We’re going to explore high availability and load balancing using Keepalived and HAProxy. Together, Keepalived and HAProxy provide some unique benefits. Specifically, they provide a low cost solution for high availability compared to proprietary hardware-based load balancers.
It is easy to look at the unicorn companies of our world, most notably Netflix, and say, "That's it! That's how we should be doing it". Whether it's DevOps or Microservices, they seem to have it nailed. Most people assume that to get there is a matter of following a few simple steps an...

I talk a lot about SDAS (that's Software Defined Application Services) with respect to F5 Synthesis and, well, F5 in general. That's because what F5 Synthesis delivers the ability to easily provision and ...

I had the opportunity to present on Nov 5th at DevOps Summit by SYS-CON Events in Santa Clara, CA. Here are my slides. The world is Hybrid. Organizations adopting DevOps are building Delivery Pipelines leveraging environments that are complex – spread across hybrid cloud and physical ...
Let's face it, there's quite a bit of confusion around what constitutes an SDDC, not to mention how you go about building one. NIMBOXX recently created an awesome all-in-one SDDC Cheat Sheet to help you navigate this fast growing infrastructure. Whether you're looking to boost your ...

Software Defined Application Services (SDAS) are going hybrid. .

Organizations are turning to cloud not just as an option for applications but also for the network and application...

The Smart Home concept is a subset of the Internet of Things(IoT). The core idea is to connect “things” (digital devices) to each other to facilitate communication, feedback, and alerting. In essence connecting the physical world with the digital world. We are installing new sensors an...
In a perfect world, Application Performance Management (APM) has all the right elements in place, providing value to the business and IT by giving us the metrics we need and showing us the health of our applications. It alerts us to anomalies when slowdowns occur, and shows us trends ...
Docker has been quickly adopted by nearly everyone and incorporated into everything from cloud technologies, to continuous integration and build systems, to solo developers working exclusively on their laptop. Heck, even Microsoft is getting in on this! It was born in PaaS (dotCloud) a...
Demonstrating the value of any tool can be tricky. There’s no “12 Step Program” you can follow to guarantee success. It’s not like trying to quit smoking or lose weight. There’s proven data spread over years of research showing how to do those things. In this article I will talk about ...
In my previous article, I had introduced how DevOps can play a role in JVM troubleshooting. In this series, I would like to share a case study that we encountered in our organization and how we isolated the issue before engaging the right team to fix it. One of our customers upgrad...

We keep saying that, does it mean what you think it means?

Operationalization (which is really hard to say, go ahead - try it a few times) is a concept that crosses the lines between trends and technologies. Both SDN and DevOps share the notion of "opera...

You're in a quarterly meeting where everyone is armed with slide decks; some good, some mind numbingly bad. It's your turn, and you have a concise five-slide deck comprised of targeted, well designed, and insightful graphs. The graphs are clear and the room is able to discuss the highs...
Operationalization (which is really hard to say, go ahead - try it a few times) is a concept that crosses the lines between trends and technologies. Both SDN and DevOps share the notion of "operationalization" as a means to achieve the goal of aligning IT with business priorities, like...
Previously, we wrote about setting up a Windows environment to log JSON formatted logs using our Windows Agent or our DataHub. Now we'll tackle IIS. IIS, like Windows, has a unique log format that makes it difficult to read, parse, and garner useful information. The log is a flat fil...
You don't necessarily get 2x the value from your logs when your volumes double. Value is more aligned with the analysis and trends you can extract from your data. It's no secret that log data is quickly becoming one of the most valuable sources of information within organizations. The...
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 ...
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...
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...
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...
