Red Hat is best known for Red Hat Enterprise Linux (RHEL) and for being a leader in driving open source development projects. In many cases, the upstream projects then become Red Hat products that provide enterprise functionality elsewhere in the stack.
In a previous blog post, I detailed how we use Red Hat Single Sign On (SSO) to provide a robust and scalable authentication system for public web properties. Applications, such a Red Hat SSO, can obviously be deployed in a variety of platforms. Red Hat IT selected to adopt a hybrid-cloud deployment model for Red Hat SSO, as the majority of normal traffic for https://sso.redhat.com is serviced out of one of our corporate data centers. SSO and virtually every other application runs on top of Red Hat Virtualization.

Red Hat IT makes extensive use of our own product offerings to effectively manage and to scale our large IT infrastructure. Red Hat Virtualization plays a key role in Red Hat’s overall IT infrastructure, as mentioned in a recent blog by the head of our IT Platform Operations team, Anderson Silva: Red Hat Keeps the Lights on with Red Hat Virtualization

Red Hat Virtualization offers a flexible technology for high-intensive performance and secure workloads. Red Hat Virtualization 4.0 introduced new features that enable customers to further extend the use case of traditional virtualization in hybrid cloud environments. The platform now easily incorporates third party network providers into the existing environment along with other technologies found in next generation cloud platforms such as Red Hat OpenStack Platform and Red Hat Enterprise Linux Atomic Host. Additionally, new infrastructure models are now supported including selected support for hyperconverged infrastructure; the native integration of compute and storage across a cluster of hosts in a Red Hat Virtualization environment.

The usage of open source technologies has grown significantly in the public sector. In fact, according to a published memo, open source technologies allow the Department of Defense to “develop and update its software-based capabilities faster than ever, to anticipate new threats and respond to continuously changing requirements”. Cybersecurity threats are on the rise and organizations need to ensure that the software they use in their environments is safe. IT teams need the ability to quickly identify and mitigate breaches. They also need to deploy preventative measures and ensure that all stakeholders are protected.

I attended the KVM Forum in August of this year, and as a new Red Hatter with a lot of VMware experience, it was eye opening. I am seeing a lot of interest in Red Hat Virtualization from my customers, and so I wanted to understand the platform at a much deeper level. KVM is the technology that underpins the Red Hat Virtualization platform. A number of themes emerged for me as I attended sessions and enjoyed the hallway track. This was a forum for developers by developers, so infrastructure types like myself were far and few between but that did not impact my enjoyment of the conference. In fact, as a technical guy coming from a server background, I learned a lot more than I would have learned from a typical infrastructure focused conference. Below, I will highlight some topics that stood out to me.

Red Hat has been a technology industry leader for many years. We are not just creators of innovative open source technologies, but we are also consumers of our own technologies. At Red Hat, nearly all of our core IT infrastructure runs on Red Hat Virtualization. From our development environment all the way to production. Several of our mission critical applications are powered by Red Hat Virtualization including our email systems, identity management, subscription manager, customer service portal, and many more applications. Since we are a global company, we have deployed thousands of VMs that need to be up and running 24/7, and we chose Red Hat Virtualization to get the job done.

This past August, Red Hat announced the availability of Red Hat Virtualization 4.0, the latest virtualization release that aims to help IT organizations modernize their infrastructure, enhance their virtualization management and automation, and deploy advanced networking functionality. As a Software Engineer, I know that releases are exciting and early adopter customers eagerly await for the opportunity to deploy the latest features. However, the the upgrade process has not always been seamless. Through my work with the Customer Support Team, we have been exploring tools to streamline and simplify the upgrade process.

Six months ago we announced the beta availability of Red Hat Enterprise Linux 7. Two months ago, at Red Hat Summit 2014, we announced the availability of a release candidate for Red Hat Enterprise Linux 7. All the while we have been validating what’s new, different, and exciting about what Red Hat Enterprise Linux 7 has to offer – including:
Today we are pleased to announce the general availability of Red Hat Enterprise Linux 7, the latest major release of our flagship platform. As stated in this morning’s press release:

Ever since Red Hat Enterprise Linux added KVM Virtualization as a kernel-based hypervisor to run virtual machines (way back in Red Hat Enterprise Linux 5.4), the operating system took on a dual personality.
Red Hat Enterprise Linux became both a Virtualization host for high density virtual data centers / cloud service platforms, and a guest operating system running on third party hypervisors such as VMware vSphere and Microsoft Hyper-V. As the topic is sufficiently broad, I plan to split my discussion of virtualization into two posts.
Today’s post will discuss Red Hat Enterprise Linux 7 beta as a hypervisor using KVM Virtualization technology and it will highlight a few key enhancements that make Red Hat Enterprise Linux the operating system of choice for modern hybrid data centers. While the features that I will review are inherently those that I find to be the most exciting (note: I’m hoping you will find them to be exciting and useful as well), a complete list is available in the Red Hat Enterprise Linux 7 beta release notes.
