The following is an excerpt of a post originally published on June 29, 2012, on Vinny’s Tech Garage.
I’m really excited about CloudForms. In my recorded demo at Summit, I showed a RHEL 2-node active/passive cluster with GFS off an iSCSI target. Then I moved all the underlying CloudForms Cloud Engine components to shared storage. I was able to launch instances, fail over Cloud Engine, and see the correct status. After managing the instances, fail back, and all was good. All of this works because the RHEL HA cluster stops the databases and other services first, moves the floating ip over, then starts the services on the active node. This was a very basic deployment, much more could be explored with clustered PostgreSQL and sharded Mongo.

One of the core tenants of agile development is to focus on the tasks that are the highest priority and immediate need. This is sometimes referred to as “Just-in-Time” development. The idea is to focus on the tasks needed to ship the feature now and worry about everything else when it is actually needed. Another tenant that goes hand-in-hand with “Just-in-Time” is the idea of failing early. Basically, a team should know as early as possible if something is going to fail, that way the team does not waste time going down the wrong path. This means the team should develop a feature and solicit feedback in short cycles, allowing the team to quickly understand what works and what does not.

It has been a little over a year since Quint Van Deman was named 2011’s worldwide Red Hat Certified Professional of the Year. Out of 600 submissions, Van Deman, an RHCA and director of open source consulting at Emergent, stood out with his experience helping clients move from last-generation, proprietary IT infrastructures to next-generation architecture that embraces the synergy of open source, open standards and cloud-based solutions. With the next winner set to be awarded on June 28 at Red Hat Summit in Boston, we wanted to catch up with Quint to hear the story that won the title, what he’s working on now and how his past year has been.
So, what story did you submit to win the award?
What I really wrote about was my journey to becoming an RHCA and how that really benefitted my professional endeavors. The journey to becoming an RHCA really exposes one to the breadth of solutions that are out there in the Red Hat stack, and how those solve organizational challenges. I was very clearly able to take some of those direct lessons and apply them out into my work. Also, how the RHCA really provides what I call the ‘instant badge of credibility’ when I walk in somewhere. A lot of time when you go into an organization as a consultant, there’s a lot of what I call ‘technical chest-bumping,’ where there will be someone in the room whose only objective of the meeting is to prove that they are smarter than you. Having that RHCA up there really defers a lot of that, especially with folks in the room that may have taken a Red Hat exam.

Open Source is not only a business model for Red Hat; it’s ingrained into the DNA of the company. Because of this, Red Hatters can generally count on their co-workers understanding both the fundamentals of open source, as well as the ethos and methodologies that go with it. However, within Red Hat Services, the consulting teams often get customer questions around these topics, or hear from employees of our customers who relay things they’ve heard regarding adoption of open source within their enterprise.
So, with apologies to David Letterman, I’d like to share the Top 10 Signs Your Enterprise Doesn’t ‘Get’ Open Source. While this is meant to be a somewhat humorous look at the topic, I also think it’s an informative way to talk about improving an enterprise’s effective use of open source technologies and methodologies. I’ll break down the list not by rank order, but by three areas that customers typically encounter when dealing with open source: Consumption, Collaboration, and Creation. I’ll also put in a few thoughts about how to address each of these from an improvement perspective.

Who is getting trained these days?
The majority of my (personal) sector is government related. With the government mandating certifications for a lot of their contractors, that sector – federal contractors, federal government – is really making the investment and spending money on training. That’s not to say private industry is not doing it. To me, the federal sector are the ones driving the need where professionals must have to maintain those levels of certifications to stay in those contracts, and are putting a lot more emphasis on training.

Innovate or die. It’s the essence of what successful companies do, especially in the tech space. At Red Hat, there is ongoing innovation in every dimension of the business, with new products like CloudForms, new infrastructure like the Customer Portal and new metrics like Net Promoter.
The Curriculum team is similarly pushing to innovate with our course offerings and course delivery. In the last year we’ve completely changed the way Red Hat courses are taught to ensure the most hands-on experience possible. Gone are hour long, death-by-slide lectures. Students are actively engaged through multiple teaching approaches and near-continuous labs focused on solving problems rather than tools and technologies. Instructors are now armed with comprehensive guides with best practices on how to teach topics, resulting in across-the-board consistency and a more optimal student learning environment.

Drift is the unplanned or unintended changes that occur on a resource’s configuration. System administrators need the ability to track drift in their data centers to improve availability and reliability of their platforms, servers and applications.
Drift monitoring is a new feature in the latest version of the JBoss Operations Network 3.0 (JON). You can define a drift detection definition on the Drift page of a resource. Click the New button, assign your drift definition a name, a base directory, then select the files and/or folders to be monitored for drift. Wait a few minutes and JON will take the initial snapshot (snapshot 0) of your monitored files. Each time drift is detected, JON takes a new snapshot of the monitored files. Each snapshot has a number, and snapshots can be viewed in an intuitive, new view known as the snapshot carousel by double-clicking on the drift definition from the Drift page of the resource.
