Java applications need a certain amount of RAM on a computer to run. Each time an object or variable is declared, it needs more RAM. Simply designating enough memory to hold every value declared and run each method would lead to a bloated application. To keep application memory requir...
Whenever I write about the cloud, I tend to break it down into three categories: software as a service (SaaS), infrastructure as a service (IaaS), and platform as a service (PaaS). As I was working on a cloud performance management ebook, a coworker suggested that I also include functi...

Imagine that you have hundreds of development, testing, and operations teams spread across the globe that rely on each other to execute software testing. You have 245 test environments and you release to pre-production several times a day and deploy to production once a week. How do yo...
The trend of treating infrastructure as code is growing in popularity and with good reason. Programmable infrastructure lets you take advantage of version control, continuous integration, and automated testing — practices that are proven to work for software development and that are es...
"We're no longer an airline. We're a software company with wings," claims Veresh Sita, CIO, Alaska Airlines. The success of today's businesses rests on software. It is an integral part of infrastructure, so we need to always ask, "How can it be better? More reliable? More secure?" Nat...

Lambda is the eleventh letter of the Greek alphabet, and it is also the name of the Amazon Web Services (AWS) service that lets you run code without actually configuring a server. Amazon chose the name Lambda because - well, okay, I have no idea. Comment here if you know. Thankfully, ...
Is your organization’s IT system operationally mature, and is it application-centric? In today’s digital landscape, achieving both of these are crucial for the success of any serious IT operation — both at the enterprise level and in the context of smaller organizations. What is opera...
Service providers have long been lauded for a willingness to ‘eat their own dog food,’ i.e. to use their own products or services for internal operations and/or development. For Catchpoint, that means that we use our own digital experience monitoring platform to ensure that the platfor...
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 and demo at @DevOpsSummit at 21st Cloud Expo, Dana Boudreau, a Senior Director at CA Technologies, will discuss how increasingly te...
A few years ago, if you would have asked me to define DevOps, my answer would have sounded something like “Mumble mumble automation, mumble, automation, mumble mumble, infrastructure-as-code, mumble mumble, strategy.” Thinking that DevOps equated to automation had mostly to do with the...
What is DevOps? What are the universal principles of DevOps? How to you build a DevOps team? These are the kind of questions you often get asked when you're a self-professed DevOps enthusiast/evangelist/champion. And I know growing up we are taught there aren't any wrong questions, but...
Technology has a well-deserved reputation for creating and then promoting digital trends, some of which are aligned to real change, while many are more hype than reality. A few examples of real trends that have shaped technology delivery over the past few years include the rise of Agil...
In the digital age, speed is everything and no-one wants to be left behind. Being slow to react is the first and, most likely, final nail in the coffin for a 21st century company. The rigidity of the traditional ‘waterfall’ development approach was overhauled by the ‘agile’ philosophy....
Digital transformation can be exciting, but it also can be painful. Organizations are trying to better support a growing mobile workforce that needs the flexibility to work from anywhere on any device. The ability to do so offers a distinct competitive advantage, as productivity soars....
Docker is on a roll. In the last few years, this container management service has become immensely popular in development, especially given the great fit with agile-based projects and continuous delivery. In this article, I want to take a brief look at how you can use Docker to acceler...
One of the core benefits of Java is the JVM, which is an out-of-the-box memory management. Essentially, we can create objects and the Java Garbage Collector will take care of allocating and freeing up memory for us. Nevertheless, memory leaks can still occur in Java applications. In ...
How important is data compression? The sharing of information in a fast and efficient manner has been an area of constant study and research. Companies like Google and Facebook have spent a lot of time and effort trying to develop faster and better compression algorithms. Compression a...
WAN infrastructures are highly persistent due to typically enormous investments in their dedicated hardware and management tools. WAN services like MPLS have undoubtedly been beneficial and enduring, but enterprises and IT departments require more flexible and economical solutions to p...
In everyday life, I find there are several parallels between day-to-day discussion and some of the lessons we can take from DevOps. Such a mindset can often bring a number of benefits to any business and often these eureka moments can grab you at unsuspecting times. For example, do yo...
Every company wants to see their company getting press and media attention. Unless it is due to a hacker and a security breach. Every few weeks you see in the media stories of companies who were hacked. Getting a new credit card every few months because the data was hacked has been rou...
Information Technology has advanced in different areas at different speeds. This has always been true, as people found workable solutions to the problems that faced them today, most often before there was a market for those solutions. While things like virtualization and eventually clo...
