Red Hat Information Technology has created a new middleware architecture for our internally-developed applications. Although many of our internal applications take advantage of open source solutions, we have historically used tools such as Tomcat and Perl on a standalone basis and not taken full advantage of our JBoss application stack.
We’ve defined our new middleware architecture based on JBoss technology. This includes an Enterprise Service Bus implementing a Services Oriented Architecture (SOA); Seam, the JBoss integration framework; the JBoss Business Process Modeling suite (JBPM); and Drools, the JBoss rules processing environment.
The entire stack runs on Red Hat Enterprise Linux, taking advantage of the operating system tools for virtualization, provisioning, configuration, and other functionality. The full technical architecture incorporates Cobbler/Koan, JBoss SOA, Xen, LVM, Git, and more.

It’s no secret that Red Hat is a leading contributor to the development of open source software. In fact, as noted by a couple of recent surveys, Red Hat is the leading corporate contributor to the most important open source project of all, the Linux Kernel.
Last week, the Linux Foundation published a report about Linux kernel development and we were recognized as the leading corporate contributor with over 9,000 changes contributed, or 11.2 percent of the total. And we were also recognized a few months ago by Linux Weekly News as the most active company contributor both by changesets (12 percent) and by lines changed (12.7 percent) in the development of the 2.6.23 kernel. The results for these two reports are summarized in the following table:
| Top 6 Corporate Contributors | |||||
| Linux Foundation | Linux Weekly News | ||||
| Company Name | Changes | % of total | Company Name | Changes | % of total |
| None | 11,594 | 13.0% | Unknown | 1,180 | 19.0% |
| Unknown | 10,803 | 12.9% | Red Hat | 744 | 12.0% |
| Red Hat | 9,351 | 11.2% | None | 559 | 9.0% |
| Novell | 7,385 | 8.9% | IBM | 507 | 8.2% |
| IBM | 6,952 | 8.3% | Novell | 421 | 6.8% |
| Intel | 3,388 | 4.1% | Intel | 184 | 3.0% |
In the middle of the great discussions and conferences taking place at JBoss World, Orlando, Red Hat quietly leaked out the first cut of what is likely to influence the future of virtualization. Project oVirt. oVirt’s aim is to transform the host virtualization layer into a small stateless image which can be embedded on FLASH, or booted off a CD or PXE. No local disks needed. No installs. A physical server can become a virtual server just by booting oVirt.
oVirt also includes a new web management console which can manage any libvirt-based virtualization system. Whether that be one personal system, or the enterprise. It is no accident that oVirt is tightly integrating with the freeIPA project, so that administrators will be able to authenticate, authorize, and audit their virtual resources across the enterprise.
Not a bad week.
A new breed of appliance is emerging. Not unlike their kitchen counterparts, the goal in using these appliances is to plug them in and use them, not to spend hours installing them, configuring them, tuning them and maintaining them.
These appliances are built using software.

Today, the Red Hat crew announced a new offering called “Red Hat Enterprise MRG.” What is MRG? It is an interesting set of technologies (Messaging, Realtime and Grid) which, when combined, we believe will provide unprecedented value, power and flexibility to our customers. We have received feedback from our customers stating that in the same way they where able to get better performance using less hardware and at less cost when moving to Red Hat Enterprise Linux from other operating systems, they expect the same will happen when using MRG. This provides the next big building block in Red Hat’s Linux Automation story. More on this later. First, lets look at some of the pieces.

Red Hat has shown that open source is one of the best ways to bring customer-driven innovation and leadership to the market. Today’s announcement of Red Hat Enterprise MRG provides a perfect example of this in many respects.
Red Hat Enterprise MRG includes Red Hat’s implementation of AMQP-based ( Advanced Message Queuing Protocol) enterprise messaging. Both the MRG Messaging implementation and AMQP itself highlight Red Hat’s leadership and customer-driven innovation.

Today Red Hat made some announcements, under an umbrella theme of Linux Automation. At first glance, this would seem surprising. But when you tear it apart, a focus on automation makes extreme sense.
Go back 10 years and look what was happening in the processor space. Price/performance of Intel CPUs was challenging the legacy RISC systems. Microsoft was the largest benefactor of this, while the OEMs clung to their high margin UNIX/RISC systems. Who could blame them.
In 2001 Red Hat squarely focused on the commercial enterprise systems business. The enabler for this was no longer solely price/performance of x86 systems. But the recognition that technically, Linux had matured to the point to not just be an alternative to UNIX/RISC, but actually a market leader. Enterprise Linux was born, along with pioneering a subscription model that would keep us focusing on customer satisfaction and service rather than just the initial sale.
Today, millions of servers around the world are powered by Enterprise Linux. The heroes being the IT departments which made this choice, challenging the legacy before it was mainstream. What now is the obvious choice due to performance and cost.
The last 6 years have been focused on UNIX migration, allowing x86 performance to be realized, and building software subscription capabilities. In the next chapter we believe that Enterprise Linux will continue to take share against Windows solely based on performance, stability, and cost. However, basically due to impatience we wish to accelerate what has already become a behavioral norm for IT.
Linux Automation. The ability to run any application, on any system, at any time. Allowing IT to simplify their IT infrastructure in the process. With the belief that undue complexity and over-architecture will have both short and long term costs.
Any Application.
The RHEL application world, at 3000+ certification strong, is growing at the rate of approximately a new application every day. Application choice is critical for IT. The stability of the RHEL platform, and its release-to-release continuity allows application growth to continue without disruption.
Anywhere.
The move to x86 marked an inflection point for IT from the traditional use of large RISC servers. Today, the footprint which makes up the IT arsenal looks increasingly differentiated, allowing the right server to be matched with the right task. Rack-mount. Blades. 128-way SMP. Mainframes. PowerPC and Itanium. Virtualized servers based on VMWARE and RHEL 5. We want to enable IT choice, not dictate it. And deliver a consistent RHEL platform across each which drives IT simplicity, while allowing ISVs to reach all markets at low cost. Today we announce that the platform choice for RHEL has extended one further. Dedicated and virtual servers are now joined by a 3rd twin, with RHEL being available as an on-demand choice as part of Amazon EC2. With a supported ISV catalog 3000+ strong.
Anytime.
When the first version of Enterprise Linux was released in May of 2002, a physical system and its applications typically had a one to one affinity. The models of moving applications from one system to another was usually only realized at failover time, requiring costly hardware and hard labor to realize. Today the technology is in place to flip this. RHEL5 with integrated virtualization has built application mobility into the OS. Transparent to all applications on the platform. The resources apportioned to an application can be changed on demand. Applications can be live migrated to another system, ending the scheduling of planned outages. High availability delivered to all applications on the platform, at low cost.
To the 1000s of customers to whom Linux, OSS, and Red Hat has earned their trust, we thank you. The journey of the impact of open source software on your businesses has just begun.
Linux Automation. Any application. Anywhere. Anytime.
I was invited to do a presentation at the High Performance on Wall Street conference in New York City on September 17 to discuss Red Hat’s realtime development project. For the benefit of those not in attendence, I’ll briefly recap the main points of my talk here.
My main intention was to help the audience become more informed. I consider this important because realtime offerings have been getting a lot of buzz lately, but the term itself and true benefits of realtime are often not well understood. Realtime is a great fit for many deployments, but it is not a silver bullet for all performance woes. The more informed the customer is, the better prepared they are to follow the right path to their performance objectives.

The decision by AMD to provide Open Source 2D and 3D drivers for R5xx/R6xx and future GPUs graphics hardware is a great development for the open source community, for AMD and for customers. Here are some of the details of this exciting news.
Highlights:
Over the past few years, a lot of IT hype has been expended on virtualization technology. It was ready for prime time, or it wasn’t; everybody was using it already, or they weren’t; it was expensive, or it wasn’t; and so on. Now that Red Hat Enterprise Linux 5 has been available for a few months, we are starting to see how customers are actually going to use virtualization. This allows us to get to the truth behind the hype.
