Cloud Sniff Test: Cutting through the jargon

by David Kang (Red Hat)

Cloud is not software, cloud is not hardware, cloud is not virtualization, and cloud is certainly not a panacea for broken IT. Cloud is an architecture: a set of fundamental tenets that have different implications at different levels of IT, from network, to hardware, to applications, and to the IT process itself. To say you have a cloud is to say that you have a cohesive architecture, technology set, and most importantly processes, that work towards a defined goal under a set of well-understood principals. Building your cloud is as much about defining your goals and governing principals as it is about investing in technology.

Building your cloud and consuming cloud services
Step one is defining your governing principals. This is a crucial step before embarking on your cloud journey as the policies and principals you define will help you navigate your journey through the rapidly expanding cloud ecosystem. This is also an opportunity to ask tough questions and examine what your principals and processes are, and why you have them. Process is ultimately about managing risk, so consider what risks are acceptable under your governance policies and weigh them against the potential benefits cloud can offer. Both Facebook and Google have adopted “deploy to production” models that seem to fly in the face of process conventions such as ITIL or RUP, yet somehow they seem to survive. The penalty for not doing this exercise is ballooning adoption costs, or failed rollouts all together.

A new view on migrations

by Larry Spangler (Red Hat)

The funny thing about people is that as much as we complain about how bad things are, there’s a natural resistance to actual change. More often than not, the changes we long for come with a good deal of anxiety and a great deal of process pain.

This week, we moved into our new space in the “Red Hat Tower” in downtown Raleigh. There was a lot of excitement leading up to this move – new offices, new space, new neighbors, new opportunities – a fresh start all around. But that was countered by an equal amount of uncertainty and anxiety – would we like the new space, would we be giving up amenities, would the new commutes be a hassle, how long would it take to be productive again?

To manage activation keys, log in to System Engine and hover over the “Systems” tab, and choose the “Activation Key” sub-tab. Click the “+ New Key” link and enter the name and environment, then click the “Save” button.

Updates to the Red Hat Enterprise Clustering and Storage Management course

by Wander Boessenkool (Red Hat)

With the release of the updated Red Hat Enterprise Clustering and Storage Management Course (RH436) for Red Hat Enterprise Linux 6 a couple of new subjects have been introduced, while others have been updated to reflect the changes in the Red Hat High-Availability Add-On moving from Red Hat Enterprise Linux 5 to Red Hat Enterprise Linux 6.

One of the most noticeable new subjects in this updated course is the inclusion of an introduction to highly available, distributed, scalable storage using Red Hat Storage Server. Other updates include the use of multipathed storage throughout the course, as well as coverage of the XFS® file system.

Guest Post: Sean Millichamp, Red Hat Certified Professional of the Year

by Sean Millichamp (Secure-24)

Being chosen as the worldwide Red Hat Certified Professional of the Year has been a bit surreal. It has been an incredible honor and fantastic experience, especially being at the Summit this year. One of the questions I have been asked over the past few weeks is, “Sean, how did you do it? How were YOU the one chosen as the RHCP of the year?” The easy answer is that I wrote an essay and they chose me. But I believe that the real answer at the heart of things is open source, the community and many years of experience.

My first introduction to Linux in 1993 with Yggdrasil LGX was a spectacular failure. I’d found Yggdrasil for $10 at a local computer expo and bought it because I thought it would be neat to learn something about Unix. It lasted maybe a week and then it was off my system and forgotten. I couldn’t get networking to work. I couldn’t get X-Windows to work. I barely knew how to list files in a directory. What went wrong? I could point to a lot of things but my main trouble was the lack of hardware support and my complete lack of Unix skills. In retrospect, the biggest failure was that I had no idea about the Linux community out there (and without an Internet connection, I had no way to access it).
