OpenShift is great! Developers can quickly start development on a new project. Just log into the web console, create a new application, select a gear and start coding. When you are done implementing a feature you push to OpenShift and after a few seconds you can admire and share your work with the whole world.
But there is more to consider when working with OpenShift. What if you develop in teams? Usually applications are not directly deployed into production. How can I implement a staging process harnessing the OpenShift Infrastructure? How do I know if my changes passed an Acceptance Test or failed it? How does a test team know which features have been implemented?
The answer to these questions are usually not easy, and every company has implemented their own set of processes to address these problems. Although some Organizations have automated some of their IT Infrastructure, there are still a lot of manual processes and changes involved when it comes down to taking a particular software release from development into production. On the other hand, the business stakeholders have a high interest into a fast and efficient Release process, because every day that my feature is not in production and available to my users, is lowering my ROI.

Long an acquaintance and ally of government institutions, open source is no longer considered rocket science by the enterprise.
Companies find open source attractive because they’re not tied to one vendor, can make improvements in the system at any time and realize cost savings, all helping boost market penetration. And, of course, there’s the benefit of communities continuously improving the products.
In the outside world, governments are strong sponsors of this type of initiative, especially in Brazil, where the use of free and open source software is encouraged to make the market more democratic. And, of course, the market has become increasingly more open to open source. While there were once concerns about the reliability, security, and functionality, those fears are all gone. Red Hat has made it possible to combine the benefits of these technologies with the necessary support for mission-critical environments, developing platforms and the specific demands organizations face.

My interest in Linux started in 2005 at the age of 15 when I discovered Ubuntu Linux. After being upset about my slow and always virus-attacked computer, I decided to try out something completely new.
I never had Linux on my computer before and wanted to have a look at it. After some first trials with OpenSuSE I got into Ubuntu and made my first experiences with the open operating system.
After exclusively using Ubuntu for almost two years I had a look at several other distros, including Debian, CentOS and Fedora. To learn more about Linux I built my own private “lab” using old spare computers. All these computers ran Linux, so I started to learn about network services including Apache, DHCP and Samba.

Below is the second in a series of posts by actual Red Hat Certified Professionals offering their preparation tips for taking Red Hat exams. The thoughts and opinions expressed here are the author’s and not necessarily those of Red Hat Training.
When I began with Red Hat Enterprise Linux (RHEL), I started with zero knowledge. As a system administrator, I had been working mostly on other operating systems, but not on RHEL. I had been asked to set up a server for a client that wanted a Linux environment because of its stability and performance with clustered environments, so I quickly browsed for Red Hat courses for and enrolled in class. After completing the course, next came the heart-stopping RHCSA exam, but I wasn’t that worried since I felt prepared for that day.

One of the new features introduced in version 3.1 of Red Hat Enterprise Virtualization is a command line interface (CLI) to connect to the manager. The CLI also contains a scripting system, which helps system administrators perform periodic maintenance or repetitive tasks on their virtualization environment.
Communication with the RHEV Manager is secured through the use of a certificate that needs to be downloaded from the manager:
$ wget http://rhevm.pod0.example.com/ca.crt
Connect to the RHEV Manager using the rhevm-shell command (referring to the downloaded certificate):

Below is the first in a series of posts by actual Red Hat Certified Professionals offering their preparation tips for taking Red Hat exams. The thoughts and opinions expressed here are the author’s and not necessarily those of Red Hat Training.
I have been working for Red Hat for over 5 years, and throughout these years I have had the opportunity to take several Red Hat Training courses and earn a few certifications. These certifications include: Red Hat Certified Engineer (RHEL5, 2007), Red Hat Certified Architect (2010) and Red Hat Certified Engineer (RHEL6, 2012).
So, when I read that the good people at Red Hat Training were looking for some ‘How do you prepare’ for Red Hat training courses and exams, I thought I had something to offer.
Red Hat Training courses are usually set up in a small classroom environment with 4 days of lectures, Monday through Thursday, and the exam on Friday. Throughout the years, the amount of time the exam takes has changed a bit, but one can be sure to take up at least your entire morning on Friday.
