logo OpenShift Kickstarter Program

Red Hat announced the introduction of their latest OpenShift technology to the public in October: the OpenShift Container Platform 3.11 update and release of the Red Hat OpenShift Container Engine. The release of the OpenShift Container Engine has piqued the interest of many in the Red Hat community keen to know what the difference is between OpenShift Container Platform and OpenShift Container Engine. In this article, the Tier 2 Consulting team lay out the basics of the latest OpenShift technology.

OpenShift Container Platform 3.11

OpenShift Container Platform 3.11 is the latest update of Red Hat’s popular platform. The 3.11 update will be the final 3.xx version of OpenShift Container Platform before the release of version 4.0.

Current users are probably aware of the benefits of using this hybrid cloud application platform to deploy new and existing applications on secure, scalable resources with minimal configuration and management overhead. The new update continues to improve on the existing platform built on Red Hat Enterprise Linux and Kubernetes. And users will be pleased to know that the 3.11 update will be supported on Red Hat Enterprise Linux 7.4 and 7.5, as well as Atomic Host 7.5 and more.

While it remains an update within the 3.xx series, there have been a number of notable changes from the previous versions of OpenShift Container Platform. These include making sure that Curator now works with Elasticsearch 5, new SCC options, Hawkular being deprecated, the introduction of a new registry source for Red Hat images as well as Red Hat’s new recommendation to use the overlayF5 storage driver instead of Device Mapper. There are also numerous bug fixes targeting many aspects of the platform, including installation, builds, logging, monitoring and storage.

For more information on the specific changes and bug fixes that have been made in version 3.11, you can read the below document on the OpenShift website.

Red Hat OpenShift Container Engine

Alongside the update to the OpenShift Container Platform, Red Hat has also announced the release of the new OpenShift Container Engine. Built on the same enterprise Kubernetes core platform, with the same crucial Linux, container runtime, networking, management and security capabilities; so what is the difference between OpenShift Container Platform and OpenShift Container Engine?

OpenShift Container Platform or OpenShift Container Engine – what’s the difference?

As a minimal configuration of the Platform, the Container Engine does not offer the advanced management, networking or developer experience found in the OpenShift Container Platform. Essentially, this new Container Engine serves as a technology to assist customers who wish to bring their current network, management and DevOps services to OpenShift.

Customers using OpenShift Container Engine are of course able to stick with the Container Engine or upgrade to the more sophisticated OpenShift Container Platform if they decide that they are in need of the more in-depth technical capabilities on offer.

Whether you will be using the new Container Engine or not, it’s important to remember that both platforms deliver the Red Hat enterprise Kubernetes experience. Beyond that, both provide a consistent, reliable and CNCF-certified platform to power containerised workloads across hybrid cloud environments and are extensible to leading container solutions with Red Hat partners. And you can rest assured that all OpenShift technology comes with the strong backing and support that Red Hat is renowned for.

Red Hat hopes to continue providing users with even more choice and flexibility when it comes to managing their hybrid cloud environments. For more information, you can read Red Hat’s release notes on the OpenShift Container Engine here.
