How to use a Red Hat Storage volume as Red Hat Enterprise Linux OpenStack Platform Cinder block storage back end

by Rudi Kastl, curriculum manager, Red Hat

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:

source /root/keystonerc_admin
cinder list

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

Cigna becomes more agile with behavior-driven development

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.

Getting developers and IT operations working together

by Alan Hale (Red Hat)

This post originally appeared in DeveloperTech.

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.

Conflict resolution

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.

Red Hat announces new OpenStack certification

by Iain Gray, vice president, global services, Red Hat

Today is an exciting day for Red Hat as we announce our new Red Hat Certificate of Expertise in Infrastructure-as-a-Service and expanded training in support of Red Hat’s OpenStack technology.

We launched Red Hat Enterprise Linux OpenStack Platform at the Red Hat Summit in June as a core part of our open hybrid cloud strategy. There is a huge amount of excitement about OpenStack both at Red Hat and from our customers. In terms of company focus, it truly is “the next Linux.” Our goal is to bring our enterprise experience to the Infrastructure-as-a-Service (IaaS) market and provide an OpenStack platform that our customers can trust.

We are committed to providing services that help our customers use OpenStack to get their products to market faster. We recently launched a range of IaaS-focused offerings. From cloud migration strategy consulting, to Red Hat Enterprise Linux OpenStack Platform product-pilot implementation services, through complete IaaS-based solution development, we can support our customers through every stage in their cloud journey. Red Hat OpenStack Administration (CL210), a course we introduced earlier this year, helps customers build their teams’ readiness to adopt and use this new technology.

Today, we complement and expand these offerings by introducing the Red Hat Certificate of Expertise in Infrastructure-as-a-Service and expanding the Red Hat OpenStack Administration course to cover new capabilities in the latest release and to provide preparation for the Red Hat Certificate of Expertise in Infrastructure-as-a-Service Exam (EX210).
