I am not sure how many people remember Cisco SANTap. About ten years ago, Cisco introduced a data tapping mechanism in the MDS 9000 fibre channel switches. The idea was to allow the data path to be “tapped” at-will. Tapping in this case meant using a mechanism in the switch to split th...
Our guest on the podcast this week is Helen Beal, Head of DevOps at Ranger4 Limited. We discuss how successful DevOps transitions depend on culture, so to start companies must identify their current problem areas. Helen describes the most successful DevOps culture as a place where each...
Docker containerization is increasingly being used in production environments. How can these environments best be monitored? Monitoring Docker containers as if they are lightweight virtual machines (i.e., monitoring the host from within the container), with all the common metrics that ...
Early in my DevOps Journey, I was introduced to a book of great significance circulating within the Web Operations industry titled The Phoenix Project. (You can read our review of Gene’s book, if interested.) Written as a novel and loosely based on many of the same principles explore...
The pricing of tools or licenses for log aggregation can have a significant effect on organizational culture and the collaboration between Dev and Ops teams. Modern tools for log aggregation (of which Logentries is one example) can be hugely enabling for DevOps approaches to building...
Like me, you’re probably familiar with the story of the Pied Piper of Hamelin. A cautionary tale about the consequences of reneging on debt – it sure scared the crap out of me as a kid. In enterprise IT, we also accrue debt, but of the technical kind. While the results of non-payment ...
DevOps has traditionally played important roles in development and IT operations, but the practice is quickly becoming core to other business functions such as customer success, business intelligence, and marketing analytics. Modern marketers today are driven by data and rely on many ...
You can never be too careful. Security is on everyone’s mind. Not too long ago, we talked about how beefed up security impacts load testing and we want to continue the conversation. How do you keep yourself and your company safe in the age of industrial and state-sponsored hacking? In ...
Parasoft's business partner Skytap recently invited Wayne Ariola (Parasoft Chief Strategy Officer) to be a guest on their DevHops podcast. With Skytap's Noel Wurst moderating, Wayne and Skytap's Jason English chatted about continuous testing, service virtualization, and how SDLC accele...
Everyone loves to talk about DevOps, but when it comes to real life enterprise implementation, things start to get a little shaky. Having gone through the process with hundreds of organizations, the XebiaLabs Sale Engineering Team relayed to me the 6 most common mistakes they see when ...
I've been asked several times recently about the difference between Verification and Validation in automated testing and for some advice on applying and documenting each kind of testing. Let me first take a minute to define these terms. Verification is testing that your product meets ...
Listen closely to the background hum of any agile shop, and you'll likely hear this ongoing chant: Automate! Automate! Automate! While automation can be incredibly valuable to the agile process, there are some key things to keep in mind when it comes to automated performance testing. ...
The evolution of IT operations is upon us. There has been a lot of change in both direction and momentum over the last several years, and at this point, it is not hard to see the future of Ops. Perhaps, having worked for a networking firm and a server automation firm, it is easier to ...
Over the last few years we’ve seen just about every part of the data centre move towards virtualization and software. First we virtualized desktops, then storage, then even our security tools. So when the idea of Software Defined Networking (SDN) started being floated around, it wasn’t...
It’s a funny thing isn’t it? Vendors like to talk about so-called IT transformation in the context of the general move toward new mobile, digital, virtualized, cloud-centric initiatives that take us to the new style of IT we can achieve in the promised land. The trouble with media com...
When I started exploring virtualization, like many folks, I was in awe of how much efficiency came with moving physical servers into VMs. To this day, the number of success stories about improved usage, reduced overhead costs and increased functionality makes virtualization a solid bus...
Developers are – despite their attention to what is considered a very logic-based field of study – a very creative group. Give them a hurdle to overcome and they will. The problem, of course, is not that they’ve solved a problem, it’s that in doing so they’ve likely created a source of...
Have you ever considered including users in performance testing? It may not be the most obvious thing to think about, but the benefits are really interesting. There is nothing quite like the feedback that a real user provides, even for performance. In this blog post, we'll show you how...
Summary: As a Developer, you cannot attach the debugger to your application in Production, but you can use logging in a way that helps you easily diagnose problems in both development AND Production. You also get to make friends with Operations people – win! The applications we're dev...
Azure is Microsoft’s cloud computing platform, a growing collection of integrated services—analytics, computing, database, mobile, networking, storage, and web. In the 12 months since Build 2014, Microsoft has delivered over 500 new Azure services and features, and greatly expanded the...
DevOps has often been described in terms of CAMS: Culture, Automation, Measuring, Sharing. While we’ve seen a lot of focus on the “A” and even on the “M”, there are very few examples of why the “C" is equally important in the DevOps equation. In her session at @DevOps Summit, Lori Ma...
I can guarantee that if you are involved in recruiting new IT employees for your organization this year, then DevOps skills will be on your priority list. The problem is that I can also guarantee that many resumes and LinkedIn profiles will be awash with the word DevOps. After all, acc...
We really are moving in the direction of truly commoditized hardware. Some uses will always have specific requirements that are not mainstream and thus will require specialized builds, this is true in every industry. But increasingly, who made your hardware and where they got their par...
In the midst of Docker’s meteoric rise and the explosion of talk around containers, it can be easy to lose oneself in all of the new terminology and jargon. While we think about the challenges presented by using containers in production, we also continue to hear the metaphor of Pets vs...
Ten years ago, there may have been only a single application that talked directly to the database and spit out HTML; customer service, sales - most of the organizations I work with have been moving toward a design philosophy more like unix, where each application consists of a series o...
Beginning with Ruxit Agent v1.76, Ruxit real user monitoring evaluates the content sources of all browser-loaded content to determine if the content is “3rd party” content, “1st party” content, or CDN-delivered content. This valuable content distinction gives you greater insight into t...
Unless you fully automate infrastructure and platform provisioning, application build, test and deployment phases and have them working together in sequence, you can’t realize the ideal of continuous delivery. These ‘automation tool chains’ are a mandatory element of each DevOps enviro...
For being such a new industry there is a lot of video content based around DevOps. I found this out after trying to search for some entertaining or highly rated DevOps/IT videos on youtube. That process failed, so I decided to dig a littler deeper into the community to find some of the...
Our guest on the podcast this week is Alex Polvi, CEO at CoreOS. We discuss how CoreOS fundamentally improves the security of the internet by modeling the infrastructure best practices developed by Google, Facebook and Twitter. Alex also breaks down the specifications of CoreOS’ new in...
DevOps is all the rage these days and with good reason as it promises to reduce the time-to-market for new applications. It also promises to improve change management, allowing teams to deploy changes to their applications quickly and efficiently. However, DevOps isn’t something you bu...
It is interesting to me, how quickly the hype cycle of a good thing can turn it into a monster that will inevitably eat itself, leaving a much smaller – and much more useful – concept or toolset behind. It has happened over and over in high tech, one need only say “XML” to understand w...
Of the many additions to Java 8 such as the Stream API and lambdas, I noticed one of the lesser talked about ones was CompletableFutures. So I decided to have a play around with them on the last Java component I wrote. My use case in a nutshell was piping large volumes of data from a d...
“Today due to the nature of cloud services, solutions and integrations, APIs are the way to go because of so many reasons,” stated Ian Khan, Head of Innovation at Solgenia, in this exclusive Q&A with Conference Chair Roger Strukhoff. “I strongly believe that any company today that buil...
HP today announced the new HP ConvergedSystem 250-HC StoreVirtual, a hyper-converged infrastructure appliance. Designed to attract customers on a tight budget, the HP CS 250 includes a new three-node configuration that is up to 49 percent more cost effective than comparable configurat...
Microservices has the potential of significantly impacting the way in which developers create applications. It's possible to create applications using microservices faster and more efficiently than other technologies that are currently available. The problem is that many people are sus...
Most of the time when we think about (and honestly, talk about) “programmability” of app services (in the network) we end up illustrating its potential by using load balancing or perhaps app security. That’s because the possibilities seem endless for those services, with countless exa...
Recent unauthorized access to a U.S. government database led to thecompromise of information on at least 21.5 million individuals. This massive background investigation data breach also compromised usernames, passwords, mental health records and financial information. Although a securi...
It’s not hard to feel sorry for Chief Information Officers (CIOs) – the levels at which they need to operate change all the time… and depth and granularity of the dataflows that present themselves change all the time. Just when we thought we had the whole client-server model worked ou...
CoreOS, Inc. has launched Tectonic Preview, giving users easy access to Kubernetes 1.0, 24x7 enterprise-ready support, Kubernetes guides and Kubernetes training to help enterprises begin experiencing the power of Kubernetes, CoreOS and Docker. Together with the Tectonic Preview and 24x...
Stage setting: Camera is positioned above the treetop of one of three tall poplars. It looks down on the terrace of a pub. It’s evening, but there’s still enough light to see that the terrace is sparsely populated. Camera slowly moves down towards a specific table in the corner… As t...
