By default, the packstack installer uses either a volume group named cinder-volumes or a loopback device as back end for the Cinder block storage service. For professional purposes, this is not enough; the usual requirement is to have a redundant storage back end. If you have an existing Red Hat Storage service, you might want to use one of the GlusterFS volumes as back end for the block devices your virtual machines use in the Red Hat Enterprise Linux OpenStack Platform cloud.
Before starting the configuration, you must remove all existing Cinder volumes, or you will run into problems. To figure out if there are any existing volumes with your current Cinder setup issue:
If there are any volumes listed, delete them with:
cinder delete volumename
Now that you have a cleaned-up Cinder setup, you can configure the back end to exclusively use the Red Hat Storage GlusterFS volume(s).
Start off by installing the GlusterFS-fuse package on the Cinder host, available in the Red Hat Storage Native Client repository from Red Hat Network.
yum -y install GlusterFS-fuse

When Cigna developers needed to improve their application testing processes, they teamed up with Red Hat Consulting to implement agile methodologies. Iterative development has helped Cigna prioritize features based on customers’ needs, and as a result, the quality of Cigna’s software has improved.
In the video below, representatives from Cigna and Red Hat Consulting discuss how working together to instill behavior-driven development principles helped Cigna:
• Increase speed to market by aligning application delivery with customer expectations.
• Reduce risk by engaging subject matter experts and stakeholders in regular reviews.
• Sustain application quality by identifying and fixing defects early in project life cycle.
• Ensure on-time delivery and predictable performance.

To install Red Hat Enterprise Linux OpenStack Platform manually can be an odious task, but packstack can assist in making the installation much easier and consistent. Normally, packstack is run from the controller node, which can either be a physical machine or a virtual machine.
Start by installing the machine with the latest Red Hat Enterprise Linux. Subscribe to the Red Hat OpenStack channel, as well as any other channels desired.
Next, install the openstack-packstack package using yum:
~]$ sudo yum install openstack-packstack
As root, use packstack to generate an answer file:
~]# packstack –gen-answer-file ~/answers.txt

Today’s business leaders want more innovation, faster. They know that, in order to beat competitors and continue to thrive, their organisation must excel in bringing new products and services to market at speed and on consistently exceeding customer expectations.
That puts major pressure on those responsible for developing and delivering new and enhanced software functionality for the business to use. More frequent releases and shorter deadlines are increasingly becoming facts of life, but in the race to fast-track new pieces of code, IT teams often hit a roadblock.
That roadblock occurs at the boundary of application development and IT operations, an intersection where two very different cultures meet.
On one side of the boundary is the culture of the developer, where creativity, freedom to experiment and choice of tools are paramount. The developer is happiest using Agile techniques to produce a constant stream of software releases and upgrades that will get the business where it needs to be, in terms of innovation.
On the other side of the boundary is IT operations, where stability and control are what matters. Disruption is the enemy and frequent software releases can be complex to manage. IT operations agree that they want the business to move forwards – but not at the risk of critical systems falling over.

During this year’s Red Hat Partner Conference EMEA in Madrid, Spain, Red Hat Training gave an update on its new training and certification roadmap. The event covered new delivery methods and courses, including a three day exam marathon during which a total of 70 partner employees had a chance to take a free-of-charge certification exam. In addition, a training partner round table was held to discuss new opportunities for Red Hat Training and our partners. As is tradition, we also held an awards ceremony, recognizing those that have made the biggest impact over the course of the last year in training and certifications.
It is with great pleasure that I reveal the awards given that night:

Based in Southern California, with five offices in Los Angeles, Orange, San Diego and San Bernardino counties, New Horizons Computer Learning Centers of Southern California was recently named Red Hat Training’s Ready Partner of the Year at the annual Red Hat Training Partner Conference in Las Vegas, NV. As part of the world’s largest independent IT training company, New Horizons Computer Learning Centers of Southern California is a learning solutions provider for the industry’s top vendors, and has been a Red Hat Training Partner since 2010. We recently caught up with New Horizons Computer learning Centers of Southern California’s CEO, Kevin Landry, for his thoughts regarding the state of the training industry today and how it will change tomorrow.
Who are you training these days?
The market we’re in is a little bit unique. 70% of our business is considered B2B or enterprise business, companies like Disney, Southern California Edison, and Ingram Micro. Working with Red Hat over the past several years, we’ve continually seen this business double year after year. Developers in training is the largest growth area, but the greatest area of interest we’ve seen increase has been in the consumer market, where individuals fund their own training. I’d say 30% of the individuals that we train fall into this latter group, and are funding training on their own or have alternative government funding, such as VA benefits or unemployment benefits.
What are the most common reasons people are getting trained right now?
Skill shortage is the main reason that individuals are seeking training, and being that it’s more likely these days to see Linux or Red Hat in a job description, we’ve seen a lot of growth in consumers seeking Red Hat Certifications.
