Red Hat has announced the general availability of Red Hat Enterprise Linux 7.4 with new automation capabilities designed to limit IT complexity while enhancing security.
Red Hat Enterprise Linux 7.4 offers new automation capabilities designed to limit IT complexity while enhancing workload security and performance for traditional and cloud-native applications. This provides a powerful, flexible operating system backbone to address enterprise IT needs across physical servers, virtual machines and hybrid, public and multi-cloud footprints.
From traditional physical servers and virtual machines to next-generation cloud and container services, the operating system serves as a critical linchpin in connecting deployment footprints across the enterprise. Red Hat Enterprise Linux 7 acts as this keystone by pairing open source innovation with enterprise-grade stability, providing a foundation for digital transformation while still maintaining existing systems and workloads.
As threats to IT infrastructure evolve, enterprises require more security innovation in their software stack to help prevent breaches and more proactively manage vulnerabilities. This innovation starts at the operating system level, and Red Hat Enterprise Linux 7.4 brings to bear new and enhanced features designed to foster a more secure production environment for mission-critical workloads, both cloud-native and traditional. This includes:
- Updated audit capabilities to help simplify how administrators filter the events logged by the audit system, gather more information from critical events and to interpret large numbers of records.
- USB Guard, a feature that allows for greater control over how plug-and-play devices can be used by specific users to help limit both data leaks and data injection.
- Enhanced container security functionality with full support for using SELinux with OverlayFS helps secure the underlying file system and provides the ability to use docker and use namespaces together for fine-grained access control.
Modern business applications require more bandwidth and increased storage, placing a performance strain on traditional operating systems and hardware. Engineered to meet the needs of organizations seeking to both modernize and optimize their enterprise IT infrastructure, Red Hat Enterprise Linux 7 offers new features designed to improve the performance of both networking and storage. New features include:
- Support for NVMe Over Fabric helps to provide customers with increased flexibility and reduced overhead when accessing high performance NVMe storage devices located in the data center on both Ethernet or Infiniband fabric infrastructures.
- General enhancements to Red Hat Enterprise Linux’s performance when deployed on the public cloud, highlighted by decreased boot times to better enable mission-critical applications to start sooner, and support for the Elastic Network Adapter (ENA) on Amazon Web Services (AWS) to enable new network capabilities.
Linux Containers and Red Hat Enterprise Linux Atomic Host
Linux containers present an evolution in how businesses develop, deploy, and manage modern applications, helping enterprises scale to new levels of operational efficiency, speed application development and drive increased flexibility in managing application life cycles. Based on Red Hat Enterprise Linux 7.4, the latest version of Red Hat Enterprise Linux Atomic Host further refines enterprise-grade Linux containers with enhancements that include:
- Improved security without sacrificing performance, thanks to integrated support for SELinux and OverlayFS, as well as full support for the overlay2 storage graph driver.
- Full support for package layering with rpm-ostree, providing a means of adding packages like monitoring agents and drivers to the host operating system.
- The introduction of LiveFS as a Technology Preview, which enables users to install security updates and layer packages without a reboot.
Management and automation
With datacenter footprints that span from bare-metal to the cloud, the complexity associated with controlling IT environments continues to increase. Complementing the capabilities of Red Hat Satellite and automation via Ansible Tower, Red Hat Enterprise Linux 7.4 introduces Red Hat Enterprise Linux System Roles as a Technology Preview. System Roles provide a common management interface across all major versions of Red Hat Enterprise Linux, enabling an automated workflow via Ansible automation to be created once and used across large, heterogeneous Red Hat Enterprise Linux deployments without additional modifications.
Red Hat Enterprise Linux for multiple architectures
Red Hat remains committed to providing customer choice when it comes to datacenter infrastructure. Red Hat Enterprise Linux 7.4 maintains this commitment with availability across multiple architectures, including IBM Power, IBM z Systems and 64-bit ARM (as a Development Preview). For the IBM Power Little Endian architecture, this release enables support for the High Availability and Resilient Storage Add-Ons as well as the Open Container Initiative (OCI) runtime and image format.
Welcome to world of 2099
The world of 2099 will be unrecognisable from the world of today, but it can be predicted, says one visionary. ARTHUR GOLDSTUCK met him in Singapore.
Futuristic structures tower over the landscape. Giant, alien-looking trees light up with dazzling colours amid the hundreds of plant species that grow up their trunks. Cosmetic stores sell their wares via public touch-screens, with products delivered instantly in drawers below the screens.
This is not a vision of the future. It is a sample of Singapore today. But it is also an inkling of the world we may all experience in the future.
Singapore was the venue, last week, of the World Cities Summit, where engineers, politicians, investors and visionaries rubbed shoulders as they talked about the strategies and policies that would enhance urban living in the future.
As part of the Summit, global payment technologies leader Mastercard hosted a small media briefing by one of Singapore’s leading thinkers about the future, Dr Damian Tan, managing director of Vickers Venture Partners. The company’s slogan “We invest in the extraordinary,” offers a small clue to Tan’s perspective.
“We look as far forward as 2099 because, as a venture capital firm, we invest in the long term,” he tells a group of journalists from Africa and the Middle East. “Companies explode in growth because there is value in the future. If there is no growth, they won’t explode.”
The big question that the Smart Cities Summit and Mastercard are trying to help answer is, what will cities look like in the year 2099? Tan can’t give an exact answer, but he offers a framework that helps one approach the question.
“If you want to look at 81 years into the future, and understand the change that will come, you need to double that amount and look into the past. That takes us to 1856. The difference between then and now is the difference you can expect between now and 2099.”

Win a Poster Heater with Gadget and Takealot.com
This winter Gadget and Takealot.com are giving away three Poster Heaters, which look like posters but become heaters when you plug them in.
Three Gadget readers will each win a unit, valued at R550 each. To enter, follow @GadgetZA and @Takealot on Twitter and tell us on the @GadgetZA account how many Watts the heater consumes.
What’s the big deal about these heaters? Many of us are struggling to keep the balance between soaring electricity costs and the need to keep warm this winter.
However, the recently launched Poster Heater by EasyHeat and distributed in South Africa by Takealot.com is not only one of the most cost effective electric heaters currently on the market, it is also easy to setup and use.
As the name indicates, it is a poster similar to one you would hang on a wall. But, plug it in and it turns into a 300 Watt heater. The Poster Heater isn’t designed to heat hallways or large rooms, but rather smaller ones like a bedroom or a baby’s nursery or a dressing room.
It uses radiant heating, which means that it heats up in a couple of minutes and the heat is directed at the objects or people around it, quickly taking the chill out of the air and providing a comfortable ambient temperature.
The other advantage of radiant heating is that it doesn’t dry out the air like infrared or gas heaters. Users also don’t have to worry about their children or pets getting too close to it because, even though it gets hot, it can be touched.
To enter the competition follow the steps below:
Competition entry details:
3. The competition closes on 31 July 2018.
4. Winners will be notified via Twitter on 1 August and Takealot.com will be in touch to organise delivery.
5. The competition is only open to South African residents.
