Red Hat Enterprise Linux 7.4 Released
August 2, 2017
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
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.
Jim Totton, vice president and
general manager, Platforms Business Unit with Red Hat said, “The modern
enterprise will not be solely based in physical servers or cloud
services; rather, the path to digital transformation weaves across four
distinct technology footprints. The latest version of the world’s
leading enterprise Linux platform supports each of these deployment
methodologies with new security features, improved performance and
introduces new automation capabilities to cut through the inherent
complexities of heterogeneous datacenters.”
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
•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
•The introduction of LiveFS as a Technology Preview, which enables users
to install security updates and layer packages without a reboot.
Management and automation
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.
