Red Hat is evolving its server software portfolio with new OpenShift Platform-as-a-Service (PaaS) and Red Hat Enterprise Linux releases.
On the PaaS side, the OpenShift Enterprise 2.2 release is now available and includes integration with Red Hat's CloudForms cloud management platform. The new OpenShift Enterprise 2.2 release will also integrate with DNS and identity management systems, making it easier to deploy.
Red Hat additionally announced this week a beta of its Red Hat Enterprise Linux 7 Atomic Host operating system. The Atomic Host operating system was first announced in April as part of Red Hat's broader embrace of Docker containers.
Atomic is basically an optimized, small-footprint version of Red Hat Enterprise Linux 7, intended for the deployment of containerized applications.
While Atomic Host is based on Red Hat Enterprise Linux (RHEL), it also includes a few interesting features that are different than a typical RHEL release.
Red Hat is including a number of new capabilities inside of Atomic Host that will make container application deployment easier to manage and maintain. Updates are done with an RPM package based on rpm-ostree that enables users to roll back to a prior system state if needed.
Kubernetes Featured in Atomic Host Beta
The Google sponsored open-source Kubernetes container orchestration technology is also included in the Red Hat Enterprise Linux 7 Atomic Host beta.
"Kubernetes helps with horizontal scaling of multi-container deployments across a container host, and interconnecting multiple layers of the application stacks," Red Hat's blog post on the Atomic Host beta states. "This enables you to orchestrate services running in multiple containers into unified, large-scale business applications."
Security is also a part of the Atomic Host beta by way of the open-source SELinux (Security Enhanced) mandatory access control policy system. Additionally, Linux namespaces and c-groups provide further isolation and privacy for containers.
"These technologies prevent a compromised container from affecting other containers or the host and are the same proven technologies that have been delivering military-grade security to Red Hat customers for more than 10 years," Red Hat stated.
The ability to build and run container images is another key attribute of the Red Hat Enterprise Linux 7 Atomic Host beta. Deployment of containers can be made to physical hardware as well as virtual infrastructure, including VMware's vSphere, Amazon Web Services and Red Hat's own virtualization and OpenStack cloud platforms.
