Features

Optimized for Containers

Deploy a secure, integrated host platform that is designed to run container images with optimizations for scalability, density, and performance.

Atomic Updating and Rollback

A new, simplified update mechanism for host OS lets you download and deploy updated versions in a single step. With built-in retention of a previous version of the host OS, you can easily rollback to an earlier state.

Security

Secure and isolate applications with SELinux in containers, reducing potential attack surfaces and ensuring that if a container process goes down or is compromised, other applications and the host remain safe and functional.

Flexibility to Deploy Across the Open Hybrid Cloud

Deploy Red Hat Enterprise Linux 7 Atomic Host to physical, virtual and public and private cloud environments, including Amazon Web Services and Google Compute Engine.

Red Hat Enterprise Linux for Real Time

Red Hat Enterprise Linux for Real Time is a real-time computing platform for deadline-oriented applications and time-sensitive workloads. Based on a specialized version of the stock Red Hat Enterprise Linux 7 kernel, Red Hat Enterprise Linux for Real Time builds on the reliability, scalability, and performance of the world’s leading enterprise Linux platform, ensuring the highest levels of predictability for consistent, low-latency response times.

Features

Highly Deterministic Performance

Red Hat Enterprise Linux for Real Time minimizes the potential for any deviations in application performance through an optimized scheduler that increases preemption opportunities.

Integrated Tuning Tools

Red Hat Enterprise Linux for Real Time uses the same system tuning tools available in Red Hat Enterprise Linux 7. It also includes additional tools to tune real-time characteristics. As each real-time computing application is different, Red Hat Enterprise Linux for Real Time allows for easy, on-premises adjustments of priorities, interrupts, and more.

Full Application Compatibility

The Red Hat Enterprise Linux for Real Time user space is derived from that of Red Hat Enterprise Linux 7, so applications certified to run on Red Hat Enterprise Linux 7 can run unmodified on Red Hat Enterprise Linux for Real Time.

High Resolution Timers

Nanosecond timer resolution allows systems to process data with greater accuracy.
