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

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

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.

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!
In March, we announced the general availability of Red Hat Enterprise Linux 7.1, the first update to our Red Hat Enterprise Linux 7 platform. In addition, we also announced the general availability of Red Hat Enterprise Linux Atomic Host, our first container-optimized host platform. Today, we are pleased to announce the beta availability of Red Hat Enterprise Linux 7.2.
Red Hat Enterprise Linux 7.2 beta includes a number of new features and enhancements – while continuing to provide the stability, reliability, and security required to meet the demands of both modern datacenters and next-generation IT environments.
Interested in learning more? For more information on the beta release of Red Hat Enterprise Linux 7.2 you can review the release notes in the Red Hat Customer Portal.
Ready to get started? If you’re an existing Red Hat customer (with an active Red Hat Enterprise Linux subscription), you can access and download Red Hat Enterprise Linux 7.2 beta via the Software & Download Center.
Given the recent massive spike in interest in Linux Containers, you could be forgiven for wondering, “Why now?”. It has been argued that the increasingly prevalent cloud computing model more closely resembles hosting providers than traditional enterprise IT, and that containers are a perfect match for this model.
Despite the sudden ubiquity of container technology, like so much in the world of open source software, containerization depends on a long series of previous innovations, especially in the operating system. “One cannot resist an idea whose time has come.” Containers are such an idea, one that has been a long time coming.

If you’re looking at running Linux containers, you should be heading to ContainerCon in Seattle next week. Co-located with LinuxCon and CloudOpen, ContainerCon is where leading contributors in Linux containers, the Linux kernel, and related projects will get together to educate the community on containers and related innovations.
Red Hatters are contributing to over 40 sessions on this year’s agenda, including a keynote from Red Hat VP of Engineering Matt Hicks. In “Revolutionizing Application Delivery with Linux and Containers,” Matt will focus on how Linux containers are changing the way that companies develop, consume and manage applications and will emphasize how open source communities and projects like Docker and Kubernetes are delivering this next wave of enterprise application architecture.
If you’re attending ContainerCon, check out Matt’s keynote and some of the sessions below:

Perhaps you’ve been charged with developing a container-based application infrastructure? If so, you most likely understand the value that containers can provide to your developers, architects, and operations team. In fact, you’ve likely been reading up on containers and are excited about exploring the technology in more detail. However, before diving head-first into a discussion about the architecture and deployment of containers in a production environment, there are three important things that developers, architects, and systems administrators, need to know

On Thursday, July 30, 2015, Red Hat will be presenting a free webinar for system administrators, engineers, and architects to learn what’s new with Red Hat Enterprise Linux.
During this webinar Red Hat curriculum manager and Red Hat Certified Architect, Michael Jarrett, will teach you about the new and changed features in Red Hat Enterprise Linux 7. He’ll focus on system administration topics that have changed significantly or are particularly important in Red Hat Enterprise Linux 7. He’ll also discuss the skills and expert knowledge needed to measure and influence performance on these systems.
Then Pete Hnath, director of curriculum, will show you how easy it is to train on Red Hat Enterprise Linux 7 and update your skills with the new Red Hat Learning Subscription, a year-long, all-access pass to more than 30 online learning courses.
With the release of Red Hat Enterprise Linux 6.7, we’re happy to also announce general availability of Red Hat Access Insights, a new hosted service from Red Hat designed to help customers proactively identify and resolve issues that could impact business operations.
Given the complexity and scale of modern IT environments, we recognize that it can be increasingly complicated to monitor, maintain, and secure enterprise infrastructure. By tapping into Red Hat’s collective experience
