bombs are escaping through your pores and delaying the impend...
This year like last year, XebiaLabs polled Fortune 1000 companies in banking, manufacturing, healthcare, government and IT, interviewing DevOps teams and everyone from QA to C-level suites. More than 1,000 people were asked to share their perspectives on software delivery trends. Last...
The Internet of Things is only going to make that even more challenging as businesses turn to new business models and services fueled by a converging digital-physical world. Applications, whether focused on licensing, provisioning, managing or storing data for these "things" will incre...
On Halloween day, let's take a quick look at some of the top things that are killing software testers... Accelerated Release Cycles In response to today's demand for speed and "Continuous Everything," the software delivery conveyer belt keeps moving faster and faster. Considering ...
I am starting to get annoyed with the direction of all the DevOps discussions that fly across my Twitter feed each day. News Flash! Culture change is nothing new in the enterprise. Check out my latest rant at the virtulaizationpractice where I discuss how we over emphasize cultur...
Before YARN there was another resource negotiator, Mesos. Mesos was originally documented in a research paper, followed by an Apache project, and now commercialized as Mesosphere – who are building out an ecosystem around Mesos.
In a recent post I posted on DevOps.com, I suggested the term DevOps as a Service (DaaS). Personally I am not a fan of the term. Mainly because DevOps is not a ‘Service’. It is an approach to achieve business objectives by adopting a set of capabilities, namely: Continuous Business Pla...
Application Performance Management (APM) has been bred with all the right elements to give us the insights we need to see the health of our applications. Similar to your most trusted watch dog, it alerts us to anomalies when events occur, providing awareness to the environment that onl...
In my recent article, “Software Quality Metrics for your Continuous Delivery Pipeline – Part III – Logging,” I wrote about the good parts and the not-so-good parts of logging and concluded that logging usually fails to deliver what it is so often mistakenly used for: as a mechanism for...
DevOps is no longer considered a fad by those working with the latest development tools. Now, DevOps emphasizes people and processes as much as the cool tools, and there are many different approaches to bringing them together. If you Google search for “DevOps flow,” you will find lots...
The move to DevOps introduces additional constraints to the Iron Polygon, as individual projects become less distinct. In an environment focused on continuous automated testing as well as continuous integration and deployment, individual iterations become the project unit as organizati...
Can a postmortem review help foster a curiosity for innovative possibilities to make application performance better? Blue-sky thinkers may not want to deal with the myriad of details on how to manage the events being generated operationally, but could learn something from this exercise...
If you work in technology, you’d have to have been under a rock to have not heard about Docker. In a nutshell, Docker provides a lightweight container for code that can be installed onto a Linux system, providing both an execution environment for applications and partitioning to secure...
I just read through “The New Kingmakers,” a thought-provoking book by Stephen O'Grady of the small, but influential, analyst firm Redmonk. The thesis of the book is straightforward: technology changes have moved developers, previously of little importance within the world of IT, to a c...
Consider that the Age of the Cloud has precipitated a new agent concept which is lightweight, deploys quickly, and goes in virtually undetected with zero configuration. These agents are built with a survival mode in mind including a self-healing option for hands-free maintenance. At t...
The traditional approach to application delivery – do one big revision or introduce a major new feature over a short period – is rapidly being replaced by a new, faster and smarter approach, Continuous Delivery (CD). The core idea of CD is to create a repeatable, reliable and increment...
One of the more popular methods of dealing with not just with the explosion of devices but the growing challenge of dealing with growth of compute devices under management in general is virtual desktop infrastructure (VDI). While VDI has been overshadowed of late by newer and shinier T...
Now while we kidding around about naming this wall the "MacVittie-Roberts wall of DOOM", we weren't kidding about the need for better performance monitoring in production. After all, to definitely say that application performance is faster requires that we've measured performance after...
Cloud computing in the form of Infrastructure-as-a-Service (IaaS) has revolutionized the expectations of IT. Infrastructure that used to take weeks to months to provision is now available in minutes. Moreover, most of the traditional drawbacks associated with infrastructure have disap...

Applications typically log additional data such as exceptions to different data sources. Windows event logs, local files, and SQL databases are most commonly used in production. New applications can take advantage of leveraging big data instead of individual files or SQL. One of the...

Kirk Byers at SDN Central writes frequently on the topic of DevOps as it relates (and applies) to the network and recently introduced a list of seven DevOps principles that are applicable in an article entitled, "DevOps and the Chaos Monkey. " On this list is the notion of reducing var...
With the growing number of CSS Preprocessors like LESS, Sass, Turbine, Stylus and Swith CSS to name a few, it’s hard to decide which to choose for your project, and which will provide the best CSS authoring. Rather than focus on evaluating every CSS Preprocessor (that would simply take...

Unless you have been living under a rock the last year, you have probably heard about Docker. Docker describes itself as an open platform for distributed applications for developers and sysadmins. That sounds great, but why does it matter? Wait, virtualization isn’t new!? Virt...

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...
Isn’t it great to treat your girlfriend by cooking her favorite omelet every morning? In theory, sure, but in reality, chances are most of the time you end up with darn scrambled eggs instead. Let’s face it: you’re a great boyfriend but a terrible cook. Believe it or not, this is quite...
Enterprise applications are increasing in complexity, with multi-tier and distributed applications being the new standards for dealing with high-volume, high-scale requirements. In many development environments, the ideal scenario is to enable DevOps teams to manage dev/test environmen...
