Red Hat Enterprise Linux on Azure? .NET as an RPM and Container from Red Hat? Sweet!

Six years ago, we worked closely with Microsoft to deliver on a significant and widespread customer request: the ability for our respective operating systems to function as guests on each other’s hypervisor. This was then codified by the certification of Hyper-V as a supported hypervisor for use with Red Hat Enterprise Linux and the certification of Red Hat products as supported hypervisors for use with Windows which both companies have maintained for the past six years.

More than half a decade later, customers are now asking Red Hat and Microsoft to have Red Hat Enterprise Linux as a supported guest in the Azure Cloud. We both heard you! Thanks to a deep commitment by both companies, this day has arrived and, together, we are responding to another important customer ask with full support.

As the game show host says, “But wait! there’s more!” In March 2014, we announced that we were bringing Microsoft .NET capabilities to OpenShift Origin. We now expect that Microsoft .NET capabilities will grow past OpenShift Origin to include

Configuring and Applying SCAP Policies During Installation

Over the past few decades we have seen great advancements in the IT industry.  In fact, the industry itself seems to be growing at an increasingly faster pace.  However, as the industry grows so to does its evil twin – the figurative sum of all threats to IT security.

On the bright side, along with a steady stream of ever-evolving security issues and threats, there has also been a great effort to mitigate and, when possible, entirely eliminate such threats.  This is accomplished by either fixing the bugs that allowed these issues and threats to exist (in the first place) or by fixing the configurations and protectionary mechanisms of systems so as to prevent attackers from finding success.

As 2015 has been no stranger to news stories about data leakages, various security flaws, and new types of malware – one could easily conclude that “the dark side” is winning this seemingly eternal race.

However, taking the complexity of today’s IT solutions into account

Business Intelligence for the Real-Time Enterprise

The ocean of data coursing through your business can be a blessing or a curse.

If you can use your data to spot opportunities as they appear, it can mean the difference between success and failure. Unfortunately for many companies, key performance indicators and other metrics reporting can involve long waits due to complex legacy systems burdened by large data volumes. The result can be standard reports that take hours or even days—and an inability to deliver custom reports.

How do these companies compensate for slow, inflexible reporting systems? Many end up relying on spreadsheets and manual labor to consolidate information from disparate systems. Is this timely or an efficient use of company manpower? Usually not.

In today’s 24/7, digital world, real-time analytics

Getting the Best of Both Worlds with Queue Splitting (Bifurcated Driver)

The Linux networking stack has many features that are essential for IoT (Internet of Things) and data center networking, such as filtering, connection tracking, memory management, VLANs, overlay, and process isolation. These features come with a small overhead of latency and throughput for tiny packets at line rate.

DPDK (Data Plane Development Kit) allows access to the hardware directly from applications, bypassing the Linux networking stack. This reduces latency and allows more packets to be processed. However, many features that Linux provides are not available with DPDK.

What if there was a way to have ultra low latency and high throughput for some traffic, and full feature-set from Linux networking, all at the same time? This “utopia” is now possible with Queue Splitting (Bifurcated Driver).

Pushing the Limits of Kernel Networking

Note: The following post was authored by Alexander Duyck before leaving Red Hat earlier this month.  While Alex will be missed, his work continues in the capable hands of the Networking Services team.  To this end, I encourage you to “read on” and learn more about how we’ve turned up the heat on kernel networking with the beta release of Red Hat Enterprise Linux 7.2.


Over the last year I have been working at Red Hat as a part of the Linux Kernel Networking Services Team focused on improving the performance of the kernel networking data path.  Prior to working at Red Hat I had worked at Intel as a driver maintainer for their server drivers including ixgbe.  This has put me in a unique position to be able to provide tuning advice for both the network stack and the Intel device drivers.  Last month, at LinuxCon North America, I gave a presentation that summarizes most of the work that has been done to improve network performance in the last year, and the performance gains as seen by comparing Red Hat Enterprise Linux 7.1 versus an early (alpha) release of Red Hat Enterprise Linux 7.2.  The following is a recap of what I covered.

Select Your Destiny Friday

From news on the latest Red Hat product releases to essays on the hottest technologies – all authored by some of Red Hat’s best and brightest – the Red Hat Enterprise Linux Blog has been working to surface the information you need.  As we worked our way towards two years of posting goodness – we’ve covered everything from kpatch to containers.

That said, we have yet to ask you, our loyal readership, what you want to hear next.  So… for a change of pace, we’re asking you to “select your destiny”.  How does one go about “selecting their destiny”?  The answer is simple: by taking part in this straw poll.

We look forward to your selection!

What is Deep Container Inspection (DCI) and Why is it Important?

The format of container images is at the center of industry attention because it is so important to the adoption of containers.  With the advent of the Open Container Initiative (OCI), it seems appropriate to compare container images to network protocols.  Before TCP/IP became the defacto standard network protocol stack, each vendor was left to devise their own.  Some leveraged IPX/SPX, while others standardized on AppleTalk.  This made it difficult to create robust tooling.  Much like network protocols, standardizing the bit level format of a container image, allows the industry to focus on higher level business problems, and more importantly, their respective solutions.
