DevOps in a Bi-Modal World (Part 2 of 4)

In Part 1 of this series we explored how IT is now faced with the challenges of what Gartner calls a Bi-Modal world where the business must continue working with their existing infrastructure and processes (Mode 1), while at the same time developing new processes and building new infrastructure to become more agile (Mode 2). The challenges are complex and we concluded that most organizations are trying to address four key problems across their emerging bi-modal world.

In mode-1 they are looking to increase relevance and reduce complexity.

In mode-2 they are looking to improve agility and increase scalability.

Here, we will discuss in more detail how organizations can address the challenges of Mode 1.

Red Hat and Lenovo: More Choice, More Clouds

In August 2015, we released Red Hat Enterprise Linux OpenStack Platform 7, bringing some of the latest innovations of OpenStack to the enterprise in a hardened, production-ready, and simple-to-deploy solution. The latest version of Red Hat’s Infrastructure-as-a-Service (IaaS) offering, based on the security and reliability of the world’s leading enterprise Linux platform, Red Hat Enterprise Linux OpenStack Platform 7 delivers a host of enhancements, including:

  • A new orchestration and management tool, Red Hat Enterprise Linux OpenStack Platform director;
  • Improved network flexibility with Neutron;
  • Enhanced object and block storage functionality with integrated Red Hat Ceph Storage Server; and
  • A fully supported bare-metal deployment service (Ironic).

DevOps in a Bi-Modal World (Part 1 of 4)

Driven by technology, the business world is rapidly changing and disruption is everywhere. The new reality for businesses is that in order to compete they must rapidly develop and deliver services to their customers, as well as to their own organization. There is much riding on IT to develop the infrastructure and processes needed to deliver services while at the same time working with existing assets and processes. In in this four part series we will explore how the business environment is changing, the challenges to IT, what needs to be done and solutions.

New realities for businesses

The business environment has never been more competitive and disruptive than it is today. Businesses need to come to terms with three realities:

  1. They need a continuous competitive advantage

Just ask Kodak who has seen the camera business transform from a standalone device to a feature on every mobile phone with new players like Snapfish, Shutterfly, and Chatbooks creating new ways of engaging with markets. If you don’t have a way of continually developing new competitive advantages you will not be relevant for long.

Troubleshooting Networking with RHEL OpenStack Platform: meet ‘plotnetcfg’

Network troubleshooting can be hard. Network troubleshooting in a complex distributed system like OpenStack can be even harder. With a typical Neutron deployment using the Open vSwitch (OVS) plug-in, one can expect rich networking configurations on the Red Hat Enterprise Linux OpenStack Platform nodes, the Compute and Controller nodes in particular.

While the network implementation details are well hidden from the end customer (who interfaces with the Neutron API or the Horizon Dashboard), the actual backend implementation involves the creation of various Linux devices, bridges, tunnel interfaces, and network namespaces. This is where the “magic” happens, and how OpenStack tenants can create and consume network resources such as networks, IP subnets and virtual routers, and get proper communication for their applications.

What’s new in OpenStack Liberty: webinar recap

OpenStack “Liberty,” due for imminent release, represents the 12th release of the open source computing platform for public and private clouds. Recent OpenStack releases have focused on improving stability and enhancing the operator experience. This is still the case with Liberty, but there are still new features to consider.

On October 1st we provided a sneak peek into the highlights of OpenStack Liberty, if you missed out you can now view the recording of the event on demand. As well as providing an overview the highlights of the Liberty release we also discussed the recent restructure of the way governance of OpenStack projects works, colloquially referred to as the “big tent”, and what it means for you as a consumer of OpenStack.
