Since the announcement of RDO and Red Hat OpenStack at the Spring 2013 OpenStack Summit, these have arguably become two of the most popular ways to install OpenStack. Both use the puppet-openstack modules to install OpenStack, and are just a sampling of the OpenStack installers that are based on Puppet.

Tim’s earlier posts include:
As described in my earlier posts, it is plain to see that Red Hat is not treating OpenStack as “just” a layered product.
Rather, Red Hat Enterprise Linux OpenStack Platform is the next major evolution in the Red Hat Enterprise Linux family. The tight levels of integration and responsible enterprise grade feature enhancement necessitate this combination. We believe that doing OpenStack right – to make it secure, performant, easy to use, and evolve over time – is only possible by taking a holistic approach.

In my last post, I discussed a small subset of the security, storage, networking, virtualization, and performance optimizations that make the Red Hat Enterprise Linux OpenStack Platform offering technically superior. Yet, as innovation continues in the vibrant upstream OpenStack and Linux communities, Red Hat’s integration work is ongoing. Our subscription model assures that customers will continue to have access to this ongoing stream of innovation – innovation that is made possible through the tight coordination of the Red Hat Enterprise Linux development team, which now includes OpenStack components. The goals of that coordination include:
- Component Integration – There are several parts of OpenStack that have dependencies on specific versions of run-times or system utilities. For example, there are specific networking modules required for software-defined networks (SDNs), specific versions of python run-times, custom Security-Enhanced Linux (SELinux) security policies, and even system tunings for virtualized guest environments. Piecing together the specific versions and making the completed whole function optimally can be a daunting challenge.

OpenStack delivers a highly scalable cloud environment for a variety of applications. But, cloud workloads present new challenges for underlying operating system platforms. The nature of the cloud is to be agile, not static. Virtual machines are quickly created and destroyed in large numbers. Storage and networking need to be flexible and highly performant. Red Hat Enterprise Linux has evolved to match the pace and unique characteristics of cloud deployments and is optimized for OpenStack in several ways, including:
- Security – Cloud environments don’t deploy applications on dedicated hardware. Rather, they deploy multiple virtual machines on top of a pool of generic hardware resources, with virtual machines often sharing the same hardware. In this deployment model, virtual machine isolation is a key security concern. Enter Red Hat Enterprise Linux and the fine-grained permission enforcement afforded by Security-Enhanced Linux (SELinux) at the file, network and user levels. In Red Hat Enterprise Linux OpenStack Platform, SELinux enforces specific policies that are unique to the needs of OpenStack, such as enabling OpenStack to configure network namespaces which utilize Openstack’s network services. The benefit of SELinux is to prevent different virtual guests from accessing network ports and connections maliciously. In this way, the security inherent in Red Hat Enterprise Linux enhances the security of OpenStack cloud environment.

Throughout its history, Red Hat Enterprise Linux has been been transformative in the information technology infrastructure platform arena. It was founded on the principles of bringing stability and a longer lifecycle required by commercial IT organizations to the rapidly changing, community-developed Linux operating system. This unleashed a wave of commoditized computing as Red Hat Enterprise Linux displaced expensive proprietary UNIX offerings, delivering customers lower costs and freedom from vendor lock-in.
The next wave of Red Hat Enterprise Linux focused on being first in the industry to offer the highest levels of security built into the mainstream product rather than being an obscure offshoot. This focus on security – including collaboration with the U.S. government’s National Security Agency (NSA) on Security-Enhanced Linux (SELinux) – paved the way for security-conscious governments and businesses around the globe to adopt Red Hat Enterprise Linux.

We are pleased to announce the continued evolution of Red Hat’s training and certification programs in support of Red Hat Enterprise Linux OpenStack Platform, which delivers Red Hat OpenStack technology optimized for and integrated with Red Hat Enterprise Linux. This week we are announcing the expansion of our core system administration course on, Red Hat OpenStack Administration, from three days to four so we can drill deeper into this emerging technology. We have re-titled the Red Hat Certificate of Expertise in Infrastructure-as-a-Service to Red Hat Certified System Administrator in Red Hat OpenStack. We want to make sure IT professionals worldwide understand what we are certifying with this important new credential. In coming months we plan to add to our OpenStack course and exam offerings. If you are attending Red Hat Summit, please consider one of the training events we will be offering there.

As many of you know, OpenStack is a fully distributed system. As such, it keeps its services (nova, glance, cinder, keystone, etc ) as decoupled as possible and tries to stick to most of the distribution paradigms, deployments strategies and architectures. For example, one of the main tenets throughout OpenStack is that every module should be using Shared Nothing Architecture (SNA) which states. that each node should be independent and self-sufficient. In other words, all nodes in a SNA are completely isolated from each other in terms of space and memory.
There are other distribution principles that are part of OpenStack’s tenets, however, this post is not about what principles OpenStack as a whole tries to follow, but rather on how OpenStack sticks together such a heavily distributed architecture and makes it work as one. The first thing we need to do is evaluate some of the integration methods that exist out there and how they’re being used within OpenStack. Before we get there, let me explain what an integration method is.

In spite of its considerable momentum, there are still skeptics about whether OpenStack will ultimately succeed. My colleague Bryan Che tackled some of that skepticism in a blog post late last year and I’m not going to rehash his arguments here. Rather, I’m going to make some observations about how OpenStack is paralleling and will likely continue to parallel the adoption of another open source project that I think we can all agree has become popular and successful—namely Linux.
1. Part and parcel of a new approach to computing
Linux came about at a time when computing was changing. It had become distributed and the rise of the Web was leading to new functions and new requirements. Much of Linux’ early-on growth came from powering new Internet infrastructure. It was from that beachhead that Linux branched out into more traditional enterprise operating system roles. Similarly, OpenStack is part of the cloud computing wave which is characterized by new levels of standardization and automation combined with an on-demand and self-service approach to delivering computing resources to users.

This week heralds a refresh of Red Hat’s cloud portfolio offerings, including Red Hat Cloud Infrastructure 4.0, Red Hat Enterprise Linux OpenStack Platform 4.0, and the latest release of Red Hat’s traditional data center virtualization management platform, Red Hat Enterprise Virtualization 3.3.
We’ve put a lot of effort into our long-term cloud product strategy and the updates this week show the beginning of those efforts coming together. With this refresh, it’s clear that integration and management is the key theme behind the marketing launch activities. However, delivering real, tangible, and deployable value to our customers through Red Hat infrastructure software, is the key to success for us and this update provides you (us) the first step.
So why is integration so important in your data center? And why integrate with OpenStack? The answer lies within your own existing infrastructure, as well as your long-term plans. No, I don’t have magical powers to see your datacenter or your plans, but statistically-speaking, I can see just fine.
