We all remember the game from our childhood where one person whispers a phrase to the person directly next to them, who in turn shares the phrase with the following person in line. This continues through a group of people until it makes its way back to the original source. The game wen...
When building large, cloud-based applications that operate at a high scale, it’s important to maintain a high availability and resilience to failures. In order to do that, you must be tolerant of failures, even in light of failures in other areas of your application. “Fly two mistakes...
If you work for a large company, you'll often look around and wonder if moving to a daily release cycle or automating deployments is even possible given the number of meetings and the amount of process your releases are subject to. Between the CAB meetings, the QA schedules, and the co...
With microservices, SOA and distributed architectures becoming more popular, it is becoming increasingly harder to keep track of where time is spent in a distributed application when trying to diagnose performance problems. Distributed tracing systems attempt to address this problem by...
WebSocket is effectively a persistent and fat pipe that is compatible with a standard web infrastructure; a "TCP for the Web." If you think of WebSocket in this light, there are other more hugely interesting applications of WebSocket than just simply sending data to a browser. In his ...
In 1999, a man named Eric S. Raymond published a book called, "The Cathedral and the Bazaar." In this book, he introduced a pithy phrase, "given enough eyeballs, all bugs are shallow," that he named Linus' Law after Linux creator Linus Torvalds. Raymond was calling out a dichotomy th...
I’m not going to start with a reminder of how important app performance is. Let’s just all agree we already know this as the first app economy axiom and get on with the post payload. Actually, I know this is true because I’ve watched a staggering increase in the past year in use of web...
If you pay any attention to modern software delivery conversations, it sometimes feels like you are being beaten over the head with a Continuous magic wand. Continuous Integration, Continuous Delivery, Continuous Deployment, Continuous Documentation, etc. The idea is so easy that it’s ...
Your business relies on your applications and your employees to stay in business. Whether you develop apps or manage business critical apps that help fuel your business, what happens when users experience sluggish performance? You and all technical teams across the organization – appli...
How is your DevOps transformation coming along? How do you measure Agility? Reliability? Efficiency? Quality? Success?! How do you optimize your processes? This morning on #c9d9 we talked about some of the metrics that matter for the different stakeholders throughout the software deliv...
CIOs and those charged with running IT Operations are challenged to deliver secure, audited, and reliable compute environments for the applications and data for the business. Behind the scenes these tasks are often accomplished by following onerous time-consuming processes and often th...
A few weeks ago my colleague PJ Hagerty wrote about driving your existing monolithic application toward a more modular design. This time around I'll dive a little bit deeper into its importance and the benefits of application modularization. One of the most important best practices i...
Continuous Delivery is a trend that is taking the software industry by storm, and Continuous Delivery Management (CDM) is a new approach to release management that provides both transparency and a governance structure to manage continuous delivery across a large software enterprise. CD...
Sensors and effectors of IoT are solving problems in new ways, but small businesses have been slow to join the quantified world. They’ll need information from IoT using applications as varied as the businesses themselves. In his session at @ThingsExpo, Roger Meike, Distinguished Engi...
As companies embark on a digital transformation to better serve their customers the challenge of managing the performance and satisfaction with each user becomes ever more critical to the success of the business. When we look at the breakout companies today like Uber, Airbnb, and Slack...
There is a large gap between the understanding of modern processes and technologies, and actually doing something with them. In the DevOps movement, many of the core functions have met wide adoption, such as orchestration, release automation, and analytics. But what have not been as wi...
The world of software testing has changed a lot in recent years, with an increasing number of organizations moving towards an Agile approach to software development. In an Agile world, teams are being asked to move faster - reducing the length of time to delivery while still continu...
DevOps is hot. Mobile is hot. This week we're thrilled to host 3 pioneers in modern software delivery on a special episode of #c9d9 to discuss DevOps for Mobile apps. Patrick Debois (who coined the term DevOps), Nassim Kammah from Etsy (one of the original Unicorns!), and Trent Peters...
We've said it on this blog before, and we'll repeat the same message: Solving a software engineering problem is simple physics. It takes a set amount of energy to move a project from point A to point B, and changing the process or path doesn't change the unavoidable fact that difficult...
It’s easy to understand the confusion that is caused when the terms Agile and DevOps start getting tossed around. Buzzword bingo, here we come. But these two terms are more than just marketing speak – they’re technical movements born out of the desire to deliver better software, collab...
xMatters, inc., has released its integration platform -- enhanced connectivity technology designed to help enterprises overcome key hurdles in DevOps adoption. xMatters' award-winning cloud platform accelerates business processes through intelligent communication. The technology pinpo...
DevOps.is.everywhere. Wait. Let me rephrase that. The phrase "DevOps" is ubiquitous in the global technology scene. It is nigh on impossible to have a chat with any technologist, or journalist for that matter, and not touch on the subject. "DevOps" is one of those buzzwords that nearly...
Network communications are a top priority for DevOps teams working in support of modern globally-distributed systems and microservices. But basic network interface statistics like received and sent traffic aren’t as useful as they once were because multiple microservices may share the ...
This blog post is inspired by my observations from the field, including real customers and real applications. Everybody knows the importance of using proper logic to synchronize data access across multiple threads, it is a very common question during technical interviews. The followin...
I’ve been spending nearly half my time in Philadelphia over the past while, and I just happened to have a spare Saturday yesterday, so I hightailed it downtown. I had two objectives – to explore the Museum of Art and to attend a Brahms concert by the Philadelphia Symphony Orchestra. On...
Super Bowl 50 is upon us and while millions tune in for the faceoff between the Broncos and Panthers this Sunday, software testers will hold their breaths as these same fans flock to promoted web and mobile applications in droves. To the players, Super Bowl Sunday presents two paths: ...
In today’s modern computing age, constant enhancements in software innovations are driving us closer to an era of software revolution. Perhaps in the distant future, that may be how the 21st century is remembered best. Among the popular software languages out there, however, Java conti...
You are standing in the wings of the stage, it’s opening night, the curtain has just been raised, you hear the “James: Knocks on door” sound effects, and all of your hard work merges into a single step as you open the fake stage door. This is how most companies feel before they endeav...

In the currently high-flying world of DevOps, automation is the king. We are "automating all of the things" at a pretty astounding rate, and it is increasing productivity by reducing the man-hours invested in repetitive work. All very cool, but there is a dark side to automation, and t...
Most of the Java developers I know don’t like JavaScript. Initially. They would give you different reasons why, but the real one is simple: too much to learn to make it work. For many Java developers creating the front end of a Web application in JavaScript is a chore to write and a bu...
