Open source continues to be a tremendous source of innovation and nowhere is that more evident than at the biannual OpenStack Summit. Over the past couple of years, as OpenStack interest and adoption has grown, we’ve seen another important innovation emerge from the open source community in the form of Linux containers, driven by Docker and associated open source projects. As the world gathers in Tokyo for another OpenStack Summit, we wanted to talk about how Red Hat is bringing these two innovations together, to make OpenStack a great platform for running containerized applications.
Red Hat is not only contributing to innovation in OpenStack, but also in multiple Linux container communities including Docker, Kubernetes and Project Atomic. Red Hat was a driving force behind the creation of the Open Containers Initiative launched in June of this year with broad industry support, to create open industry standards around container formats and runtime. We also joined with Google and others to launch the Cloud Native Computing Foundation to drive innovations in container-packaged, dynamically scheduled and microservices-based application development and operations. We were excited to see Google join the OpenStack community, bringing with them their deep expertise in containers and web scale orchestration.

I’ve always enjoyed traveling to Tokyo, Japan, as the people are always so friendly and willing to help. Whether it’s finding my way through the Narita airport or just trying to find a place to eat, they’re always willing to help – even with the language barrier. And each time I visit, I see something new, learn another word (or two) in Japanese, and it all just seems new and exciting all over again. Add in the excitement and buzz of an OpenStack Summit and you’ve got a great week in Tokyo!
Since the official start of the OpenStack Summit is Tuesday, we’re mostly spending the day on Monday setting up and getting ready. The Red Hat team is working diligently to setup the booth, preparing our product demonstrations, and our session speakers are putting the final touches on their presentations.

In IT today, we love to note that the infrastructure layer has become commoditized. This started with virtualization, as we could create many virtual machines within a single physical machine. Cloud has taken us further with a key value proposition of delivering cloud services on any standard server or virtualized environment, enabling easier scalability and faster service delivery, among other benefits.
This commoditization argument has moved to the infrastructure software layer, with some conjecturing that the operating system running on top of hardware, hypervisor or container is also easily exchangeable. This is especially true with open source OSes. Ubuntu, Debian, CentOS and the many other flavors of community Linux are sometimes seen as interchangeable. This particularly has been an argument in the OpenStack community.

In this series we have seen the complexity of bridging the gap between existing infrastructure and processes (Mode 1) and new, agile processes and architectures (Mode 2). Each brings its own set of challenges and demands on the organization. In Mode-1 organizations are looking to increase relevance and reduce complexity, and in Mode-2 they are looking to improve agility and increase scalability. In this post we will discuss how Red Hat addresses and solves each of these challenges.
Introducing Red Hat Cloud Suite
Red Hat Cloud Suite is a family of suites from Red Hat that brings together all the award winning products from Red Hat in a consistent way to solve specific problems. It allows IT to accelerate service delivery and optimize their existing assets while allowing them to build their next generation infrastructure and application platforms to support massive scalability and more agile development and operations processes. In other words, it meets them where they are and lays the foundation for where they want to go.

In Part 2 of this series, we discussed what IT needs to do in a Mode 1 world to make itself more relevant to the business and reduce complexity. In this part, we will turn our attention to Mode 2 and discuss how the organization can solve its challenges by improving agility and increasing scalability.
Mode 2: Improving Agility by Modernizing Development and Operations
With resources now free from handling each and every inbound request for an environment and being confident that those environments are running efficiently and securely on the right providers, operations teams can begin to work with development teams to design new processes for their cloud native applications.

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.

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).

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:
- 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.

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.

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.
