​Red Hat Platform-as-a-Service cloud loves containers

Red Hat is making it clear it's all containers all the time in its Red Hat OpenShift cloud.

When Red Hat launched its OpenShift Platform as a Service (PaaS) cloud in 2013, the focus was on making life easier for developers. OpenShift's theme remains the same but Red Hat has made it crystal clear that developing on the cloud today means using containers. The name says it all: Red Hat OpenShift Container Platform 3.3.

This latest release is built on Red Hat Enterprise Linux (RHEL) 7. It uses Docker for its containers and Kubernetes 1.3 for container management and DevOps.

Red Hat OpenShift Container Platform 3.3's new features include:

Jenkins Pipeline: This will provide for improved continuous development and improved A/B testing automation.

Deployments at cloud-scale: OpenShift now supports up to 1,000 nodes per computing cluster. This enables larger scale deployments to support for new applications and existing legacy applications in hybrid cloud environments. The inherent Kubernetes capabilities can now pro-actively monitor for and prevent against resource starvation and unplanned downtime.

Improved Security: Red Hat has integrated containers with Security Enhanced Linux (SELinux) for multi-tenant security and to OpenShift's integrated container registry. This enables administrators to manage their Docker-formatted container images and allows them to control access and image updates.

"Additional registry enhancements have been added to OpenShift. These include the ability to view container image details and manage access to images," the company said. "OpenShift also provides integrated user authorization and roles-based access controls for Kubernetes that integrate with enterprise Lightweight Directory Access Protocol (LDAP) systems. It also includes integrated security policies for container execution. This enables administrators to control user access, permissions, quotas and access to pull and run container images from one interface."

As before, you'll be able to use OpenShift on public, hybrid, and private clouds. The new OpenShift will be available for download on September 27. OpenShift Online and OpenShift Dedicated platforms are scheduled for update shortly thereafter.
