Google Kubernetes Engine vs OpenShift: What are the differences?
Developers describe Google Kubernetes Engine as "Deploy, manage, and scale containerized applications on Kubernetes, powered by Google Cloud". Container Engine takes care of provisioning and maintaining the underlying virtual machine cluster, scaling your application, and operational logistics like logging, monitoring, and health management. On the other hand, OpenShift is detailed as "Red Hat's free Platform as a Service (PaaS) for hosting Java, PHP, Ruby, Python, Node.js, and Perl apps". OpenShift is Red Hat's Cloud Computing Platform as a Service (PaaS) offering. OpenShift is an application platform in the cloud where application developers and teams can build, test, deploy, and run their applications.
Google Kubernetes Engine can be classified as a tool in the "Containers as a Service" category, while OpenShift is grouped under "Platform as a Service".
Some of the features offered by Google Kubernetes Engine are:
- Docker support - Improve the predictability of your deployments with Docker containers. Containers make it easy to deploy applications across environments.
- Better ops - Give ops a better system, starting with a managed compute cluster. Container Engine takes care of provisioning and maintaining the underlying virtual machines and operational logistics like logging, monitoring, and health management.
- Declarative management - Use declarative syntax to define your application requirements. Container Engine will actively manage your application, ensuring your containers are running and scheduling additional as needed.
On the other hand, OpenShift provides the following key features:
- Built-in support for Node.js, Ruby, Python, PHP, Perl, and Java (the standard in today's Enterprise)
- OpenShift is extensible with a customizable cartridge functionality that allows developers to add any other language they wish. We've seen everything from Clojure to Cobol running on OpenShift.
- OpenShift supports frameworks ranging from Spring, to Rails, to Play
"Powered by kubernetes" is the top reason why over 15 developers like Google Kubernetes Engine, while over 95 developers mention "Good free plan" as the leading cause for choosing OpenShift.
OpenShift is an open source tool with 913 GitHub stars and 561 GitHub forks. Here's a link to OpenShift's open source repository on GitHub.
According to the StackShare community, Google Kubernetes Engine has a broader approval, being mentioned in 248 company stacks & 252 developers stacks; compared to OpenShift, which is listed in 76 company stacks and 358 developer stacks.

I needed a PaaS provider that didn't drop all the time and it's hard to find a good option for PHP applications. Openshift takes care of it. They are a little behind on PHP versions, but that can be solved with a custom cartridge. It requires a little more elbow grease to get rolling when you want to implement something they don't already have, but their quickstarts are great to get rolling with the basics quickly.
Since it is mostly backed by Kubernetes, GCE looks really promising. I did run into some fuzzy bugs as I did expect with Alpha.
I recommend giving it a lab-test-try and engage in discussion about Kubernetes.
SG-TravelBuddy server application is hosted on Red Hat OpenShift Online (v3). SG-TravelBuddy mobile (Android) app is connecting to this server for data operations.
used this when setting up the kubernetes infrastructure for a client.
Our developer experience system is on Google Kubernetes Engine.
