What’s New in Red Hat Enterprise Linux Atomic Host 7.4?

We’re pleased to announce that Red Hat Enterprise Linux Atomic Host 7.4 is now generally available. Red Hat Enterprise Linux Atomic Host is a lightweight, container-optimized version of Red Hat Enterprise Linux. Red Hat Enterprise Linux Atomic Host couples the flexible, modular capabilities of Linux containers with the reliability and security of Red Hat Enterprise Linux in a reduced footprint, to decrease the attack surface and provide only the packages needed to light up hardware and run containers. Here’s a look at some of the major changes in 7.4.

Signed Images from the Red Hat Container Catalog

As a follow-up to my introduction of simple signing, I’m excited to announce that Red Hat is now serving signatures for Red Hat Container Catalog Images!

In May, Red Hat announced the Container Health Index, providing an aggregate safety rating for container images in our public registry. As part of our commitment to delivering trusted content, we are now serving signed images. This means that customers can now configure a Red Hat Enterprise Linux host to cryptographically verify that images have come from Red Hat when they are pulled onto the system. This is a significant step in advancing the security of container hosts, providing assurance of provenance and integrity and enabling non-repudiation. Non-repudiation simply means that the signer cannot deny their signature—a key security principle for digital transactions.

The Red Hat Ecosystem for Microservice and Container Development

Over the last couple years, microservices and containers have started to redefine the software development landscape. The traditional large Java or C# application has been replaced with multiple smaller components (microservices) which coordinate to provide the required functionality. These microservices typically run inside containers, which provide isolation and portability.

This approach has numerous benefits including being able to scale and replace microservices independently as well as reducing the complexity of individual components. However, it also brings more complexity to the system level; it takes extra effort and tooling to manage and orchestrate the microservices and their interactions.

This post will describe how Red Hat technology and services can be used to develop, deploy and run an effective microservice-based system.

10-FEB Webcast: Wicked Fast Container-Based Apps and Performance Tuning with Atomic Enterprise Platform

In a commissioned study conducted by Forrester Consulting on behalf of Red Hat, 44% of IT professionals identified performance in their top three concerns for adopting container technologies. Benchmarks indicate that containers result in equal or better performance than virtual machines in almost all cases, with the runtime costs of containers as “negligible”.

See You at ContainerCon in Seattle

If you’re looking at running Linux containers, you should be heading to ContainerCon in Seattle next week. Co-located with LinuxCon and CloudOpen, ContainerCon is where leading contributors in Linux containers, the Linux kernel, and related projects will get together to educate the community on containers and related innovations.

Red Hatters are contributing to over 40 seContainerConssions on this year’s agenda, including a keynote from Red Hat VP of Engineering Matt Hicks. In “Revolutionizing Application Delivery with Linux and Containers,” Matt will focus on how Linux containers are changing the way that companies develop, consume and manage applications and will emphasize how open source communities and projects like Docker and Kubernetes are delivering this next wave of enterprise application architecture.

If you’re attending ContainerCon, check out Matt’s keynote and some of the sessions below:
