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....
Enterprise architects are increasingly adopting multi-cloud strategies as they seek to utilize existing data center assets, leverage the advantages of cloud computing and avoid cloud vendor lock-in. This requires a globally aware traffic management strategy that can monitor infrastruct...
Serverless is considered the successor to containers. And while it’s heavily promoted as the next great thing, it’s not the best fit for every use case. Understanding the pitfalls and disadvantages of serverless will make it much easier to identify use cases that are a good fit. This p...
While I am all for traditions like Thanksgiving turkey and Sunday afternoon football, holding onto traditions in your professional life can be career limiting. The awesome thing about careers in technology is that you constantly have to be on your front foot. Because when you’re not, s...
We talked a bit about the Software Development Life Cycle (SDLC) in a recent post, but today, we're going to dig a little deeper into one specific and crucial element in the testing phase, particularly for Agile development: regression testing. Regression testing refers to the process ...
I recently read something – a blog, a tweet, a LinkedIn article perhaps – describing the use of wire data to analyze application performance. I remember that the author’s use of the term “APM” in this context caused one reader to comment, complaining that “you can’t call wire data APM....
In large enterprises, environment provisioning and server provisioning account for a significant portion of the operations team's time. This often leaves users frustrated while they wait for these services. For instance, server provisioning can take several days and sometimes even week...
Today’s digital world has placed a premium on the user experience. Users have become incredibly demanding, willing and able to head to a competitor’s site if just three seconds of latency occur during their time on your site. Such high demand puts web performance at the forefront of yo...
Businesses are being driven up against the wall by continual industry disruption. Many are fighting back by adopting Lean as a means to support business transformation. The aim is simple: create more value for customers with fewer resources. Lean thinking views the whole, not its part...

Snowflakes are beautiful, unique creations. But, let's keep them in nature. They don't belong in our server infrastructure. Snowflake servers, where every configuration is just a little different, can introduce unnecessary security vulnerabilities and complications. While common in IT ...
The DevOps pipeline is constantly changing. Therefore relevant security controls must be applied contextually. We want to be secure, but I think all of us would rather spend our time developing and deploying software. Keeping up with server updates and all of the other security tasks ...
In the run up to our latest release of capabilities for developers, I sat down with David Yang, a senior engineer here at PagerDuty who’s seen our internal architecture evolve from a single monolithic codebase to dozens of microservices. He’s the technical lead for our Incident Managem...
We are experiencing a ‘crisis of engagement,’ according to a survey by management consultancy Gallup, with a staggering 87 percent of employees worldwide disengaged with their jobs. While there are many factors that can influence an employee’s contentment – from support to compensation...
That's not a fancy twist on a popular approach in IT. This post is about untangling the mess Agile Release Planning has become. We're living in an age where we're chasing the latest buzzwords and trends. We hardly slow down to look at the path we've covered to see if we've improved or...

Developing code, without considering either the current or future needs of the end user, can cause frustration and result in customer churn, which ultimately means lower revenues. In this blog, I'd like to describe something simple I came across that demonstrates how to avoid these pit...
Almost all of the luxury brands that we work with are somewhere on the long and winding road between multichannel and omnichannel. For outsiders, this seems to be a small step but in reality, this is an extremely complex transition. In the luxury industry, multichannel often means that...
After 15+ years of software development, I still use the words error and exception interchangeably. But is there a difference between exceptions and errors? I think it is best to make the distinction with some examples of errors vs exceptions. Let's use this example of a dishwasher....
We all know the story: a farm, a kid, a Commodore 64, and a modem maxing out at 300 bps. A few unexpected phone bills later, and young Ian Allison is figuring out how to game the system so he can keep using his newfound gateway to the world of tech. According to Ian, that is where he ...
The purpose of event management and monitoring is to make sense of events, and while this may require some analytics and intelligence, the goal is an actionable alert — a meaningful notification that enables the right person to take the right control action. So, we may leverage predict...
Exceptions are a type of error that occurs during the execution of an application. Errors are typically problems that are not expected. Whereas, exceptions are expected to happen within application code for various reasons. Applications use exception handling logic to explicitly handl...
There are some big red flags that signify your DevOps department needs an overhaul. Your deployment process seems to take forever. It only work from a few developers’ computers. It’s different for each server you deploy to. Sound familiar? Luckily the warning signs of a DevOps depar...
Waterfall analysis is a great tool for viewing detailed information about the various resources that comprise your user actions. When analyzing modern web applications, waterfall analysis can become quite complex and initially overwhelming. To make it easier for you to understand at a ...
Getting started is often the largest hurdle with any major project. Research, theory, and discussions are like the 30ft boat taking you and your team from the shore to a seemingly random point in the ocean where you will strap on your diving suit and plunge backward into the depths we’...
Even though DevOps has been around for a few years, it still is a fuzzy area for some organizations. A mashup of development and operations teams, DevOps centers on collaboration and a culture that seamlessly integrates developers and IT operations teams working to put out the best new...
