Did you know that you can develop for mainframes in Java? Or that the testing and deployment can be automated across mobile to mainframe? In his session at @DevOpsSummit at 20th Cloud Expo, Vaughn Marshall, Sr. Principal Product Owner at CA Technologies, will discuss and demo how inc...
While some vendors scramble to create and sell you a fancy solution for monitoring your spanking new Amazon Lambdas, hear how you can do it on the cheap using just built-in Java APIs yourself. By exploiting a little-known fact that Lambdas aren’t exactly single threaded, you can effect...
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...
The goal of Continuous Testing is to shift testing left to find defects earlier and release software faster. This can be achieved by integrating a set of open source functional and performance testing tools in the early stages of your software delivery lifecycle. There is one process ...
A lot has been written and discussed about Domain Name System (DNS) in the past few days. The DDoS attacks on one of the major managed DNS Providers a while ago just made us all take DNS issues seriously once again. So why so much emphasis on getting DNS Right? Like a lot of other peo...
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...
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...
Are you tired of slipping deadlines and missing commitments? Do you feel like the consistency of Software Testing is out of your control? Here is how to improve the predictability of software testing across multiple teams and projects. The foundation of enterprise software testing pre...
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...
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....
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...
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’...
If DevOps continues on the same trajectory into 2017 as it has been on for the past few years, specialized Ops teams could quickly become redundant. Instead, DevOps for digital companies will evolve to require only developers who nurture their own code into production. So how do establ...
Digital transformation is happening everywhere. It starts with an expectation that whatever an organization does in the real world is supported by—and expands through—its digital presence. As the process continues, digital transformation should drive innovative ways to engage customers...
Retailers are witnessing a rising trend towards customers ordering food online and requesting hybrid delivery, such as home delivery, picking up from stores or dedicated pickup points. In light of this and other emerging innovations, retailers need to develop and deploy new application...
Bimodal IT was initially defined by Gartner as, "The practice of managing two separate but coherent styles of work: one focused on predictability, the other on exploration." Of course this needs a little unpacking, but in essence Bimodal IT refers to the notion of two distinct areas...
Containerization is popularly viewed as the ‘virtualization of virtualization’ or ‘next generation virtualization.’ However, containers have existed long before virtualization or the advent of modern container technology like Docker and Linux Containers. Similar tech was built into mai...
One hour before March Madness is about to begin, the CBS Sports app crashes. Per Twitter, college basketball fans across the country are freaking out, trying to get their last minute bracket changes completed before the first game begins. Millions of fans around the world are expected...
To make sure we’re on the same page, let’s start by defining what we mean by a silo. “They are nothing more than barriers… between departments… causing people… to work against each other.” -Patrick Lencioni in 'Silos, Politics, and Turf Wars' Thanks to the work of Lencioni we ha...
Ask any IT person from the financial sector about SOX requirements and they’ll probably use some colorful language about how much time and money it sucks away. According to the 2016 Sarbanes-Oxley compliance survey by global consultant Protiviti, the average annual internal cost of SOX...
Few questions in software development are more divisive or tribal than choice of programming language. Software developers often identify strongly with their tools of choice, freely mixing objective facts with subjective preference. The last decade, however, has seen an explosion both...
Incident management is paramount to the success of any modern ITOps team. However, much like growing a business, scaling incident management can also trigger growing pains. As the landscape of devices, applications, and systems grows — each requiring monitoring — so too, does the alert...
If technical debt were like monetary debt, it would be hard to keep track of it unless you checked in manually. The only way many people find out their checking account is running out of funds is by logging in and checking the balance — or, worse, having a check bounce or a debit card ...
Functional monitoring is the process of looking at the functionality offered by a single application or by a distributed system. It aims at the process of assessing the availability and functionality of the use cases of the system. It checks that the system is capable of giving desired...
Pressure on application release cycles over the last few years has been steadily mounting. Thanks to increased demand for mobile computing applications, many organizations have significantly quickened the pace at which they develop custom applications. Looking over the horizon, however...
In his session at @DevOpsSummit at 20th Cloud Expo, Kelly Looney, director of DevOps consulting for Skytap, will will show how an incremental approach to introducing containers into complex, distributed applications results in modernization with less risk and more reward. He will share...
We’ve all been there. Some unexpected error pops up, and we’re frantically filling out a support ticket to figure out what went wrong as quickly as possible. As software delivery continues to increase in complexity, the role of technical support is becoming increasingly important to an...
Can a better UX simultaneously deliver a worse user experience? It sounds like a paradox, but it may be more common than you think. It describes a category of UX design practices that have little to do with improving the actual experience and everything to do with suggesting that the e...
DevOps has grown exponentially especially during the past 3 years, in facts its tentacles spreads beyond Dev and Ops but some organization's still see DevOps as an extension of Agile practice. It's because how as an organization perceive DevOps, while the scrum master's objective is t...
Functional testing is a type of software testing that evaluates the performance of individual functions of a software application. The purpose of functional testing is to ensure that the application and all of its individual functions work as they should in the real world and meet all ...
Here at PagerDuty, we spend a lot of time thinking about how we can help the DevOps community and IT professionals succeed. We’re particularly interested in the “hows and whys” of evolving DevOps practices, how to deliver value to our practitioners, and how to better serve the communit...
Fertile ideas that germinate out of internal collaboration are what will set your company ahead of the competition. The era of the open-plan office is over, but that doesn’t mean collaboration should go by the wayside at your firm. Rather, all professionals need to develop new ways to...
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....
Smart devices require smart monitoring. That’s not a platitude. It’s an imperative. In fact, the smarter the device, the smarter you need to be about monitoring it. As headlines have shown, unmonitored, unprotected smart devices may be a disaster (or a DDoS attack) just waiting to hap...
Thanks to the DevOps movement, we now understand why software delivery chains that consist of a series of silos are bad. They complicate communication between different teams, leading to delivery delays, backtracking, and bugs. When it comes to incident management, there is another ty...
How often is an environment unavailable due to factors within your project’s control? How often is an environment unavailable due to external factors? Are the software and hardware in an environment up to date with the target Production systems? How often do you have to resort to manua...
