Last week, Intel launched the new family of Intel® Xeon® scalable processors with new features such as Intel Advanced Vector Extensions 512 (Intel AVX-512), which boost performance of computationally intensive tasks, a new Intel Mesh Architecture for reduced system latency, Intel QuickAssist Technology for hardware acceleration of cryptography and data compression operations and integrated high-speed fabric with Intel Omni-Path Architecture. According to Intel,

As predicted in one of my earlier posts, more and more customers are starting to seriously evaluate and move off of third party Active Directory integration solutions. They want to use or at least consider leveraging identity management technologies available in Red Hat Enterprise Linux.
In the calls and face to face meetings as well as during customer presentations at Red Hat Customer Convergence events, Red Hat Summit, Defence in Depth and other conferences I get a lot of questions about such migration. As it is becoming a common theme, I decided to consolidate some of the thoughts, ideas, and best practices on the matter in a single blog post.

In Part 1 of this series, we looked at core improvements for Identity Management (IdM) in Red Hat Enterprise Linux (RHEL) 7.3, as well as manageability and other improvements. In the second half, we’re going to look at interoperabilty, and Active Directory integration.

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.

When building anything substantial, such as a house or bridge, you start by laying down a solid foundation. Nothing changes this aspect of building brick by brick when you move from traditional constructions to application development and architecting your supporting infrastructure. Throw in Cloud terminology and you might think that the principles of a solid foundation are a bit flighty, but nothing is further from the truth.
When looking to manage an organization’s journey into their digital future, CIOs are dealing with a lot of challenges. Challenges that they face on the road to digital transformation can be daunting as first glance, but must be embraced to properly navigate the road to success.

On August 24th of this year Red Hat announced the newest release of Red Hat Virtualization (RHV) 4.0.
Just two months later the Red Hat Cloud Suite tooling (known as the Cloud Deployment Planner) was updated to provide you with

What if I told you that you can have your Red Hat Enterprise Linux (RHEL) based Cloud infrastructure, with Red Hat Virtualization, OpenStack, OpenShift and CloudForms all setup before you have to stop for lunch?
Would you be surprised?
Could you do that today?
In most cases I am betting your answer would be not possible, not even on your best day. Not to worry, the solution is here and it’s called the QuickStart Cloud Installer (QCI).

There are two supported protocols in Red Hat Enterprise Linux for synchronization of computer clocks over a network. The older and more well-known protocol is the Network Time Protocol (NTP). In its fourth version, NTP is defined by IETF in RFC 5905. The newer protocol is the Precision Time Protocol (PTP), which is defined in the IEEE 1588-2008 standard.
The reference implementation of NTP is provided in the ntp package. Starting with Red Hat Enterprise Linux 7.0 (and now in Red Hat Enterprise Linux 6.8) a more versatile NTP implementation is also provided via the chrony package, which can usually synchronize the clock with better accuracy and has other advantages over the reference implementation. PTP is implemented in the linuxptp package.

Cloud conversations are evolving at a seemingly ever increasing pace. In my experience, nearly all “…what is the cloud?” type conversations have long since past. In fact, for some organizations, private and public clouds are now central to daily business operations. For the both the early and late majority, however, their (usually large) install base of traditional applications makes the cloud far from reality. These organizations tend to have significant investments in proprietary virtualization, management, and operations technologies, and it’s not a given that these applications are cloud ready (today). While many proprietary technology vendors offer re-packaged versions of existing products to create a thin veil of “cloudiness” – this style of cloud enablement usually comes at a heavy price
