Red Hat Enterprise Linux 7.2 Boosts Network
Performance and Delivers Additional Enhancements to Support the
Development and Deployment of Container-Based Applications
Red Hat, Inc. (NYSE:RHT), the world's leading provider of open
source solutions, today announced the general availability of Red
Hat Enterprise Linux 7.2, the latest release of Red Hat Enterprise
Linux 7. Red Hat Enterprise Linux 7.2 continues Red Hat's goal of
redefining the enterprise operating system by providing a trusted
path towards the future of information technology without
compromising the needs of the modern enterprise.
New features and capabilities focus on security,
networking, and system administration, along with a
continued emphasis on enterprise-ready tooling for the development
and deployment of Linux container-based applications. In addition,
Red Hat Enterprise Linux 7.2 includes compatibility with the new
Red Hat Insights, an add-on operational analytics offering
designed to increase IT efficiency and reduce downtime through the
proactive identification of known risks and technical issues.
Security
Retaining Red Hat's commitment to security, including meeting
the needs of financial, government, and military customers, Red Hat
Enterprise Linux 7.2 continues to provide new security capabilities
and features.
True security requires both a secure foundation and secure
configuration of systems. OpenSCAP is an implementation of the
Security Content Automation Protocol that analyzes a system for
security compliance. The new Open SCAP Anaconda plug-in allows use
of SCAP based security and configuration analysis during the
installation process, ensuring a secure starting point for system
deployment.
A critical part of secure distributed systems is being able to
trust the address resolution performed by DNS servers. DNSSEC
extends DNS to provide a secure chain of trust for address
resolution. The Red Hat Identity Management system (IdM) now
supports DNSSEC for DNS zones.
Networking
Networking performance in Red Hat Enterprise Linux 7.2 has been
significantly improved - with throughput doubled in many network
function virtualization (NFV) and software defined networking (SDN)
use cases. Other enhancements to the kernel networking subsystem,
include:
- Tuning the network kernel stack to
dramatically improve packet processing time, enable Red Hat
Enterprise Linux 7.2 to perform at physical line rates in advanced
(virtual and containerized) workloads.
- Inclusion of the Data Plane Development
Kit (DPDK), which makes it possible to rapidly develop low-latency
and high throughput custom applications capable of direct packet
processing in user space for NFV and other use cases. Prior to this
enhancement, systems were limited to running only one type of
application (DPDK-enabled or traditional-network enabled.)
Enhancements in Red Hat Enterprise Linux 7.2, specifically the
introduction of a new bifurcated driver, now allow for both types
of applications to be hosted on the same system thus consolidating
physical hardware.
- The addition of TCP (DCTCP), a feature
for solving TCP congestion problems in data centers that works
smoothly across Windows- and Red Hat Enterprise Linux-based hosts
to maximize throughput and efficiency.
Linux Containers
Red Hat Enterprise Linux 7.2 features many improvements to the
underlying container support infrastructure. Updates are included
for the docker engine, Kubernetes, Cockpit and the Atomic command.
In addition, Red Hat Enterprise Linux Atomic Host 7.2, the latest
version of Red Hat's container workload-optimized host platform, is
available with most Red Hat Enterprise Linux 7.2 subscriptions.
Also available today is the beta of the Red Hat Container
Development Kit 2, a collection of images, tools, and documentation
to help application developers simplify the creation of
container-based applications that are certified for deployment on
Red Hat container hosts, including Red Hat Enterprise Linux 7.2,
Red Hat Enterprise Linux Atomic Host 7.2 and OpenShift Enterprise
3.
System Administration
As managing the modern datacenter at scale becomes increasingly
complex, Red Hat Enterprise Linux 7.2 includes new and improved
tools to deliver a more streamlined system administration
experience. Highlighting these updates is the inclusion of
Relax-and-Recover, a system archiving tool that enables
administrators to create local backups in ISO format that can be
centrally archived and replicated remotely for simplified disaster
recovery operations.
Red Hat Insights
Red Hat Enterprise Linux 7.2 is compatible with Red Hat
Insights, an operational analytics service designed for the
proactive management of Red Hat Enterprise Linux environments.
Available for up to 10 Red Hat Enterprise Linux 7 systems at no
additional cost, the offering is designed to help customers detect
technical issues before they impact business operations by
analyzing infrastructure assets and identifying key risks and
vulnerabilities through continuous monitoring and analysis. Red Hat
Insights provides resolution steps to help IT managers and
administrators respond to these issues and potentially prevent
future problems.
Red Hat Enterprise Linux Server for ARM 7.2 Development
Preview
Red Hat is also making available Red Hat Enterprise Linux Server
for ARM 7.2 Development Preview, which was first made available to
partners and their customers in June 2015. This Development Preview
enables new partner hardware and additional features for the ARM
architecture.
