Today we released the seventh update to Red Hat Enterprise Linux 4, marking the point where Red Hat Enterprise Linux 4 enters the autumn of its life cycle. Red Hat Enterprise Linux 4 is now marching toward the Production 2 life cycle phase — formerly known as the “Transition” or “Deployment” phase. From this point forward, the amount of change introduced for Red Hat Enterprise Linux 4 minor releases is decreasing constantly as Red Hat focuses its efforts on addressing continued stabilization of the release.

A recent blog accompanying the release of the Red Hat Enterprise Linux 5.2 update discussed the value of the life cycle of Enterprise Linux. And in June, during a presentation at the Red Hat Summit in Boston, we mentioned our plans to improve the current life cycle in an effort to provide the coverage that our customers and partners have been requesting.
So, as of today, the first phase of the life-cycle for every Red Hat Enterprise Linux major release is being extended from three years to four. During the first phase of the life cycle we provide support for new hardware that is released by our partners, important new software functionality, bug fixes and security patches.
This extension of the first life cycle phase provides a simple but important benefit for customers: it will be possible to purchase new hardware and find that it is supported on your deployed version of Red Hat Enterprise Linux for an additional year. Similarly, it will often be possible to take advantage of new software features that would previously have required an upgrade to access.

The environment and green issues have become pervasive across all facets of life. Everyone is keen to ‘go green’ whether it’s cutting down on water usage, recycling, driving a hybrid car or any number of other initiatives. It’s no different at Red Hat, where we are working hard to deliver greener products and solutions. A recent Network World test examining power consumption to determine the ‘greener’ operating system validates Red Hat’s efforts to move toward green computing.
Network World ran multiple power consumption tests using Red Hat Enterprise Linux 5.1, SUSE Enterprise Linux 10 SP1 and Windows Server 2008 Enterprise Edition on servers from Dell, IBM and HP. Red Hat Enterprise Linux ranked at the top in keeping the power draw in check, pulling as much as 12 percent less power than Windows 2008 on identical hardware. This reduced power draw was evident across testing in both performance and power saving modes and transcended all server models used in the test bed.

With the recent release of Red Hat Enterprise Linux 5.2, the kickoff of the HP Technology Forum on Monday and the upcoming Red Hat Summit taking place later this week in Boston, Mass. — we wanted to share details about joint activity between Red Hat and HP.
Red Hat and HP together provide powerful integrated solutions for customers who want the confidence of deploying Red Hat Enterprise Linux on robust certified systems with comprehensive services and seamless support.

Today we released the second update to Red Hat Enterprise Linux 5. As with earlier minor releases, Red Hat Enterprise Linux 5.2 comes with a broad set of bug fixes, updated hardware support capabilities, quality improvements, and a set of new software features that have been backported from upstream open source projects to the Enterprise Linux 5 code base.
Of course, we don’t normally make a big deal about the release of a minor version, but for this update we’ve decided to go wild and issue a pair of blogs. In this one we will talk about the new features and capabilities on Red Hat Enterprise Linux 5.2. In the other we will highlight something that we are proud of and applies to all Red Hat Enterprise Linux releases, our software maintenance and lifecycle policies.
Red Hat Enterprise Linux 5.2 enhancements we are releasing are primarily focused in six areas:
This is one of two Red Hat Enterprise Linux-related blogs released today. It highlights something that we are proud of and applies to all Red Hat Enterprise Linux releases, our software maintenance and lifecycle policies. The other blog covers the new capabilities provided by Red Hat Enterprise Linux 5.2.
We have done a lot of work to make sure that minor releases, such as 5.2, deliver subscription value to customers. We try to strike a balance between adding improvements, which enhance customers’ ability to get more value from their IT assets, but not adding so much that it causes them to have to recertify their entire software stack. And we make it easy for customers to apply these updates by using Red Hat Network.

Today we released a set of para-virtualized (PV) drivers for use with fully-virtualized (FV) Red Hat Enterprise Linux guests running on a Red Hat Enterprise Linux 5.1 (or later) host.
Red Hat Enterprise Linux 5 introduced native virtualization support when it was released in March 2007. This provided PV guest support for Enterprise Linux 5 guests, offering one of the lowest possible virtualization overheads for applications. PV guest support was subsequently extended to Red Hat Enterprise Linux 4 guests with the 4.5 minor release. Additionally, support for FV guests, which offers the ability to run the same kernel as a non-virtualized system, albeit at lower performance, was also provided.
In performance tests it was clear that PV guests running CPU-centric workloads have less than 5 percent virtualization overhead, while even the most demanding I/O intensive tasks, such as webserving and high performance database I/O loads, perform within 85 percent of bare-metal performance.

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.

An interesting new report — “The Role of Linux Servers and Commercial Workloads” — sponsored by The Linux Foundation and published by IDC, provides some impressive facts and opinions about the health of the Linux server market.
Quoting from the Summary: “Spending on software related to Linux SOE [Server Operating Environment] platforms is growing quickly - with a 2006-2011 CAGR of 35.7%. Overall spending on Linux SOEs, including software, hardware, and services, is increasing at a 2006-2011 CAGR of 24.1%.”
The report goes beyond the standard operating system view by including data on application deployments and breakdowns of Linux usage by vertical market. It also offers IDC’s views of Challenges and Opportunities facing the Linux SOE market today.

For the last few years, Red Hat has been a regular fixture at the RSA Conference, and this year will be no different. We will be showing the recently open sourced Certificate System Dogtag project and we’ll be launching the beta program for Red Hat Enterprise IPA. Red Hat Enterprise IPA is a new product, scheduled for release mid-year, that is based on the open source freeIPA, centralized Identity, Policy and Audit project. At the Red Hat booth at RSA, we will have a demo showing the high-level features of Red Hat Enterprise IPA, so if you are interested in participating in the beta program please visit us at the show, or sign up for more information about the beta.
Identity and access management is important for reasons of efficiency, risk reduction and compliance. Existing solutions are either no longer compliant (NIS), expensive or not that easy to use (do-it-yourself LDAP and perhaps Kerberos). Red Hat’s acquisition of Netscape’s Directory Server and Certificate System was just the start of our identity and access management strategy.
