While there is a lot more than just the “Regulatory Technical Standard 25”, abbreviated to RTS 25 from now on, in the EU’s MiFID II regulations, the focus of this blog is all around RTS 25 and achieving compliance with the time synchronisation requirements this entails.
At a high level, the goal of MiFID ii is

Questions related to DNS and service discovery regularly come up during deployments of Identity Management (IdM) in Red Hat Enterprise Linux in a trust configuration with Active Directory. This blog article will shed some light of this aspect of the integration.
We will start with a description of the environment. Let us say that the Active Directory environment consist of

Most people don’t consider their average USB memory stick to be a security threat. In fact, in a social engineering experiment conducted in 2016 at the University of Illinois and detailed in this research paper, a group of researchers dropped 297 USB sticks outside in the parking lot, in the hallway, and classrooms. Of the 297 USB sticks dropped,

In Part 1, we created a working BIND container with local data storage. We can make changes on the local system that will get picked up in the running container. In this part, we’ll explore how we can manage the service from the host with

At the 2017 Red Hat Summit, several people asked me “We normally use full VMs to separate network services like DNS and DHCP, can we use containers instead?”. The answer is

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,

If you’re working with container images on Red Hat Enterprise Linux 7.1 or Red Hat Enterprise Linux Atomic Host, you might have noticed that the search and pull behavior of the included docker tool works slightly differently than it does if you’re working with that of the upstream project. This is intentional.
When we started the planning process for containers in RHEL 7.1, we had 3 goals in mind:
- Give control over the search path to the end-user administrator
- Enable a federated approach to search and discovery of docker-formatted container images
- Support the ability for Red Hat customers to consume container images and other content included as part of their Red Hat Subscription
The changes we implemented, which are documented on the Red Hat Customer Portal, affect three different areas of the tool:

What if you could run your existing Red Hat Enterprise Linux 6 applications on Red Hat Enterprise Linux 7 without porting or making changes to your source code? Today, we are pleased to announce the immediate availability of the Red Hat Enterprise Linux 6 platform image, which allows for the creation of Red Hat Enterprise Linux 6-based application containers. Applications that have been developed, tested, and certified for Red Hat Enterprise Linux 6 systems can now be deployed as a container and run on Red Hat Enterprise Linux 7 as a container host.
This new platform image allows customers to

Last week, as Red Hat Enterprise Linux 7 was making waves, the Red Hat Developer Blog posted Part 1 of an interview with Gene Kim, award-winning CTO and co-author of “The Phoenix Project”, and Red Hat IT’s DevOps Enablement team.
If you’re interested in learning more about Red Hat’s newly formed DevOps Enablement team – Part 2 is now available!
In followup to last week’s announcement, the Red Hat Enterprise Linux 7 Release Candidate (RC) is now publicly available for testing.
Vital for helping Red Hat’s strategic partners facilitate full certification of their applications and systems with Red Hat Enterprise Linux 7, Red Hat Enterprise Linux 7 RC is now accessible to all interested parties, from end users to enterprises, seeking to gain insight into how Red Hat redefines the enterprise operating system.
