CoreOS rkt / Container Linux (project ended) vs Red Hat OpenShift on IBM Cloud

Likelihood to Recommend

CoreOS rkt is well suited for any development environment where operating systems and hardware are not homogeneous. CoreOS rkt allows us to write code on one machine with the confidence that it will work on any other. This has been immensely helpful as our developers are often switching to the latest and greatest machines and operating systems. CoreOS rkt is less suited for environments that are not Software as a Service. There is often no need to bring the entire developer environment and associated dependencies when delivering a one time product. In these environments CoreOS rkt just adds unneeded overhead.

OpenShift is well suited if you want to use docker and kubernetes but you want to hide the complexity of these two technologies. It gives a developer much more freedom in terms of code deployment, build process and implementation. One of its strengths is scaling and you can easily configure for each application.

We tested Red Hat OpenShift on premise but we decided to go for a public cloud to reduce our infrastructure and pay for what we use.
