The widespread success of cloud computing is driving the DevOps revolution in enterprise IT. Now as never before, development teams must communicate and collaborate in a dynamic, 24/7/365 environment. There is no time to wait for long development cycles that produce software that is ob...
Do you think development teams really update those BMC Remedy tickets with all the changes contained in a release? They don't. Most of them just "check the box" and move on. They rose a Risk Level that won't raise questions from the Change Control managers and they work around the...

You often hear the two titles of "DevOps" and "Immutable Infrastructure" used independently. In his session at DevOps Summit, John Willis, Technical Evangelist for Docker, will cover the union between the two topics and why this is important. He will cover an overview of Immutable In...
The stack is the hack, Jack. That's my takeaway from several events I attended over the past few weeks in Silicon Valley and Southeast Asia. I listened to and participated in discussions about everything from large datacenter management (think Facebook Open Compute) to enterprise-l...
Docker is an open platform for developers and sysadmins of distributed applications that enables them to build, ship, and run any app anywhere. Docker allows applications to run on any platform irrespective of what tools were used to build it making it easy to distribute, test, and run...

The integration between the 2 solutions is handled by a module provided by XebiaLabs that will ensure the containers are correctly defined in the XL Deloy repository based on the information managed by Puppet. It uses the REST API offered by the XL Deploy server: so the security permis...
I’m not going to explain the basics of microservices, as that’s that’s handled elsewhere. The pattern of using APIs, initially built to cross application boundaries within a single enterprise or organization, is now being leveraged within a single application architecture to deliver fu...
While the DevOps movement and associated technologies have garnered much attention and fanfare, few have addressed the core issue - the hand off from development to operations. We tend to not acknowledge the importance of Release Management - a critical DevOps function. Release Mana...
When OpenStack aficionados gather in Vancouver in a couple of weeks, one of the hot topics will be containers, a “new” alternative to virtualization. Actually, container technology has been around for a couple of decades, but it is trending among the IT community at a fever pitch these...
In this 4-part blog series, I am exposing DevOps best practices using a metaphor inspired by the famous 6th century Chinese manuscript: “The Art of War.” It is worth reminding that Sun Tzu, just like me, considered war as a necessary evil, which must be avoided whenever possible. What ...
It's a "given" in software development - release schedules always slip. Requirements shift, developers underestimate timelines, and quality assurance (QA) finds unexpected defects. Another law of software development is that final release dates are often inflexible. If a market or a ho...
Sites don’t perform at their peak without great performance testers, and it takes time and effort to acquire them. You want the best in the business, just like any other department at any other company. But what do they want? What will convince them to join your organization? This post...
It's not just apps that are decomposing, it's the network, too. The network is bifurcating. On the one side is rock solid reliability founded on the premise of permanence and infrequent change. On the other is flexibility borne of transience, immutability and rapid change. There are,...
Container technology is the killer app when it comes to building and running microservices architectures. There are a countless number of articles, events, and resources out there related to the hot topics of containers, microservices, and DevOps. Docker is a player in the container ma...
Andrew Phillips recently spoke on the topic of “Mindset, Tools, and Goals: From Continuous Delivery to Containers” where he answered the following questions: Why are we writing software in the first place? Relation to Continuous Delivery and Devops: need to have delivery to the use...

The Capability Maturity Model (CMM) has become an essential tool for assessing IT initiatives. Originally developed to assess the capabilities of government subcontractors in the 1990s, the CMM is now used by IT management to define best practices in a particular practice area. From ...
One of the best things about working here is the collaborative nature of our team. We throw around ideas, critique each other’s suggestions, and ultimately arrive at some pretty smart decisions through a combination of talking, illustrating, venting, analysis, logic, and insane amount ...
It was just two years ago, in March of 2013, that the PaaS company dotCloud decided to open-source its container technology under the name "Docker." Docker quickly became a hit, with Docker Meetups spawning weekly worldwide and downloads occurring at record-breaking rates. The dotCloud...

Lacking the traditional fanfare associated with any technology that can use the word "container" or mention "Docker" in its press release, Ubuntu Core and its new Snappy system management scheme was introduced late last year. Since then, it's been gaining steam with Microsoft and Amazo...
Containers and microservices have become topics of intense interest throughout the cloud developer and enterprise IT communities. Accordingly, attendees at the upcoming 16th Cloud Expo at the Javits Center in New York June 9-11 will find fresh new content in a new track called PaaS...
What’s hot in today’s cloud computing world? Containers are fast becoming a viable alternative to virtualization for the right use cases. But to understand why containers can be a better option, we need to first understand their origins. In basic terms, containers are application-cent...
I woke up this morning to the devastating news about the earthquake in Nepal. Sitting here in California that destruction is literally on the other side of the world but my mind immediately went to thinking about my good friend Jeremy Geelan. See Jeremy and his family have been l...
So I guess we’ve officially entered a new era of lean and mean. I say this with the announcement of Ubuntu Snappy Core, “designed for lightweight cloud container hosts running Docker and for smart devices,” according to Canonical. “Snappy Ubuntu Core is the smallest Ubuntu available...
